The highest temperature ever registered during this month on the island is 33°C, whilst the lowest temperature ever registered here at this time of year is 17°C.

Because March in St Lucia is fairly cool, compared to the rest of the year, it's a good time for travellers who aren't keen on high temperatures to visit. On the other hand, if you love the sun and want to experience St Lucia at its warmest, you're best off forgetting about March and visiting in August or October, when temperatures are usually at their highest. However, if you do choose to visit St Lucia in March, you'll need to pack plenty of light and airy clothing, suntan cream and an umbrella to protect you from the elements.


Throughout the month, St Lucia is subject to an average of 27mm/1 inch of rainfall spread out between 16 wet days that's almost have the precipitation received in February.

Here guests can choose between studios, one-, three-, four- and five-bedroom apartments, each of which includes air conditioning and private bathroom. Because of the low rates, amenities and services are limited to restaurant with free WiFi access, excursion booking and spa which offers facials, massages and body scrubs.

St Lucia Beach for March

When it comes to beaches ideal for snorkeling, Jalousie Beach should definitely be at the top of your list. The waters in the designated snorkeling area are very calm, shallow and clear, creating the ideal environment for admiring the tropical fish and rock formations under the water's surface. Although most of the beach is reserved by the onsite hotel, the sun loungers and shades by the snorkeling zone aren't owned by the hotel and are free for everyone to use. Other water sports, including windsurfing and small pedalo-like boats, are available, as well as water taxis to take you to nearby beaches and a beach-side restaurant.

The beach at Anse La Raye is an authentic fishing village beach. Surrounded by a small promenade lined with restaurants serving fresh fish, seafood and drinks, this beach isn't one of the most beautiful on the island, but it has a lot of character. There is a small stretch of golden sand available for sunbathing, but no sun loungers or parasols, so you'll need to bring your own. The sea is warm and calm, making it safe for swimming, as long as you keep an eye out for the fishing boats which regularly moor up on the shore.

Bars and Restaurants

Dragonfly situated inside the Windjammer Landing hotel is one of the best places to sample authentic Caribbean cuisine in luxury surroundings. This eatery is open for dinner from 6.30pm until 10pm every night, except Tuesdays and Fridays, and reservations are required. Tuesdays and Fridays are reserved for themed buffet events, which are also worth a try. Classic starters such as callaloo soup and salt fish accras, mains such as jerk sausage and Caribbean beef, and desserts such as banana crumble and rum and fruit cake all feature on the menu.

Tucked into Rodney Bay, Bosun's Bar & Bistro is perfect for diners who want to enjoy sea views whilst they eat. This restaurant is open from 7am until 11pm for breakfast, lunch and dinner, with the bar staying open even longer. The breakfast and lunch menu offers sandwiches, baguettes, paninis, soups and salads, whilst the evening menu offers more filling and sophisticated French-inspired starters, mains and desserts.

If you're partial to a drop of rum, make sure you visit the Rum Therapy Bar and Treatment Centre. Located in Castries, this bar serves up a selection of straight rums, rum-based cocktails, beers and beer buckets. Although the drinks are sublime, the entertainment is even better and takes the form of live bands, local singers and karaoke. The bar is only a tiny wooden shack and since it's found close to where the cruise ships dock, it can get full when the cruise ships are in port.

For something more glamorous, enjoy a drink at Le Mistral Lounge. Found inside the Royal by Rex Resorts hotel, this bar overlooks the Reduit Beach and offers great views over to Pigeon Island. Here you can enjoy local and international spirits, cocktails, wines and beers, alongside live entertainment which changes regularly. The bar is open every night from 6pm until 1am and smoking is not permitted.

Things to do in St Lucia in March

Morne Coubaril Estate is the place to go for an action-packed day out. Here you can explore a plantation which produces coffee, cocoa, copra and tropical fruits, such as limes, grapefruits, oranges and coconuts the last of which are used to bake cakes available at the onsite restaurant and gift shop. For something more exciting, you can have a go at zip lining during your visit, too. The Morne Coubaril Estate offers eight zip lines which will see you flying through tropical vegetation at speeds of up to 30mph. Photos are taken during the activity which you can buy for a fun and memorable souvenir.

Located in Soufriere, the Church of the Assumption of the Blessed Virgin Mary is one of the most visited religious buildings on the island. The outside of the church features a gothic design, with lots of sharp points and dark grey and blue paint. The inside of the church is a much more colourful affair, with rich mahogany pews, light blue pillars, colourful religious statues and several large windows at the top of the building, allowing the light to stream in. Most tourists visit the church for the opportunity to join in with one of the sermons, during which Creole and English Catholics come together to sing hymns in a joyful, upbeat manner.

For a once-in-a-lifetime experience, sign up for an excursion with the Holiday Riding Stables. There are four different tours available, providing something for all ages and abilities. The one-hour trail ride takes you along Cas-En-Bas beach and is perfect for those with no experience, whilst the two-hour trail ride goes to the same beach but also includes riding the horses in the sea. The sunset beach ride is equally suitable for couples in search of a romantic experience and groups on the lookout for photo opportunities, whilst the ride in the ring option is perfect for small children and young riders, since the horses never leave the ring, making it as safe as possible.
