June Weather in Puerto Rico

The tables below give the normal June 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.

The temperature and rain measurements are averages based on weather data collected from 1991 to 2020 for the US National Centers for Environmental Information.

One site, Pico Del Este, is much cooler 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.
