What’s is Puerto Rico’s Average Weather?

Overall, the temperatures are steady throughout the entire island.  Puerto Rico’s climate, is part of the tropical climatic zone.  In general, residents and visitors enjoy warm temperatures all year round averaging 80 °F (27 °C) in lower elevations, and 70 °F (21 °C) in the lush central mountains of the main island of Puerto Rico.  Most of the year, the weather is simply perfect.  Because Puerto Rico is a tropical island, quick changes may occur from one week to the next.  There are some differences in weather conditions among some regions of the main island and the offshore islands of Vieques & Culebra.  Before you travel, be sure to check for weather alerts.

When is Puerto Rico’s Rain Season?

Rain season in Puerto Rico is from April to November, but don’t let that deter you from coming to the island during this season.  Hotel rates tend to be lower at this time of year, you’ll find amazing deals at top beachfront hotels and resorts that may not be in your budget during high season in the winter months.

Rain showers are typically scattered in the afternoons and don’t last very long.  The variations in temperature and rainfall are caused by the mountains in the center of the island.  Most likely, rain in Puerto Rico won’t ruin your whole vacation day.  For residents, beach time is summer time, during “rain season”.

Beating the rain

If you vacation in Puerto Rico during rain season, our best advise is to get up as early as you can to enjoy the beach, rain typically starts early afternoon.  What’s great about Puerto Rico is that it rarely rains all over the island at the same time, if may be raining in one region and in a half hour drive, you will arrive at another destination with bright blue skies, you can download the FREE World Radar App, we use it all the time during rain season to see where to go on a rainy day.  The south west of the island gets less rain during rain season.

When is Hurricane Season in Puerto Rico?

The official hurricane season in Puerto Rico is from June 1 to November 30, tropical storms typically hit the island during this time.  June to November is clearly a long season with risks of tropical storms and hurricanes, but island life goes on as normal.  Hotels are open, and tourist activities are just as fun.  Summer is actually high season for residents, families travel around the island, to enjoy our beautiful coastline.  Some of the best vacation deals are during this time of the year with hotels and airlines trying to fill up rooms and seats during this low travel season.

Historically, unlike Florida, Puerto Rico only gets hit by major storms and hurricanes years apart.  The majority of storms and hurricanes have taken place in the month of September.  The last hurricane in Puerto Rico was Hurricane George, the first major hurricane to hit the island in over 60 years, a Category 3 in September of 1998.  Two major hurricanes prior to George were four years apart: San Felipe II, one of the most intense hurricanes in Puerto Rico’s history on September 13, 1928; San Ciprián occurred on September 26-27 of 1932.

Tips when traveling in hurricane season:

  • Purchase travel insurance just in case.
  • Check the forecast closely a week before traveling in hurricane season.
  • If you want to play it safest, head to the west coast of Puerto Rico.  Tropical storms and hurricanes typically come in from the east, the west coast sees less rain and damage when compared to the rest of the island.

Best Snorkeling Weather Conditions in Puerto Rico

If you love snorkeling, water is clearest and calmer during the months of June, July & August.  Steps Beach in Rincon, one of the best surfing beaches, becomes one of the best snorkeling beaches during summer months.  Vieques and Culebra have clear waters all year round, but in the summer months, they’re incredibly clear, warm, and calm with virtually no waves (during normal weather).

Hottest Months in Puerto Rico

The hottest months are July and August, but they’re also some of the best months to enjoy the beaches of Puerto Rico.  Generally, Puerto Rico is breezy, and not very humid, even on a super hot day, breezes makes the heat pleasantly enjoyable.  Of course, the best way to beat the heat, is by jumping into our beautiful waters.  There’s about a 6 °F (3.3 °C) temperature change between winters and summer.

Weather Differences Across Regions of Puerto Rico

puerto-rico-weather-guide

When you do a search on Google for “Puerto Rico Weather”, Google shows you the weather in the capital city of San Juan.  San Juan is located on the north east coast of Puerto Rico which typically gets a little more rain than the southwest coast of Puerto Rico.

East Coast of Puerto Rico:  When the weather is “normal”, the east coast is a wonderful place to be.  Compared to the rest of the island, it feels more breezy like the north coast.  If you were unlucky to be here during a tropical storm, you’ll feel it more on the eastern coast of the island, since storms typically come in from the east. Overall, the east offers beautiful tropical weather all year round under normal conditions.

South west region: Temperatures are warmer in the south west region of Puerto Rico with less rain.  On the south west, you’ll find the Guanica Biosphere Reserve (commonly known as the Guanica Dry Forest), which only gets about 29 inches of precipitation per year.  The town of Cabo Rojo and Guanica are known for great weather all year round, dryer flora and less rain than most places around the island.  If you’re planning on traveling during hurricane season and want to play it safe, head to the west coast of Puerto Rico.  Tropical storms and hurricanes typically come in from the east, the west coast sees less rain and damage when compared to the rest of the island.  Again, the difference is not big enough to keep you from staying at the destination that appeals to you most, it only makes a difference during bad weather or a heavy rain season.

The offshore islands of Vieques & Culebra:  Culebra has a dryer climate with excellent weather.  Vieques is more lush and gets more rain than Culebra.  Like the main island of Puerto Rico, rain is typically sporadic and it doesn’t last all day.  Best thing to do is to enjoy the beach in the morning, most showers occur in the afternoon.
