The best time to go to Portel is during the spring (April to June) and fall (September to October) months.
These periods offer pleasant weather, with comfortable temperatures ideal for exploring the Alentejo region. You'll find sunny days superb for outdoor activities without the intense heat of summer or the cooler, wetter conditions of winter.
For travelers who enjoy outdoor activities like hiking or vineyard tours, spring and fall are particularly good. The countryside is lush in spring, and the fall brings harvest season to the vineyards, offering great experiences. The evenings are mild, allowing for comfortable dining outdoors.
If you prefer warmer weather for poolside relaxation or lake activities at the Alqueva Dam, July and August are suitable, though temperatures can be quite high.
