Pristine beaches, lush rainforests, iconic Pitons – St Lucia is a tropical haven inviting you to soak in its glorious sun, indulge in its mouthwatering cuisine and embrace its rich cultural heritage.

The island nation in the Caribbean is a popular place for travellers thanks to its year-round hot weather. No matter what time of year you visit, you can enjoy a luxurious holiday.

But when is the best time to visit St Lucia?

Discover our guide on what time of year to go, when the best St Lucia weather is and why you should travel during peak and off-peak seasons.

When is the best time to visit St Lucia?

The best time to go to St Lucia is from February to May, during the dry season.

Dry season is a period of dry weather, averaging temperatures of 30°C. During the latter months, you’ll have the best conditions for a relaxing beach break, with minimal rainfall and sunnier days. So, relax on the sands or head out on the water for a private cruise. The sun kisses the shores for an average of seven hours a day, giving you enough time to enjoy the idyllic island.

This peak season is the busiest time of year. Many people aim to book their holidays during this period, making the most of the weather and enjoying its outdoor experiences. On the other hand, the rainy season is a quieter period. You may have a more peaceful holiday, as the crowds tend to avoid the wetter weather. However, this comes in showers which clear quickly.

December to January is also an excellent time for travelling to St Lucia, perfect if you’re looking for a festive Christmas break or simply want to experience some winter sun.

St Lucia weather in February

February is one of the driest months of the year and a very popular time to travel for families, thanks to the half-term break. We recommend you book well in advance. By speaking with our Travel Specialists, we can tailor your trip with bespoke experiences, such as hiking the Pitons!

St Lucia weather in March

Explore the island’s natural wonders in March, making use of the low 42mm of rainfall. Sulphur Springs, known as the Caribbean’s only ‘drive-in volcano’, is a real highlight you can experience on foot or by car. Dive into the mud baths and discover their therapeutic, detoxifying properties.

St Lucia weather in April

April and its rising water temperatures make for a fabulous swimming experience. Alternatively, we recommend spending a day sailing or yachting on the clear blue seas. St Lucia’s range of water-based activities are best enjoyed when the water is at its warmest during this month.

St Lucia weather in May

With lower prices and weather like January and April, May is a great time to travel. It’s best to visit now as humidity levels are at their lowest (75%) before rising in the wet season. St Lucia Jazz & Arts Festival also takes place, with previous performers such as Rihanna and Diana Ross.

St Lucia weather in June

June is the start of the wet season, but rainfall comes in short and sharp bursts. We love this period as you can expect lots of consistent sunshine while the winds take the edge off the heat. So, why not explore the island – from Mount Pimard to Rodney Bay Marina – on a segway tour?

St Lucia weather in July

Make use of the month’s daily eight hours of sunshine by touring the island, taking in such sights as Marigot Bay – where you can spend time indulging in a delicious waterside lunch. Then at sunset, there’s nothing better than sipping a lovingly prepared rum punch on the beach – bliss.

St Lucia weather in August

August is both a hot and sunny month to visit St Lucia. It’s also Chocolate Heritage Month. So, why not book a ‘Tree to Bar Experience’ at the world-renowned Hotel Chocolat? You’ll be able to understand the inner workings of what it takes to turn a cocoa bean into a chocolate dream!

St Lucia weather in September

The hottest month of the year is September at 31.6°C. That’s why we recommend cooling off by diving into the crystal-clear waters and discovering the island’s beautiful marine life. Grab your snorkelling gear and head beneath the surface to see diverse coral and sunken shipwrecks.

St Lucia weather in October

October is the start of whale watching season in St Lucia. The gentle giants migrate to the waters around the island to mate. You can watch the pods from your spacious vessel, observing them as they graciously breech high into the air, all the while soaking in the sun and hot weather.

St Lucia weather in November

Wet season comes to an end in November, and as it’s outside of the school holidays, you can expect lower prices. Not only that, but the temperatures remain high. So, spend time with your family by chartering a sailboat to explore the country’s many welcoming bays and coves.

St Lucia weather in December

December is Christmas time in St Lucia. Enjoy the festive period with a big, traditional St Lucian Christmas dinner and soak in the fine weather. Swapping snow for sandy beaches, Christmas in St Lucia is something every lover of the Caribbean should experience at least once.

Peak times to visit St Lucia

The peak months for St Lucia are between December and May.

Many tourists find this the best time to visit St Lucia due to its dry weather and excellent conditions for water-based activities around the island. Attractions like the Diamond Botanical Gardens, Pigeon Island and Sugar Beach are also busy. But the vibes are cheerful and upbeat.

The heat isn’t unbearable either. Because of the northeasterly trade winds, there’s a constant breeze which makes the weather conditions more comfortable. So, you can go sunbathing on the sun-soaked sands and enjoy a relaxing break of nothing but rest and rejuvenation.

Off-peak times to visit St Lucia

The off-peak months for St Lucia are between June and November.

As more tourists tend to flock to St Lucia’s tropical shores during the dry season, this leaves the off-peak season relatively quiet. Although you may be tempted by peak’s dry conditions for a beach break, the weather in St Lucia during off-peak is still great. When rainfall occurs, it only does so in short, sharp bursts – which has little to no impact on your overall experience.

On top of this, whales flock to St Lucia’s waters to mate in off-peak. You can embark on a whale watching expedition, spending the day searching for and seeing these majestic creatures.
