Insider timing tips

•The dry season (December to April) offers the most predictable, pleasant weather, but coincides with peak tourist demand and prices.
•Shoulder seasons (April-May, November) provide a good balance of decent weather and fewer crowds, though humidity begins to rise in May.
•Hurricane season runs from June 1st to November 30th, with the highest risk typically in August and September. Travel insurance is highly recommended during these months.
•While San Juan itself doesn't have a specific 'Carnival' date, February often sees celebrations across the island that can influence travel if you plan to venture out.
•Local holidays and festivals, especially around Christmas and Three Kings' Day (January 6th), can lead to closures of smaller businesses and increased local travel.
