Saint Kitts and Nevis islands (officially St Christopher and St Nevis) are part of the Leeward islands in the northern Lesser Antilles in the Caribbean Sea. Although both of these Caribbean islands are small, St Kitts island is nearly twice the size of Nevis.
Tourism peaks in the winter and spring months, which are some of the most beautiful times of the year for Saint Kitts and Nevis. To be quite honest, though, the weather is nearly perfect all year. The average high temperature ranges from 81°F (27°C) in the winter months to 85°F (29°C) during the summer.
The islands see northeastern trade winds, which can help cool you down on the hotter days. Late August and September are usually the windiest time periods. Low humidity means even the hottest of days are more than bearable. The weather in the islands is similar throughout, although higher elevations like the dormant volcano, Mount Liamuiga in the center of St Kitts island, may experience slightly cooler weather.
On average, Nevis sees an average of approximately 55 inches of rain per year while St Kitts only averages about 48 inches of rain. The months with most rain are late summer and fall, which, not surprisingly, correspond with hurricane season. Saint Kitts and Nevis do lie in the Atlantic hurricane zone, where fierce storms may develop between August through November, and Saint Kitts and Nevis weather is affected once every 3 years or so on average by a tropical storm system, with a direct hurricane hit happening ever 12 years (give or take a year).
The beautiful and consistent St Kitts weather makes the Caribbean islands of Saint Kitts and Nevis a must visit destination all year round.
