St Lucia weather overview

St Lucia, one of the Windward Islands, is large and mountainous with volcanic peaks. It attracts more rain than is normal tor the Caribbean. This falls mainly from May to January and is most intense during the July to November hurricane season when tropical storms can make life difficult even if they don't hit the island directly.

The west coast (where Castries is located) is more sheltered from the prevailing winds. Temperatures on St Lucia are high throughout the year but rarely unbearable since sea breezes help dissipate the humidity, although nights can be sticky.

What to pack for St Lucia weather

Light cotton clothing is appropriate, and be prepared for rain at any time of the year.
