Climate Saint Barths
© Copyright
Saint Barthelemy has a consistant climate all year through. The island indeed experiences an almost constant temperature of 28/30 °C , both in and out of the sea. Unlike Guadeloupe and Martinique, it is hotter in the summer than in the winter, a season which is slightly more humid. But this humidity, which is bearable, is tempered by trade winds which blow from December to April. Rainfall takes the form of brief showers in September and October, the month when hurricanes are possible.
Therefore, contrary to the generally accepted idea that is unlikely to change any time soon (undoubtedly because it is associated to its large and remote neighbours Guadeloupe and Martinique), Saint Barts is an ideal holiday island for ten months out of the twelve and particularly from May to August.
