Puerto Rico's weather is moderate and tropical year-round, with an average temperature of about 82°F (26°C). There are no big seasonal changes, although winter sees cooling (not cold) breezes from the north, and temperatures in higher elevations drop by as much as 20 degrees. The rainier summer months are hurricane season in the Caribbean, which runs July through November. (Historically, August and September present the greatest risk for hurricanes.) The southwest is relatively dry year-round, while the region around El Yunque can be deluged at any time of year, feeding the lush rain forest.
