The islands of Portugal's Azores archipelago are a popular Portugal vacation destination for many reasons, not the least of which is the wonderful weather you'll find on a trip there. Let's take a look at the Azores weather and climate to help determine the best time to visit Portugal for your planned tours and travels.
The waters surrounding the islands of Azores are kept warm by the Gulf Stream. The best month for swimming is August, when the ocean is the warmest.
The islands' position at approximately the same latitude as Lisbon, Portugal gives them each a very temperate climate. In terms of the general climate, the islands are classified as "dry-summer subtropical."
Average high temperatures from July through October are in the mid-70s Fahrenheit, and they rarely dip below 50 degrees, even during the coldest months (December through March). With an overall average yearly high temperature of 67 degrees, and an average low temperature of about 58 degrees, you probably won't need your parka while on the Azores islands.
The Azores Islands are surrounded on all sides by the mighty Atlantic Ocean, so rainfall is fairly frequent there. No matter when you visit, you'd be wise to pack a rain jacket, just in case. The least rainy month on the islands has historically been July, when average monthly rainfall is just over an inch. June comes in second in terms of average sunny days, and typically receives just under two inches of precipitation. The wettest months are, in order, December, with 5.4 inches average rainfall; November, with just over 5 inches; October; January; and February.
Also, bear in mind that if it's raining on one side of the island you're on, it may be perfectly sunny on the other side. Consider escaping the drizzle by hopping in your rental car, and taking a short drive. Our tips on Driving in the Azores page is a great place to start.
There really isn't a bad time to take a trip to the Azores. Summer is perfect for spending your days on the beach, SCUBA diving, and whale watching. The spring is when all the azaleas are in full bloom, and the air is filled with a truly wonderful fragrance. The autumn and winter months are slightly cooler than the summer months, but not by much. True, you'll experience more rainy days, but you'll also get plenty of sun, and your visit may feel a bit more authentic for the lack of other visitors. Whenever you choose to visit, Azores is truly a paradise any time of the year.
