Hawaii Weather in December: What to Expect on Your Trip

What is Hawaii weather in December actually like?

Hawaii weather in December is warm enough for beach days in Honolulu, where the average high is 77.7°F (25.4°C) and the average low is 70.9°F. Honolulu averages 8 rainy days, 9.9 hours of sunshine a day, and 75% humidity in December, so pack for sunshine without assuming every day will be dry.

That's a pretty appealing trade if you're leaving a cold part of the mainland. You can eat breakfast outside, spend an afternoon on the sand, and walk to dinner without winter clothing. But don't picture an endless run of cloudless resort days. December falls in Hawaii's wetter season, and short drives can take you into noticeably different weather.

Before comparing islands, here's the useful baseline. Every figure in this table is a Honolulu average from the 2006 to 2025 period. These are not forecasts or statewide averages.

The differences are small enough that the feel of your trip will depend on where you stay, what you do, and the weather during your actual travel dates. The averages tell you what to pack and what to expect, not which afternoon will be sunny.

Does December feel warm enough for the beach?

For most visitors, yes. A Honolulu average high of 77.7°F is comfortable for sitting on the beach, having lunch outdoors, and spending time by a pool. It's warm, but not necessarily the kind of blazing heat you might imagine when someone says tropical vacation. If you love intense heat, you could find the breeze and cloud cover less beach-perfect than you'd hoped.

Think about your preferred beach day. If you're happy reading in the shade, walking along the water, and taking a swim when conditions are good, December sounds inviting. If your vacation only feels successful when you can sunbathe under clear skies from morning until evening, the rainy season is a real drawback.

Does Honolulu get chilly at night in December?

The average low is 70.9°F, so evenings generally call for light layers rather than a heavy coat. A casual shirt or dress can work for dinner, but an open-air restaurant, a breezy shoreline, or a damp evening might make a thin sweater feel useful. Bring something you can throw on without thinking about it.

You also don't need separate winter and summer wardrobes. A small bag of breathable clothes, swimwear, and a light layer is more practical than stuffing your suitcase with outfits for every possible temperature.

Does it rain a lot in Hawaii in December?

Rain is the biggest reason to be realistic about a December trip. Honolulu averages 8 rainy days, and December is its wettest month in this dataset, with 62 mm (2.4 in) of rain. That sounds dramatic until you remember that a rainy day doesn't automatically mean a full day trapped inside your hotel.

The islands have a complicated mix of wind, mountains, and coastlines. The National Weather Service's Hawaii climate overview explains why places exposed to the trade winds tend to be wetter, while sheltered areas are often sunnier and drier. Winter weather systems can also bring widespread cloud and rain. The important point is that the weather on your hotel balcony isn't always the weather on the other side of the island.

Does a rainy day mean it will rain all day?

Not necessarily. You might get a passing shower and then head back outside, or you might get a weather system that keeps conditions unsettled for longer. The Honolulu average doesn't say how long rain lasts, how hard it falls, or exactly when it arrives. Don't turn that rainy-day count into a promise that most of the day will be dry.

A better plan is to keep a few activities interchangeable. If skies look promising, choose the beach or an outdoor walk. If the forecast turns wet, switch to a museum, a leisurely meal, indoor shopping, or a covered attraction. Then check conditions again before giving up on the rest of the day.

Which side of a Hawaiian island gets less rain?

As a general rule, windward areas on the east and north sides receive more rain, while leeward areas on the west and south sides are drier and sunnier. Mountains and the direction of the wind make a big difference. That rule is useful for choosing a base, but it isn't a guarantee for any particular beach, neighborhood, or day.

If reliable outdoor time matters to you, look at the exact location of the hotel, not just the island's name. Read recent guest comments about shade, wind exposure, and access to beaches. A place that looks close to everything on a map can still put you on a wetter side of the island than you expected.

There's a tradeoff here. Greener windward scenery often comes with clouds and showers, while a sunnier leeward base may mean extra driving to reach lush valleys, trails, and certain sightseeing stops. Decide which experience matters more rather than assuming you'll get everything from the same hotel.

Is November or January better than December for Honolulu weather?

