12 Best Places to Visit in the US, Each Matched to Its Best Month

If we had to name the best places to visit in the US and pin each one to its right month, the list would start with New York in September, Washington DC in April, New Orleans in March, San Diego almost any time and Honolulu all year. Timing changes everything here: Las Vegas averages a pleasant 70.0°F (21.1°C) in March and a brutal 103.8°F (39.9°C) in July, and Seattle goes from 4 rainy days in July to 18 in November.

So this is not a list of places in a vacuum. It is twelve cities, each paired with the months when its weather actually works, plus an honest note on when to stay away. Every number comes from WeatherApex 20-year averages for the named city. Where we mention nearby parks or regions, the figures still belong to the city, and we say so.

Best Places to Visit in the US: The Quick Answer

The Northeast: Big Cities with Real Seasons

New York City

New York belongs on any list of the best places to visit in the US, and it is also the city where the month matters most for comfort. September averages 75.9°F (24.4°C) with 9 rainy days, and the heavy July humidity has usually eased. Winter is cold, with January lows of 25.2°F (-3.8°C), but it is also the cheapest season for hotels and theater. We wrote a full month by month breakdown in our best time to visit New York guide.

Washington DC

The capital is best in spring. April averages 66.4°F (19.1°C) with a low of 46.2°F (7.9°C), and the cherry trees around the Tidal Basin usually bloom in late March or early April. That is also when crowds peak, so book early or aim for mid April when the petals are gone but the weather holds. October is the quieter alternative at 68.0°F (20.0°C). Skip July if you can: 88.5°F (31.4°C), 13 rainy days and thick humidity make walking the National Mall hard work. See Washington DC in April.

Boston

Boston is a walking city, and its walking season is short. September is the sweet spot at 73.6°F (23.1°C), and October, at 62.4°F (16.9°C), brings the leaves and the best day trips into New England. Winter is the hard part: January averages 36.3°F (2.4°C) with a low of 21.2°F (-6.0°C), and snow is routine.

The Middle: Chicago and the Music Cities

Chicago

Chicago in summer is one of the great American city experiences: beaches on the lake, outdoor festivals, architecture cruises on the river. June averages 76.1°F (24.5°C) and September 72.7°F (22.6°C) with just 9 rainy days. Winter is a different story, with a January high of 31.1°F (-0.5°C) and lows near 19.4°F (-7.0°C), plus wind off the lake. Our best time to visit Chicago guide goes deeper.

Nashville

You can hear live music in Nashville any night of the year, so the question is purely about comfort. April averages 69.6°F (20.9°C) and October 71.6°F (22.0°C), with 9 rainy days in October, tied with September for the fewest of the year. Summer is hot and stormy: July reaches 89.1°F (31.7°C) with 15 rainy days. Nashville is rainy more often than people expect, with 9 to 15 rainy days every month.

The South: New Orleans and Key West

New Orleans

New Orleans has a short perfect season and a long sticky one. March averages 70.5°F (21.4°C) and April 76.3°F (24.6°C), which is festival time: Mardi Gras usually falls in February or early March, and the big spring music festivals follow. November is excellent too, at 69.1°F (20.6°C) with 8 rainy days.

From June to September the city turns into a steam room. July has 20 rainy days and 80% humidity, and August gets 7.8 inches (198 mm) of rain. Hurricane season runs June 1 to November 30, with the Gulf most active in late summer. We would not go in August. The New Orleans March weather page is the one to check.

Key West

Key West is the closest thing the mainland US has to a tropical island in winter. January averages 72.7°F (22.6°C) with a low of 68.7°F (20.4°C), and March climbs to 74.8°F (23.8°C) with only 4 rainy days and 11.0 hours of sun. That is peak season, with prices to match. Late summer is hot, wet and in the hurricane zone: September has 18 rainy days and 5.4 inches (137 mm) of rain. For more detail, read our Key West weather in January article.

The West: Desert, Coast and Rain Forest

Las Vegas and the desert parks

Vegas works best as a base for the desert in spring and fall. March averages 70.0°F (21.1°C), April 79.0°F (26.1°C) and October 80.2°F (26.8°C), all ideal for day trips to the canyons and red rock parks of Nevada, Utah and Arizona. We do not have figures for those parks, and the higher ones run noticeably cooler than the city, so pack a layer.

