Dear Tamara,
The temperature varies very little year-round. The summer months (July-September) often seem warmer because the Trade Winds die down during that period but it's rarely that a visitor notices anything in the least bit uncomfortable.
End of October ostensibly sees the end of hurricane season but that's not a "given" by any means. However, we've been gratefully spared again - so far - this year. The odd tropical wave coming through can bring heavy rains which usually pass over relatively quickly and there's NEVER a local weather forecast which says anything less than a 30% chance of rain.
If you go to the "weather" section on the top right of this forum you'll find more information.
Hope you enjoy your visit here!
