Puerto Rico Water Temperatures

The scenic Caribbean island of Puerto Rico lies just to the east of the Dominican Republic, and west of the US Virgin Islands.  A terrific choice for holidays where sun, sea and sand are on the agenda, Puerto Rico is easy to reach from Europe and the US by air or sea.

The country lies on a main route to the Panama Canal (the Mona Passage), and over 1 million visitors each year arrive at Puerto Rico by cruise ship.  From the El Yunque rain forest to the white sand, tropical beaches, there is something to appeal to everyone in Puerto Rico.

Water temperatures off the coast of Puerto Rico vary little throughout the year, and the sea is perfect for surfing, swimming, diving, kayaking and sailing at almost any time.  Temperatures range from 79F or 26C in January to 82F or 28C in July, meaning that it is always as warm as a pleasant bath and ideal for a memorable holiday or break.

Best time to visit Puerto Rico

Like the sea, the temperature on land remains stable all year round thanks to the warm water of the tropical Atlantic.  In January, daytime temperatures typically fall between 72F or 22C to 83F or 28C, rising to an annual high of 78F or 26C to 89F or 32C through June, July, August, September and October.  It tends to be slightly warmer in the south than in the north, and the rainy season is April to November.  Take cool, summery clothing and a light waterproof jacket.

You should see this when you visiting Puerto Rico

Puerto Rico was discovered by Christopher Colombus in 1493, and is a US territory today.  Discover the glorious beach and terrific wave conditions at Rincon beach, the ‘surf capital of the Caribbean’.  The lighthouse dominates the skyline and every road leads to somewhere special, including the famous Rincon 413, the ‘road to happiness’.  Visit El Yunque rainforest which can be accessed by walking up the mountain directly from the road.

Swim in the crystal clear pools at the foot of the La Mina waterfalls and try to spot a rare Puerto Rican parrot.  Bear in mind that El Yunque is a rain forest so rain is likely, and do take a waterproof jacket.  Go horseback riding on Aguadilla beach, or enjoy a round of golf at the Trump International Golf Club near San Juan; an 18 hole championship course that was designed by Tom Kite.  There is always something exciting to do, and at the end of the day the sunsets are spectacular, particularly from the beach.
