St Kitts and Nevis climate overview

This tiny duel-island nation lies in the north of the eastern Caribbean island chain. Both the French and the British fought over the islands for centuries, but today they exist as an independent country within the British Commonwealth. Tourism revenue is becoming increasingly important, but agriculture and light industry remain the backbone of the country's economy.

Both St Kitts and Nevis are dormant volcanoes that support lush tropical rainforest. However much of the lower slopes have now been cleared to make way for extensive sugarcane plantations, particularly on St Kitts. In contrast, the southeast peninsula of St Kitts is uninhabited with fine beaches and desert-like vegetation of cacti and yucca.

The largest colonial fort in the Caribbean can be found on top of Brimstone Hill on St Kitts. Major restoration work has returned it to its former glory and today it nestles amongst a rolling landscape of rainforest.

St Kitts and Nevis has a tropical climate with rainfall throughout the year, and the heaviest rainfall occurs inland over the mountains from July to November. February to June are drier and sunnier months, although even during this period, there will still be a few showers, particularly over the mountains.

Temperatures remain warm all year round with little seasonal variation. The coasts are usually a couple of degrees warmer than the mountains with the west coast having the best of the sunshine. Hurricanes are possible anytime from June to November.
