Saint Lucia Weather and Climate

General & Geography

According to COUNTRYAAH, St. Lucia (English: Saint Lucia) is an island state in the Lesser Antilles in the Caribbean. The island was under the colonial rule of the British Crown for a long time, only in 1966 did Saint Lucia receive the status of an autonomous state. The country has been an independent member of the Commonwealth of Nations since 1979.

The head of state is the British Queen Elizabeth II, represented by a local governor general. The official language is still English today, which makes communication very easy for tourists on St. Lucia.

The area of ​​the Caribbean state is only about 616 square kilometers, on which about 170,000 people are at home. Castries on the northwest coast is the capital of Saint Lucia.

In addition to an important port for export goods such as bananas, sugar cane, rum, tropical fruits and cocoa, Castries is also home to George FL Charles Airport for intra-Caribbean flights.

Tourists from Europe mostly land at the larger Saint Lucia Airport Hewanorra International in the south of the island. This is served by Air Canada, American Airlines and British Airways via London. In the winter flight schedule, Condor usually offers direct flights from Frankfurt am Main to St. Lucia once a week.

The flight time without a stopover is around 9.5 hours. Alternatively, the journey can also be made by express ferry or fast catamaran via the neighboring islands of Martinique, Guadeloupe and Dominica.

Climate on Saint Lucia

St. Lucia has a humid tropical climate with regional differences, which result mainly from the large lava fields and mountain ranges in the interior of the island. The generally rather hot climate is cooled down a bit by the northeast trade wind, so that the temperatures are usually bearable.

The elevations, above all Mount Gimmie with a height of 960 meters and the volcanic mountain cones Gros Piton and Petit Piton, ensure that cloud formations can rain down on Saint Lucia all year round. Nevertheless, a dry season and a rainy season on the island can also be statistically proven: especially between June and November, significantly increased amounts of precipitation can be found on St. Lucia, even if it is usually only very short and strong tropical showers. This warmer rainy season largely coincides with the hurricane season in the Caribbean and has a noticeably higher humidity.

When is the best time to visit St. Lucia?

In general, Saint Lucia is suitable for a holiday all year round with some restrictions, although the weather can sometimes be quite inconsistent, especially during the rainy and hurricane seasons. However, the dry season is particularly suitable for beach holidays and outdoor activities such as trekking or water sports.

We therefore recommend the period from mid- December to mid- May as the best travel time for Saint Lucia. The months of January, February and March are particularly attractive. However, this is also the absolute high season with correspondingly high prices and visitor numbers on the island.

From around mid- April, attractive discounts in the off-season and May is usually still a good time to travel to St Lucia. From mid-May, however, the beginning of the rainy season is usually clearly noticeable, the humidity rises and there are heavy showers on many days.

Sightseeing on Saint Lucia

The greatest attraction of the Caribbean island of St. Lucia is, above all, its unique natural setting with breathtaking mountain panoramas, lush rainforests and romantic bays. The landmarks of Saint Lucia are the twin pitons towering 800 meters into the sky not far from the Jalousie Plantation harbor.

The capital Castries is one of the most beautiful spots in the entire Caribbean, especially the beautiful harbor is always worth a visit. The ruins of the old fort at Morne Fortune provide a breathtaking view. In the city center itself, many colonial buildings fell victim to a major fire in 1948, and the preserved buildings around Derek Walcott Square still give a good insight today.

It’s always colorful on Fridays at the Jump Up street party in the fishing village of Gros Islet, where local delicacies and lots of Caribbean joie de vivre await. In Anse La Raye the BBQ night attracts with live music and delicious fish dishes on the same day. A visit to Marigot Bay should not be missing on a trip to Saint Lucia, nor should a mud bath in the sulfur springs near Soufrière.
