The month of November is, technically, the last month of hurricane season - which closes on November 30th.
Last year, much to the confusion of all involved, we still had "tropical activity" in early December - and nobody understood why.
Normally, as has been said before (and indeed, by yourself), November is gorgeous.
The tourists will have started arriving, the queues in the restaurants will be getting bigger, the hotels will be getting more expensive....the weather SHOULD be just fine. Don't quote me on it.
