The climate in the Algarve can be divided into four seasons. Summer is particularly inviting from June to September with maximum temperatures of around 86° F and fantastic water temperatures of around 68° F for sunbathing and swimming. Spring and fall, on the other hand, are perfect for exploring the beautiful region on extensive hikes, a city trip or other rewarding outdoor activities. Even the winter months of December to February promise a fantastic relaxing vacation in the Algarve with temperatures of around 59° F. However, you should take a rain jacket with you in the Algarve at this time of year as a precaution.

The high season in the Algarve runs from June to September and coincides with the summer vacations. This attracts not only Portuguese but also numerous international visitors to the picturesque coastal region, making it very busy. At the same time, temperatures of around 86° F, up to 12 hours of sunshine, virtually no rain and, last but not least, pleasant water temperatures make the Algarve the perfect destination for a relaxing summer and beach vacation during these months.

Spring and fall are considered the shoulder seasons in the Algarve and guarantee optimal climatic conditions for an unforgettable vacation. From March to May and in the months of September and October, you can enjoy pleasant temperatures of around 68° F, plenty of sunshine and only the occasional rain shower. This is therefore the best time to go hiking in the Algarve or to spend a unique relaxing vacation on Portugal's fantastic coast.

From December to the end of February, the Algarve becomes noticeably quieter. Temperatures here also drop to a maximum of 61° F, there is more rainfall and the sun only warms the coastal region for around six hours a day. Nevertheless, the Algarve is still worth a relaxing vacation in winter. What's more, you can now enjoy the region's beautiful nature at particularly attractive prices.

The Algarve not only boasts a breathtaking coastal region, but also offers fantastic golf courses. However, if you want to play golf in the Algarve, you should plan a trip in spring or fall, when temperatures hover between 61 and 68° F and there is only occasional rainfall.

The best time to go hiking in the Algarve is in spring or fall. Between March and May, as well as from September to the end of October, you can expect plenty of sunshine and pleasant temperatures between 61 and 77° F. These are ideal conditions for exploring the unique natural surroundings on long hikes or challenging treks.

Midsummer from June to September is particularly suitable for a beach vacation. This is also the best time to travel if you want to surf in the Algarve. Water temperatures above 68° F, plenty of sunshine, glorious temperatures of up to 86° F and, last but not least, optimal wind conditions create the perfect atmosphere for surfing or wave riding.

Would you like to explore the dream region of the Algarve while diving or snorkeling? Then a trip between June and September is particularly recommended, when the water temperatures slowly climb above 68° F and the underwater visibility gives you a fantastic insight into Portugal's underwater world. What's more, you can not only enjoy the region while swimming or relaxing on the beach, but also explore the surrounding area.

The proximity to the Atlantic Ocean and the Mediterranean climate in the Algarve ensure pleasant temperatures, long hours of sunshine and little rain all year round. A mild climate makes the Algarve a fantastic travel destination all year round. Temperatures climb up to 68° F from as early as May. And even in midsummer there is no excessive heat. However, spring and fall are the best times to travel to the Algarve to enjoy the magical region on hikes or while surfing. On the other hand, those planning a pure beach vacation in the Algarve should take advantage of the peak travel season from July to September, when the water temperatures rise above 68° F.