It depends on the reason for your trip. All these figures refer only to Honolulu, so they're useful for choosing travel dates on Oahu, not ranking the weather across Hawaii. If you're flexible, look at the little differences instead of expecting a completely different season.

Is November warmer than December in Honolulu?

Yes, by the averages supplied here. November has a high of 79.9°F (26.6°C) and a low of 73°F, compared with December's high of 77.7°F (25.4°C) and low of 70.9°F. November also averages 7 rainy days and 10.2 hours of sunshine a day, while December averages 8 rainy days and 9.9 hours.

In practical terms, November gets my vote if your dates are flexible and your priority is a slightly warmer Honolulu beach trip. That doesn't mean a November vacation is guaranteed to be sunny or a December vacation is likely to be ruined. Weather doesn't follow a monthly table as neatly as a booking calendar.

Is January colder or less rainy than December?

January is a touch cooler in Honolulu, with an average high of 76.8°F (24.9°C) and a low of 69.4°F. It averages 7 rainy days and 10.2 hours of sunshine a day. December is slightly warmer in this comparison but also has the higher rainy-day count and less daily sunshine.

Would I move a trip into January just because of those numbers? Probably not if December is the time you can travel with family or friends. Your hotel location, forecast, budget, and activity preferences can matter more. If the choice is completely open, though, it's fair to compare the months before committing.

Which Hawaiian island should you visit in December?

Start with what you want to do instead of chasing an imaginary island with perfect winter weather. The Honolulu figures above are the only local measurements used in this guide. They tell you about Honolulu on Oahu, not the exact conditions on Maui, Kauai, Hawaii Island, or even every part of Oahu.

Is Oahu a good choice for a first Hawaii trip in December?

Oahu is an easy choice if you want beach time mixed with restaurants, city attractions, shopping, cultural sites, and backup options for showers. Staying in or near Honolulu gives you ways to change your plans without spending your entire vacation driving. That flexibility is especially helpful in a month when the weather can change.

There's a downside. If you're dreaming of a quiet stretch of sand with hardly anyone around, a popular Honolulu beach neighborhood may feel too developed. Choose your lodging carefully, consider quieter areas if they fit your plans, and don't assume a famous beach will feel private just because it's December.

What about Maui, Kauai, and Hawaii Island in December?

Each can make a wonderful trip, but you shouldn't use the Honolulu temperature, sunshine, or rainfall figures as their forecasts. Conditions vary by coast, terrain, and elevation. If you're comparing resorts, look up the forecast for the exact area where you'll stay and pay attention to which side of the island faces the prevailing wind.

For a scenery-focused trip, a lush landscape and passing showers may be part of what you enjoy. For a beach-centered trip, a leeward location may be the better starting point. For a road trip, plan for conditions to change as you move between coasts and higher ground. None of those choices comes with a promise of perfect skies.

My advice is simple: choose the island for its activities, then choose the neighborhood with the weather tradeoffs you can live with. Picking a destination only because someone online called it the driest is a good way to be disappointed.

Can you swim in Hawaii in December?

Swimming can absolutely be part of a December vacation, but comfortable air temperatures are not the same as safe ocean conditions. Surf, currents, visibility, and local beach conditions change. Winter can bring powerful surf to exposed shorelines, especially north-facing ones. A pretty photo of a beach tells you nothing about whether entering the water is a good idea that day.

Before swimming, check beach warning signs, lifeguard advice, and the current forecast. If the water looks rough, don't try to convince yourself that you'll be fine because other people are in it. Move to a more sheltered, lifeguarded beach when conditions allow, or enjoy the shore without going in.

Is snorkeling a good idea in December?

It can be, when conditions are calm and visibility is good. Book with a reputable operator who chooses locations based on the day's conditions and explains what happens if the sea is unsafe. If snorkeling is your main reason for visiting, keep more than one possible outing in your itinerary so a rough-water day doesn't wreck the entire plan.

Don't buy a nonrefundable ocean excursion just because the weather averages sound warm. Ask about cancellation terms, weather decisions, and whether beginners are welcome. Being flexible with the schedule is more useful than trying to predict ocean safety from a monthly temperature average.

