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.

Weather Differences Across Regions of Puerto Rico
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.
