Low season in Saint Barthelemy: climate, advantages and tropical authenticity

The warmest period of the year, but also the most authentic: discover St. Barts away from the crowds, with attractive rates and lush nature.

Low season does not mean bad season

Contrary to what its name might suggest, the low season in Saint Barthelemy is not a period to avoid. It is simply the period of lowest tourist traffic, which extends from May to November.

In reality, it is during the low season that St. Barts experiences its highest temperatures. Tropical heat sets in, the sea reaches its maximum temperature (up to 29°C), and the vegetation becomes lush thanks to short but regular tropical rains.

Key takeaway: the low season corresponds to the tropical summer of Saint Barthelemy. It is an ideal period for those seeking intense heat, authenticity and more affordable rates.

Why is it hotter during the low season?

Several meteorological factors explain why the low season is the warmest period of the year in Saint Barthelemy:

Weakened trade winds

The trade winds, which naturally cool the island during high season, are much less present from May to November. The air is therefore less circulated, which accentuates the heat sensation.

High humidity

The humidity level increases significantly (70-77%), which amplifies the muggy heat feeling typical of tropical climates. Perspiration evaporates less quickly, making the heat more perceptible.

Sun position

The sun is higher in the sky during the tropical summer, which intensifies solar radiation. Days are long and sunshine remains generous despite the showers.

Important: Even if the displayed temperature does not exceed 32°C, the actual heat sensation can be much higher due to humidity and lack of wind. This is what fundamentally differentiates the low season climate.
