We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The chance that a given day will be muggy in San Juan is increasing during April, rising from 88% to 97% over the course of the month.

For reference, on June 12, the muggiest day of the year, there are muggy conditions 100% of the time, while on March 9, the least muggy day of the year, there are muggy conditions 81% of the time.

Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).

Temperatures in San Juan are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year.

Temperature and Dew Point

There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in San Juan.

For each station, the records are corrected for the elevation difference between that station and San Juan according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

The estimated value at San Juan is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between San Juan and a given station.

The stations contributing to this reconstruction are:

Luis Muñoz Marín International Airport (TJSJ, 94%, 7 mi, east, -30 ft elevation change)
Mercedita Airport (TJPS, 6%, 44 mi, southwest, -10 ft elevation change)

TJSJ, 94%7 mi, -30 ftTJPS, 6%44 mi, -10 ft

To get a sense of how much these sources agree with each other, you can view a comparison of San Juan and the stations that contribute to our estimates of its temperature history and climate. Please note that each source’s contribution is adjusted for elevation and the relative change present in the MERRA-2 data.

Other Data

All data relating to the Sun’s position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA’s MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Things to know about Puerto Rico

The insular area of Puerto Rico in the Caribbean impresses with its beautiful and quiet bays, a lively capital city and a huge amount of nature and greenery. Here is a guide of what to explore on this stunning island.

Whether you arrive by air or sea, whenever you travel to Puerto Rico you first land in its lively capital San Juan. You should really spend at least one night there before you continue your travels towards the jungle or dream beach vacation. Real Caribbean flair awaits you in the Old Town of San Juan. The UNESCO world heritage site Castillo San Cristobal was built by Spanish colonies and is a must see. An outline of local culture and history can be explored in the Museo de San Juan and on Saturday mornings you can get a taste of all the local specialities during the farmers market (8am – 1pm, 150 Calle Norzagaray). Coffee lovers must try a coffee made from local Puerto Rican coffee beans at ‘Caficultura’ (401 Calle San Francisco). And try a Chichaito cocktail at Bar Los 3 Cuernos (403 Calle San Francisco).

Around 7 miles east of Puerto Rico you will find the small island of Vieques. You can get there easily by ferry boat from Fajardo or by plane from San Juan. The beautiful and untouched island impresses with stunning beaches and totally empty bays where you might spot a passing wild horse now and then.
The best accomodation on Puerto Rico is provided by the W Retreat and Spa. It’s directly on the beach, offers plenty of quiet spots for couples as well as stunning areas for families. A highlight is the infinity pool with underwater music. The rooms are beautiful and the restaurant offers unbelievably beautiful views across the sea. Every day you can participate in tours around the nearby national park which occupies around two thirds of the island.
The Blue Hole, near Villa Montones, is a water hole in the sea. It appears suddenly and offers views of the colourful underwater world- a real snorkeling hotspot!
On your way to the Blue Hole you will pass ‘The Breakfast Club at Ola Lola’s. Youngsters serve fantastic food and drinks any time of the day and it’s a great place to chill and hang out. Cash only!
A drive along the Ruta Panoramica, which goes across the island for 167 miles, is a fantastic way to see everything the island has to offer- from mountain regions to bamboo woods, a series of abandoned places and coffee plantages. All the way you have incredible views out over the sea.

Aguadilla is a great base for further excursions around the island. From here you can easily reach the surfer hotspot of Rincon. In Aguadilla itself is the former Ramey Air force base of the US Air Force and if interested you could visit its museum too.
The time when Puerto Rico was one of the main sugar producers in the world is gone but what remains are the Lost Places. The ruins of the sugar cane plants have something charming. Most interesting are the abandoned plants of Central Coloso and Playa Lucia as well as the Guajataca Tunnel, which used to connect the towns of Isabela and Quebradillas.
Isabella, or the ‘garden of the Northwest’ is the perfect base in order to explore the surrounding villages and beaches. The sea is rough and the waves are high. Children and those who can’t swim can splash around Swimming Holes, such as the Pozo Teodoro, where the water collects up to knee level and is warmed by the sun. From here you can also easily reach the surfers mecca of Rincon. You should stay there until sunset which surely is one of the most impressive in the Caribbean.

Approximately 2 hours by car from San Juan you reach El Yunque. Inhabiting 28,000 acres it is the only rainforest on US territory. Whilst walking along beautiful trails you can see over 240 species of animals and plants. A beautiful refreshment is offered by the waterfall of La Mina.
