Unlike most countries, Puerto Rico is warm and balmy year-round. Temperatures rarely stray from the 24-29°C region, making it one of the most stable climates in the world.
Dry season usually runs from November to April, while June to September is wet season – hurricanes can also occur during this time, but you’ll have plenty of warning should there be any threat.
Generally, the south of the mainland enjoys warmer, drier weather than that of the north, while temperatures in the mountainous interior are a few degrees cooler.
