St Martin Weather

This beautiful Caribbean island is perfect to visit all year round, making it a very desirable holiday destination. St Maarten / St Martin weather offers visitors endless hot sunny days, with warm evenings and the occasional refreshing shower in between. St Martin is known for its stunning volcanic and mountainous appearance. Like most other islands in the Caribbean, Saint Martin has a tropical climate, which naturally creates a diverse and interesting landscape.

Some of the coastline, particularly on the west coast where showers are less common, is rugged with dry vegetation and almost desert like in places. The east coast, on the other hand, where the gentle warmth of the trade winds meet the mountains, condense and turn into warm showers of rain, has plenty of lush, green plants and trees.

St Martin weather and its climate as a whole is wonderful all year round. The average annual temperature is 80F, but can get as high as 91F during certain times of the year. Rest assured that the temperatures rarely ever dip below 68F so you certainly don’t need to worry about feeling too cool any time of the year. Needing a light jumper for those cooler temperatures is about the height of it. St Martin is blessed with a stable temperature year round thanks to the trade winds, and there is no rainy season as such. You may encounter the odd shower or two at times but more often than not they are short lived.

Seasons

There are still two seasons on the island though; the dry season from December to April, and the more wintry season which is experienced from May to November. The dry season mirrors the busiest tourist season on St Martin making it a very popular time for holiday makers to descend on the island. During the dry season visitors are greeted each day with cool mornings and the night time temperatures can dip as low as 68F, but throughout the day you will often be basking in at least 81F. From May to November the temperatures are generally higher throughout the day.

Compared with other neighbouring islands further south, such as Guadeloupe and Martinique, St Martin doesn’t notice such a difference between the two seasons as far as the rains are concerned. The rainy, more wintery season, is generally associated with the hurricane season, which runs from June to December. This is obviously something to be aware of if you are choosing to travel to St Martin’s over this period, however, the last major hurricanes recorded were Hurricane Luis in 1995, and Jose and Lenny in 1999.
