Climate of Saint Kitts and Nevis
Country climate guideSaint Kitts and Nevis is a federation of two volcanic islands in the Leeward Islands of the northern Caribbean, separated by a strait only about three kilometres wide. Both are small, altogether little more than 260 square kilometres of high, mountainous land, and the climate is tropical with a marked wet and dry season. Basseterre, the capital on Saint Kitts, averages about 25 °C in January and around 27 °C in July, with roughly 1,500 millimetres of rain a year.
Main climate types
The official classification is tropical rainforest or monsoon, but the trade wind does most of the work. The south-west, windward coasts of both islands, where the mountains rise straight out of the sea, are the wet side: the south of Saint Kitts and of Nevis receive well over 2,000 millimetres a year. The sheltered north-west, leeward coasts, including Basseterre, get about 1,200 to 1,500 millimetres. There is no cold season.
Temperatures
Monthly means sit in a narrow band of roughly 25 °C to 28 °C all year. January to March are coolest, with coastal lows near 20 °C and highs in the high 20s °C, while July to October are warmest and most humid. Because the land is steep, coast and hilltops differ by several degrees; on the rim of Mount Liamuiga, about 1,150 metres up, it is several degrees cooler with frequent cloud.
Rainfall
Most rain falls from about May or June to November, driven by the trade wind and by convection, arriving as heavy afternoon showers rather than long drizzle. January to April are driest, though showers still blow through. The islands lie in the path of the Atlantic hurricane season, which peaks between August and October, and storm surge and wind can cause serious damage on the exposed coasts.
When to go
The dry season, January to April or May, is the best for beaches, hiking and diving, with lower humidity and steady trade winds. May and June are warm and usually pleasant, with fewer crowds than the winter peak. Between August and October hurricane risk peaks and prices fall, so travellers should hold insurance covering storm disruption and check the forecast before island-hopping connections.
