When should you visit San Juan?
San Juan is warm all year, so the choice comes down to storms, crowds and price. Mid-December to April is the dry, busy high season, with cruise ships in port most days. June to November is hurricane season, with the highest risk from August to October. Here is how all twelve months compare for weather, crowds, prices and events.

My recommendation
March–April
March and April are still in the dry season, with warm seas and sunny days, but the winter rush is fading. April usually brings lower rates and fewer people than February.
