Bayamon Weather, When to Go and Climate Information

(Bayamon, Puerto Rico)

The coastal part of the San Juan metropolis is blessed with steady trade winds that cut down the intensity of the tropical sun and keep those pesky mosquitoes at bay. When you are hanging out in Old San Juan and around the Isla Verde area, you can enjoy the best weather conditions available in the region. Unfortunately, Bayamon is quite a way inland and doesn't benefit from a sea breeze. You can expect a 5°C difference between the two sides of the city throughout the year.

The summer climate runs from June to September and is both the hottest and wettest time of year. The city is pretty much hot and humid every day during this time, with only a brief respite when an afternoon thunderstorm rolls in and blows the air around. However, as soon as the storm dissipates, the humidity returns with a vengeance and turns the place into a greenhouse. From late September until the beginning of November, the rains are most frequent and heavy, so come prepared with good rain gear.

Seasonal Climate Variations / When to Go

Bayamon and the San Juan metropolitan area experience their best weather from December through May. This is when the tropical climate is especially pleasant, with temperatures hovering around the mid-20s (°C) during the day and cooling off a bit at night. Humidity levels are also lower during the winter, which makes the reliably sunny days a real joy.

The winter is when the San Juan region becomes most crowded with tourists. Expect overpriced room rates from December to April, and more people at the popular attractions than you would prefer. Before you plan your trip to Bayamon, check whether any of the patron saint festivals are happening in the city. These festive occasions are great to witness, but they also bring extra crowds. This boost in activity may or may not appeal to you. For the best deals on hotels, consider visiting in the summer if you don't mind a little extra heat.
