The Cayman Islands have a warm, humid tropical marine climate. It is characterized by a rainy season running from May to the end of October, and a dry season for the rest of the year. The average temperature ranges between 25 and 30°C year-round, though it can feel more oppressive during the rainy period, particularly from August to October when rainfall is heaviest. The archipelago is also prone to hurricanes between June and November.