Are Hawaii beaches good for families in December?

They can be, but families should pick beaches for safe conditions and lifeguard coverage, not for the prettiest pictures. With kids, a calm place to splash or build sandcastles is often more enjoyable than a dramatic shore break. Bring sun protection even when the sky looks gray, and keep dry clothes handy for a sudden shower.

If your children want constant pool time, look for a hotel with a pool that suits their ages and a comfortable place to retreat during rain. A convenient hotel setup can matter more than a small difference in average monthly weather.

What should you pack for Hawaii in December?

Pack for warm coastal days, occasional wet weather, air-conditioned spaces, and the activities you've actually booked. You don't need to dress as if you're traveling to a mainland winter destination, but you also shouldn't bring nothing except swimsuits and sandals. December rewards a simple, practical wardrobe.

• Light everyday clothes: Breathable shirts, shorts, casual dresses, and comfortable pieces that dry quickly.
• Swimwear and a cover-up: Useful for beach stops, pool time, and heading to lunch without changing your entire outfit.
• A thin sweater or light jacket: Handy for breezy evenings, cool indoor spaces, or sitting outside after sunset.
• A compact rain layer: Something easy to carry when a shower catches you away from your hotel.
• Comfortable walking shoes: Better than flip-flops for town walks, paved viewpoints, and days that involve more than sand.
• Sandals with grip: Useful near the beach, but choose a pair that doesn't become slippery when wet.
• Sun protection: A hat, sunglasses, and sunscreen belong in your bag even if clouds are in the forecast.
• A small day bag: Carry drinking water, a dry layer, and a safe place for your phone if rain starts.

Do you need a raincoat or an umbrella?

I'd take a lightweight rain jacket before a bulky umbrella. It's easier to use when you're walking, your hands stay free, and you won't have to worry as much about a gust of wind. For quick trips around town, a compact umbrella is still fine. The best option is the one you'll actually carry.

Don't pack heavy waterproof boots unless your planned activities call for them. They take up luggage space and may feel uncomfortable on warm days. For muddy or remote trails, check local trail guidance and bring appropriate footwear instead of relying on regular beach sandals.

What should you wear for dinner and evening walks?

Relaxed, neat clothes generally work for casual vacation meals. If you've booked a dressier restaurant, check its dress code before you leave home. A lightweight top layer helps if there's an ocean breeze. You won't want to carry a heavy coat around town, but you may appreciate something warmer than a tank top.

What is the best time of day to explore Hawaii in December?

For outdoor activities, I like having the important stuff planned earlier in the day. That isn't a claim that Hawaiian mornings are always sunnier. It's a practical scheduling trick: if weather disrupts your plan, you have time to switch activities, move a reservation if allowed, or try a different beach later.

Use the current local forecast rather than making rules from monthly averages. If the forecast shows the clearest window in the afternoon, take it. If a trail looks wet or a coastal activity has a safety warning, don't push ahead just because it's at the top of your itinerary.

Should you book outdoor activities in the morning?

Morning bookings can be convenient for busy sightseeing days, especially if you want unhurried afternoons. But the best departure time depends on the activity, the operator, and the conditions. Ask guides how they handle rain, surf, and visibility. A responsible operator may move or cancel a trip when conditions aren't right.

Build breathing room between reservations. A long drive, a surprise shower, or a stop at a viewpoint can make a packed schedule feel stressful. Hawaii is too far to travel just to spend every day watching the clock.

What can you do in Hawaii when it rains in December?

Rain doesn't have to be a wasted vacation day. On Oahu, you can plan a museum visit, explore local food spots, browse shops, or spend time at cultural attractions that offer indoor spaces. If showers are light and local conditions are safe, an easy town walk may still be pleasant with a rain jacket.

Save the most weather-sensitive plans, such as exposed coastal walks, viewpoints with little visibility, or ocean excursions, for better conditions. Never treat flash-flood warnings or dangerous surf as minor inconveniences. Check the National Weather Service Honolulu FAQ for background on how changeable Hawaii's winter weather can be, and follow current alerts when you're there.

