During the dry season, from November to April, precipitation is not abundant, although some rainfall may occur, caused by cold fronts coming from the United States. These cold fronts can lower the temperature by a few degrees, but not at the level of the north side of Cuba. However, from December to mid-March, some days can be a bit cool, with highs around 20/22 °C (68/72 °F) and lows around 15 °C (59 °F).
On the contrary, from May to October, it's hot and humid, though fortunately, sea breezes blow.
In the period from June to November, Cayo Largo, like the rest of the Caribbean, can be affected by tropical storms and hurricanes, which, however, are more likely between August and October.
The amount of sunshine in Cayo Largo is good all year round, however, it's slightly lower from November to February because of the aforementioned northern disturbances. Here are the average sunshine hours per day.
