Climate & Weather in San Juan

Good to Know

• December–April is peak tourist season: expect higher prices and larger crowds, especially in Old San Juan.
• Even during hurricane season (June–November), direct major hurricane hits are statistically rare, and morning weather is often clear with showers developing mainly in the afternoon.
• February and March offer the ideal balance: dry weather, lower humidity, and fewer crowds than December–January.
• May–June shoulder season provides good weather with noticeably fewer tourists and moderately lower prices than peak season.
• Rain during the wet season typically comes as short, heavy afternoon thunderstorms that rarely last all day—outdoor activities remain viable with proper planning.
• No snowfall occurs; lightweight, breathable clothing is appropriate year-round.
• August is the single wettest month and also part of peak hurricane season—balance the higher rainfall risk against potential hotel discounts during this low-tourism period.