How do you make a rainy-day backup plan?

Before you travel, save a small set of indoor options near your hotel. Include a place for lunch, a cultural attraction, and something relaxing that doesn't require a long drive. When a rainy morning arrives, you can make a decision over breakfast instead of searching your phone while the rest of your group gets impatient.

Also check opening hours, ticket rules, and holiday closures directly with each attraction. Don't assume an indoor place will be open just because the weather is bad. If you keep your plans loose, a change of scenery can become a good part of the day rather than a disappointment.

Is Hawaii crowded or expensive in December?

December can be a popular time to travel, especially around school breaks and year-end holidays. That can mean less choice for flights, hotels, rental cars, and high-demand activities. Prices and availability depend on the dates and property, so compare actual booking options rather than trusting a broad claim that the entire month is expensive.

If you want the holiday atmosphere, that energy may be part of the appeal. If your idea of paradise includes quiet restaurants and spontaneous hotel choices, the holiday period might not be your favorite time. Being flexible about your travel dates and neighborhood can help you find a better fit.

What should you book early for a December Hawaii trip?

Start with flights and lodging, particularly if your schedule lines up with major holiday travel. Then decide whether you truly need a rental car for your itinerary. Reserve must-do tours, popular dinners, and any activity with limited spots once you're comfortable with the cancellation terms.

Don't prepay for every outing. Keep some free time so you can react to the weather and to what you discover after arriving. If an activity depends on calm seas or a clear view, a flexible booking can be more valuable than locking in the earliest deal.

What mistakes do visitors make when planning December?

• Using Honolulu weather for every island: It doesn't represent all coasts, mountains, or resort areas.
• Assuming rainy days mean washouts: Rainfall timing and intensity vary, and the averages can't predict your specific day.
• Ignoring beach safety: Warm weather isn't proof that surf and currents are safe.
• Booking every day solid: A rigid schedule makes a short shower feel much more disruptive.
• Skipping a light layer: Even comfortable coastal evenings can feel cool after a swim or in the wind.
• Leaving holiday reservations too late: Less availability can force expensive or inconvenient compromises.

Who should skip Hawaii in December?

If you need reliably hot, cloudless beach weather every day, I wouldn't sell you December Hawaii as a sure thing. Honolulu is pleasantly warm on average, but December is its wettest month in the supplied data. Someone planning an expensive, beach-only vacation with no tolerance for rain may be happier considering a different time or comparing other warm-weather destinations.

I'd also think carefully before choosing December if rough surf would prevent you from enjoying the activities you care about most, if you dislike busy holiday travel, or if your budget leaves no room for flexible reservations. These aren't reasons that everyone should avoid Hawaii. They're reasons to match the destination to the trip you actually want.

If you're mainly escaping freezing weather, want a mix of city and beach experiences, and can handle changing plans when it showers, Honolulu in December is a strong option. The average high of 77.7°F is comfortable, and the combination of outdoor and indoor possibilities makes it easier to have a good day even when the sky isn't perfect.

How can you plan a better Hawaii trip in December?

Choose your island for the experiences that matter most, then choose your hotel area with the windward and leeward pattern in mind. Compare Honolulu's monthly averages only with other Honolulu averages. Look at the latest forecast closer to departure, check local safety alerts while traveling, and keep your outdoor reservations flexible when possible.

Here's the approach I'd use: pick the activities you absolutely don't want to miss, leave open space around them, and plan a few indoor alternatives near your base. Check the cancellation policy before paying for weather-dependent tours. Keep a light jacket, comfortable shoes, and sun protection ready so a small weather change doesn't require a trip back to the room.

You can organize destinations and activity ideas with the WeatherApex trip planner. And if you're still comparing your winter getaway choices, look at other places that are warm in December or what December feels like in Florida before booking flights.

The takeaway is simple. December in Honolulu isn't a guaranteed sun-soaked escape, and pretending otherwise won't help you plan. But if you're comfortable with some rain, realistic about ocean conditions, and willing to adjust a beach day when needed, it can be a genuinely enjoyable time to visit Hawaii.
