Insider timing tips
- •The 'dry season' (December-April) offers the most reliably sunny and least humid weather, but coincides with peak tourist season and highest prices.
- •The transition months of April and November provide a good balance of pleasant weather and fewer crowds/lower prices than the absolute peak.
- •San Juan experiences a distinct wet season from May to November, characterized by increased humidity and frequent, though usually brief, afternoon thunderstorms. This period also carries hurricane risk.
- •While August and September are cheapest, they are also the most vulnerable to tropical storms and hurricanes, which can cause significant travel disruptions and closures.
- •Many smaller, local businesses, especially outside tourist zones, may observe reduced hours or close entirely during major local holidays like Thanksgiving and Christmas.
