The best time to visit L'Appelle is during the dry season, which runs from December to May.
During these months, you can expect sunny days, lower humidity, and a comfortable average temperature of around 80°F (27°C). This period is ideal for enjoying the island's many outdoor activities, such as exploring the beaches, snorkeling, and sailing, without the interruption of rain.
For travelers looking for the calmest seas and consistently clear skies, the months of March and April are particularly favorable. This is when the weather is at its most stable, making it superb for water sports and island hopping to nearby Petite Martinique.
While the wet season (June to November) offers lush landscapes and fewer crowds, it also brings a higher chance of rain showers and the possibility of tropical storms, especially from August to October.
