St. Helena - Weather

St. Helena Weather for Sailors

The climate is temperate, with moderate rainfall and high humidity. Average temperatures are 20-27°C, although can reach mid 30's in the summer months (between January and March). St. Helena is in range of the SE trade winds, so the wind is strong most days and this keeps temperatures down. Gales are frequent all year round but the island is not subject to hurricane/typhoon strength winds. The main rainy periods are in March and August, however, the weather can vary greatly around the island. Being so close to the equator, the day length does not tend to vary throughout the year and there are no notable seasons.
