St. Lucia

St. Lucia is an island in the eastern Caribbean Sea on the Atlantic Ocean border. Known for its volcanic beaches, luxury resorts and tropical climate, it’s a great year-round holiday destination.

The Piton Mountains are dramatically tapered and offer some shade to the surrounding resorts from the heavy rainfall and strong winds seen during the wet season. The best time to visit St. Lucia for heat is from mid-August to the end of October when temperatures rarely fall below 31°C.

High humidity is a regular occurrence in St. Lucia, but the north-eastern trade winds help to control levels from reaching uncomfortable levels.

The best time to go to St. Lucia for the most sunshine as possible is during March. It tends to be the sunniest time of year, with over ten hours of sunlight per day.

The surrounding waters are usually very mild by nature, ranging from 27°C to 29°C. This is perfect conditions for swimming and taking part in water sports like snorkelling, wind surfing and scuba diving.
