There is never a bad time to head to the Caribbean, but travelers may want to keep an eye on the Puerto Rico climate before booking their trip to San Juan. The U.S. protectorate boasts a robust tropical weather system that ensures year-round warm weather, but higher than average rainfall and a consistently strong level of humidity.

San Juan, Puerto Rico’s capital and most populous city, it located on the country’s northeastern coast and is one of the country’s most important seaports. It’s this same relationship with the sea that thrusts the city into a tropical monsoon climate.

The city averages a temperature of 79.9 degrees, though breaks into the 90s during the summer - and with more than 51 inches of rain each year, travelers can expect a drizzle regardless of when they visit.

For these reasons, the best time to visit San Juan is probably in late February or March as temperatures begin to dip (the lowest on record is only 60 degrees) and the skies begin to clear, with rainfall dropping to just 74 millimeters for the month.

Travelers will also want to prepare for the intense humidity of the region, with the average rating hovering around 80 percent year round.
