Weather and Climate

Cayo Largo has a subtropical climate that is divided into two seasons: the WET SEASON from May to October, and the DRY SEASON from November to April. The dry season is the busiest tourist season.

Cuba is located at the southwestern periphery of the North Atlantic high atmospheric pressure zone. Its climate is influenced by the northeast trade winds during the winter and east-northeast trade winds during the summer. Cayo Largo is a warm place to visit any time of year. Average day-time temperature usually ranges from 28 to 32 C (82 to 90 F), and night-time temperatures from 18 to 24 C (64 to 75 F). See the charts of monthly averages below.

Since Cayo Largo is located off the south coast of Cuba (in the Caribbean Sea), this is a place where you can expect slightly higher temperatures and a drier climate than most other Cuban tourist areas (most of them being on the north coast of Cuba). But evenings and nights might still be "cool" between late-December and early-March, we suggest packing a sweater or light jacket, just in case.

The hottest months are from June to September, but the trade winds and sea breeze help to keep things tolerable when the heat and humidity rise. During the wet season expect more mosquitoes and sand flies. It is suggested to always bring a good mosquito repellent (preferably with a high content of DEET), no matter when you travel.

September-October is the peak of the hurricane season, and consequently the cheapest time to travel. A major hurricane does not come every year, but when it does it can cause severe damages, floods, and ordered evacuations; such as the infamous Hurricane Michelle (category 4) that hit Cayo Largo on November 4th, 2001.

The most enjoyable periods (weather-wise) are usually the transitional months between the two seasons, which are: March and April, and November to mid-December. These months are usually sunny and warm (both day and night), but without the hot and sticky discomfort of the summer months (May to October), and without the risk of “cooler” evenings (like in January and February).

NOTE: You should never take too seriously the weather forecast for tropical destinations, such as the Caribbean, because the climate is unstable therefore very hard to predict, especially during the wet season (May to October) when rain is forecasted almost daily. It may indeed rain a little each day, but most often as a short tropical downpour (usually in late afternoon or at night), it rarely rains for several hours straight.
