Weather in the Cayman Islands

caribbean beaches and holidays in the cayman islandsThe weather in the Cayman Islands is quite similar to the weather throughout the Caribbean. The islands – Grand Cayman, Cayman Brac and Little Cayman – are located in the western Caribbean. The Cayman Islands are northwest of Jamaica, east of Mexico, just south of Cuba and roughly 640km (400 miles) south of Miami. The three Cayman Islands are coral islands and although Grand Cayman is roughly 130km (80 miles) west of Cayman Brac and Little Cayman, all the Cayman Islands experience similar weather conditions and climate patterns. The climate of the Cayman Islands is a tropical marine climate. The dry season lasts from November to April, while summer is the wet season and lasts from May to October. Hurricane season occurs from July through to November.

Average temperatures in summer in the Cayman Islands range from 24 to 32 degrees Celsius (75 to 90 degrees Fahrenheit). Winter temperatures in the Cayman Islands are only slightly lower than summertime temperatures. The average temperatures in winter in the Cayman Islands are 22 to 30 degrees Celsius (72 to 86 degrees Fahrenheit). Humidity levels tend to be constant throughout the year, with the highest humidity levels experienced during the hurricane season months of August, September, October and November. Humidity levels tend to drop in the evenings as the trade winds have a cooling influence on the island’s tropical weather.

The wet season in the Cayman Islands runs from the end of May to October and sometimes into the beginning of November. The wettest months are June, August, September and October – they generally coincide with the Atlantic hurricane season. Rainfall during the wet season is short and sweet – the quick downpours are refreshing and generally don’t disrupt holiday activities. Although the Cayman Islands have over 300 days of sunshine per year, they also lie in the direct path of most of the major storm systems and hurricanes passing through the Caribbean. Therefore, the tropical weather in the Cayman Islands is best enjoyed outside of hurricane season.
