Puerto Rico Weather in September

Averages By Month

September is the last of the four hottest months in Puerto Rico . It has highs of 89°F. The sea is also beautifully warm with its water temperature of 84°F and the sun shines for almost 8 hours each day. Plan to spend the mornings on the beautiful beaches as afternoon rain showers are typical with 17 rainy days on average for the month. Whether rain or sun, temperatures rarely drop below lows of 78°F. September is also the peak hurricane season so plan some inside activities too and you should be able to find some great flight and hotel deals.

A great way to entertain yourself whilst the rain showers are passing through might be to take a Salsa Class. If you aren’t into dancing, you could simply check out some of the fantastic museums. There are some street fests and the Oktoberfest in the Casa Bavaria already starts at the end of this month too!
