The "rainy season? on St. Barts is loosely defined as late August through early December, with the highest precipitation, about five inches, occurring in October. However, average precipitation even in the "dry" months of February and March will be nearly two inches, with April and June averaging just over two inches.

The rainy season in St. Barths typically runs from June through November, which coincides with the Atlantic hurricane season. During this time, the island experiences higher humidity and more frequent tropical showers. However, these are often "passing showers"—short, intense bursts of rain followed by bright sunshine—rather than all-day washouts. The months of September and October generally see the highest rainfall and the greatest risk of tropical storms, making this the "low season" for tourism when many hotels and restaurants close for maintenance. In contrast, the "dry season" runs from December through May, which is the peak tourist window. Even in the dry season, you might see a few minutes of rain in the morning, but the lush, green hills of the island depend on those passing clouds to maintain their tropical beauty throughout the year.

Excellent question! The weather in St. Barthélemy (St. Barths) is fantastic year-round, but it does have a distinct wetter period.

The rainy season in St. Barths typically runs from August to November.

This period coincides with the Atlantic hurricane season, which officially lasts from June 1 to November 30, with the peak activity usually from mid-August to mid-October.

Here’s a more detailed breakdown:

• Wettest Months: September and October are historically the rainiest and most humid months. This is when the island is most likely to experience tropical waves, storms, or hurricanes.
• Shoulder Months: August and November see increased rainfall compared to the dry season, but it’s often in the form of short, heavy afternoon showers that clear quickly, rather than all-day rain.
• Dry Season: December to April is the classic dry, high season with minimal rain, lower humidity, and steady trade winds. May through July is also generally dry, with a gradual increase in humidity and a small chance of brief showers.

Important Nuances for Travelers:

1. “Rainy” is Relative: Even during the rainy season, St. Barths enjoys a lot of sunshine. Rain showers are often intense but brief, followed by clear skies. It’s rare to have several consecutive days of completely overcast or rainy weather outside of a direct storm threat.
2. Hurricane Risk: The primary concern during this season is the potential for hurricanes or tropical storms, which can disrupt travel and cause significant damage. It’s a real factor to consider when booking.
3. Pros of the “Green Season”: This period is also called the “green season” for a reason—the island is lush and vibrantly green. It’s also less crowded, and hotel rates can be significantly lower than during the peak winter season.

In summary: For the lowest chance of rain, visit between December and April. If you don’t mind a higher (but not guaranteed) chance of brief showers and are aware of the hurricane risk, the August to November period offers value and lush scenery. Always check hurricane forecasts when planning a trip during late summer or fall.
