Best Time to Visit Algarve: A Local Insider’s Complete Weather Guide
Portugal Algarve Weather enjoys a classic Mediterranean rhythm that visitors find hard to resist. Long stretches of hot, cloud-free summer days give way to winters that stay mild, with only light, refreshing rainfall.

Here's why:
Portugal Algarve Weather offers one of the most reliable climates in Europe. Summers last from late May into early September with daytime highs commonly reaching the upper twenties Celsius, blue skies that hold from dawn to dusk, and virtually no rainfall. Even in January the Algarve often records sixteen degrees and at least five hours of sunshine, so outdoor plans rarely need to be cancelled. Short, gentle showers arrive between November and February, keeping the countryside green without settling in for long.
Spring is a favourite for many travellers. March signals the start of almond blossom and clear skies, while temperatures climb close to twenty degrees. April and May add two more hours of daylight, sea breezes that make the warmth feel pleasant, and minimal rain. This combination attracts leisure guests who want beach time, coastal walks, or an early round of golf before high-summer crowds arrive.
Corporate groups benefit most from the shoulder months. April through June and again September through October deliver bright sunshine, stable afternoons above twenty three degrees, and a calmer atmosphere at hotels and venues. Meeting terraces are comfortable rather than hot, evening dinners can be held outdoors without the bustle of July holidaymakers, and suppliers have greater flexibility on pricing and availability. For retreats and offsite gatherings that aim to balance focused work with memorable downtime, these two windows provide the Algarve’s best mix of privileged weather, long daylight hours, and manageable visitor numbers.
