The official Caribbean hurricane season starts in June, but the chances of actually being caught in a hurricane in June is very slim. Why? On average, only one tropical storm or hurricane is observed during the month of June every two years, according to the National Hurricane Center. For instance, there were only 33 hurricanes in June between 1851 and 2012, compared to 234 in August and 390 in September. Temperatures in June usually range from 78ºF to 87ºF (25.5ºC to 30.5ºC) while the average days with rain is only about 10, which makes June travel in the Caribbean is as enticing as any other month.
