High season in Saint Barthelemy: climate, crowds and tips for making the most of it
Discover why high season is not the hottest period, but the most pleasant to visit St. Barts
Understanding what high season in Saint Barthelemy really is
High season in Saint Barthelemy is not the hottest period of the year. It is primarily the period of highest tourist traffic, which coincides with winter months in the northern hemisphere.
Why so many visitors in winter?
While North America and Europe experience their coldest months, Saint Barthelemy offers an ideal climate characterized by:
- Generous sunshine with bright and clear days
- Pleasant temperatures between 26°C and 28°C, never stifling
- Little precipitation, the dry season is in full swing
- Stable and predictable weather thanks to constant trade winds
Travelers don't come seeking extreme heat, but rather to escape the winter cold while enjoying a balanced tropical climate. This period also coincides with year-end holidays (Christmas, New Year), which reinforces the island's appeal for sunny and festive vacations.
Key point to remember
High season corresponds to a perfect balance between pleasant climate, stable weather and lively social life. It's the very image of Saint Barthelemy: luxury, sunshine and good living at the heart of winter.

Why is it less hot than summer during high season?
Understanding the meteorological phenomena that make this period so pleasant
The trade winds are regular winds blowing from the northeast during high season. Contrary to popular belief, these winds are not unpleasant: they constantly refresh the atmosphere and make the ambient temperature very pleasant, even in full sun.
These winds create a natural sensation of freshness that prevents any feeling of stuffiness. This is what fundamentally differentiates high season (Caribbean winter) from low season (hotter and more humid tropical summer).
During high season, humidity levels are significantly lower than in summer (about 68-70% versus 75-80% in August-September). This difference may seem minimal, but it radically changes the perception of temperature.
With less humidity in the air, the heat is much more bearable and perspiration evaporates more easily, providing a feeling of comfort even on the sunniest days.
One of the most pleasant aspects of high season: nights are truly cool. Temperature can drop to 22°C at night, which contrasts sharply with the stifling nights of tropical summer (26-27°C).
Practical tip
In the evening and early morning, some people who feel the cold easily may feel a bit chilly, especially with the wind. A light cardigan or jacket can be useful for terrace dinners or evenings by the sea. This "coolness" is very appreciated after a day in the sun!

Practical tips for enjoying high season
Essential list to prepare your stay and avoid inconveniences
Even though the temperature is mild, the UV index remains very high. Apply high protection sunscreen regularly, especially between 11am and 3pm. The wind can give a false sense of coolness.
The best restaurants are fully booked several days, even weeks in advance during high season. Book as soon as possible, ideally before arriving on the island.
Plan your trips ahead, especially to popular beaches. Leave early in the morning (before 9am) to easily find a parking spot. Avoid peak hours (12pm-2pm).
If you haven't booked in time, go through local concierge services who often have access to privileged time slots through their network. Don't rely solely on luck.
Even during high season, monitor sargassum arrivals which can affect some beaches. Check local weather sites or ask your accommodation before heading out.
Choose your accommodation based on proximity to your favorite beach, wind exposure and sun orientation. Some neighborhoods are windier or shadier than others.
