Insider timing tips

•The summer months (July-August) are the hottest and most humid, coinciding with peak tourist season and highest prices.
•The shoulder seasons (April-May and September-October) offer the best balance of excellent weather, fewer crowds, and moderate prices.
•While rain is possible year-round, the winter months (November-March) tend to be slightly wetter, though rarely disruptive.
•Avoid booking around major US holidays (Christmas, Thanksgiving, Spring Break) if you want to avoid the highest prices and biggest crowds.
