The western Caribbean is notorious for being the location where some of the world’s most intense hurricanes are born.

A combination of moisture in the atmosphere, warm ocean temperature and winds make this area the ideal nursery grounds for hurricanes.
Statistically the overall peak time for hurricanes is midway through the month of September, but that is not the case for us here in the Cayman Islands. The Caribbean hurricane season reaches its peak during October (Source: the World Weather Travelers Guide). The surface ocean temperature during October is approximately 1°C warmer in the south-western parts of the Caribbean than any other month of the year and during this time, rainfall increases providing the necessary ingredients for a hurricane to form.
