What May feels like in Castries
As a tropical city, Castries is warm all year; May is not part of a clear dry or wet season. The midday hours are hot; shade and water matter on long walks. The gap between afternoon and night is small, so nights stay warm and the temperature hardly changes after dark. The air is muggy, so it feels hotter than the thermometer suggests.
