Averages for San Juan in January

Puerto Rico, known as ‘Rich Port’ in Spanish, lies in the northeastern Caribbean to the east of the Dominican Republic, and to the west of the Virgin Islands. This mountainous area enjoys a year round tropical climate with little to no variation between the seasons.

January is renowned for being one of the coldest months in Puerto Rico, but a typical Puerto Rican winter doesn’t tend to see temperatures dip below 19 degrees Celsius. In fact, daily highs often reach 28 degrees. Around 4.5 inches of rain is expected to fall over 20 days so it may be wise to pack a light jacket along with the sun cream.

Party lovers will love the atmosphere of Puerto Rico in January. The San Sebastian Festival, often likened to Mardi Gras or the Notting Hill Carnival, occurs annually in San Juan and draws in thousands of tourists looking to drink, dance and have a good time. The January rain doesn’t dampen spirits and the celebrations continue no matter what the weather.

It’s advisable to stay in San Juan during the festival as travelling into the area amidst the crowds can be a nightmare. The Dreams Hotel is located at a prime location in the city and, with rooms from just £31 per night, is ideal for those wanting to stay in party central without paying the high prices.

Adrenaline junkies should shoot over to Caguana, just an hours drive west of San Juan, and book in with Batey Zipline Adventure. Sliding down a rope 220 feet above the ground offers the ultimate thrill but it’s not for the fainthearted!
