The best time to visit Puerto Rico depends on your island agenda. The “tourist” season is fall/winter (end of October through April), when waves on the west coast beckon to surfers and the tropical rain forests come to life. The beaches will be more crowded, but all the shops, restaurants, bars, and hotels are in full swing. Everything the island has to offer is at your fingertips. Summer is also a great time if you would like to just relax without all the nightlife and day trips. If you want the beach to yourself, plus a few vacationing Puerto Ricans, then head down between May and August for seclusion, but be aware these are also the hottest times of the year.
