Annual Average Temperatures & Rainfall in Puerto Rico





The tables below give the annual average temperatures and rainfall for cities and popular vacation spots in Puerto Rico. There's also information here on the average humidity and ocean temperature at San Juan.

The measures of climate are averages of historical data collected at weather stations over several decades.

One site, Pico Del Este, is much cooler and rainier than others on the list. That's because it's a high mountain peak, at 3448 feet (1050 metres) elevation, in the El Yunque Caribbean National Forest.
