September, October bring the lowest rates of the year, with the trade-offs the table shows: this is when rain and storm risk peak, so book flexible rates and add trip insurance.

If you're going in peak season anyway

January, February, March, December are the premium months: the best odds of perfect weather, and the highest prices and crowds. Book 6 to 9 months out; this is when the good rooms genuinely sell through.