Summer is extreme. July averages 103.8°F (39.9°C) and nights stay at 80.8°F (27.1°C). The Strip is air conditioned end to end, so a casino weekend is doable, but hiking in that heat is risky. For outfits, see what to wear in Vegas, and for the October numbers, Las Vegas in October.

San Diego

San Diego has the steadiest weather on this list. The average high stays between 63.7°F (17.6°C) and 77.7°F (25.4°C) all year, and from June to September it averages 0 or 1 rainy days a month. Late summer and early fall are the warmest, with September at 77.5°F (25.3°C), and the ocean is at its warmest too. May and June often bring a gray marine layer in the mornings along the coast, which the numbers do not fully show. Details on the San Diego September weather page.

San Francisco

San Francisco flips the usual calendar. Its warmest month is September, at 71.2°F (21.8°C), not July, which averages 68.2°F (20.1°C) and is often foggy and windy by the water. Visitors who arrive in July in shorts learn this fast. September and October are dry and clear, and winter brings most of the rain: December averages 4.2 inches (107 mm) over 10 days. The same split between coast and inland shows up all over the state, which is why our best time to visit California guide treats each city separately.

Seattle

Of all the best places to visit in the US, Seattle is the one with the simplest answer: go in July or August. July averages 75.9°F (24.4°C) with 4 rainy days and only 0.7 inches (18 mm) of rain, and the long evenings are perfect for ferries, the islands and mountain day trips. From October to March, the city lives up to its reputation. November gets 7.5 inches (190 mm) over 18 rainy days, and December averages just 3.9 hours of sun a day.

Hawaii and Alaska: The Two Outliers

Honolulu

Honolulu is the safe choice for warm weather in any month. Highs range from 76.1°F (24.5°C) in February to 83.1°F (28.4°C) in August and September, and the driest month, June, sees just 0.8 inches (20 mm) of rain. Winter has a few more showers and big surf on north facing shores. The shoulder months of April to June and September to October are usually cheaper and less crowded than Christmas or summer holidays. Our best time to visit Hawaii guide covers the other islands.

Anchorage

Alaska only really works for most visitors from June to August. Anchorage peaks at 64.8°F (18.2°C) in July, while December gets just 1.7 hours of sun a day. Rain builds quickly after midsummer, with 17 rainy days in August. If Alaska is on your list, read the best time to visit Alaska guide before booking.

Where Not to Go, and When

• Las Vegas in July and August: 101.3°F to 103.8°F (38.5°C to 39.9°C) highs. Fine indoors, dangerous on trails.
• New Orleans in August: 88.0°F (31.1°C), 80% humidity and the wettest month of the year.
• Seattle in November and December: 18 rainy days each and short, dark days.
• Chicago and Boston in January: highs barely above freezing or below it.
• Key West in September: peak hurricane risk and the most rainy days of its year.

Matching the Place to the Trip

For a first big US trip: New York in September, then fly west to San Francisco and San Diego, which are at or near their warmest and driest at the same time.

For winter sun: Key West, Honolulu and San Diego. Key West has the warmest January nights of the mainland cities we track, with a low of 68.7°F (20.4°C).

For families: San Diego in summer is hard to beat, with highs from 71.8°F to 77.7°F (22.1°C to 25.4°C) between June and August and almost no rain. Honolulu works too, if the budget allows.

For music and food: New Orleans in spring or November, Nashville in April or October.

For the outdoors: Seattle in July and August for mountains and water, Las Vegas in March, April or October for the desert.

How We Chose These Twelve

To build this list of the best places to visit in the US, we started from the US cities in the WeatherApex dataset and picked the ones most visitors actually travel to, then looked for each city's most reliable window using 20-year averages from 2006 to 2025, drawn from the Open-Meteo historical archive. These are typical conditions, not a forecast, and a single heat wave or storm can upend a week. Numbers apply to the city itself, not the surrounding region, so desert parks, mountain towns and the far side of an island can differ a lot. When you have dates, compare a few of these cities side by side in our trip planner.

One last booking tip: the best months on this list are also the busiest. If a place you want peaks in a holiday week, shift a few days earlier or later. In most of these cities the weather a week either side is nearly identical, and the hotel bill is not.
