July Weather in Puerto Rico





The tables below give the normal July temperatures and rainfall for cities and popular vacation spots in Puerto Rico. There's also information here on hurricanes, plus this month's average humidity and ocean temperature.

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.
