Portugal is considered one of the warmest European countries, and the climate in Portimão is similar to that of the southern coastal regions of Spain and southwestern Australia. During the summer, you can enjoy 10-12 hours of sunshine at the resort.
Summer
In Portimão, summers are dry but not very hot. June is the optimal month for those who want to combine beach relaxation with sightseeing. The sun shines for almost 10 hours a day, but there is no scorching heat. In the height of summer, the air warms up to +27–28°C, rain is extremely rare, so it's a good idea to check the weather for the next 14 days before your trip to Portimão. Evenings on the resort, even in August, can be cool, so we recommend bringing a windbreaker or sweater.
Fall
In September, the tourist season is still in full swing in Portimão, with an average air temperature of +25–26°C. Many recommend traveling to Portimão with children, especially in September, as the ocean water, warmed by the August sun, is very warm at +22–23°C. In October, the swimming season comes to a close, but you can still enjoy sunbathing.
Winter
In winter, the weather in Portimão needs to be checked every 5 days due to variable cloudiness, cold winds, and frequent rains (up to 10 rainy days out of 30). The air temperature is quite comfortable at +15–17°C (it can get colder at night, down to +9–10°C, but there is no frost). February is the least touristy month, and the weather in Portimão during this time is unpredictable. Be sure to bring umbrellas and waterproof shoes.
Spring
Portimão starts to warm up in the second half of February, with the air temperature rising to +18–20°C. However, rains continue until April, so check the Portimão weather for the next week. May marks the arrival of consistently warm and sunny weather (+22–23°C), with very few rainy days (only 3–4 days a month) – perfect for the beach. However, the sea is still relatively cool at around +18°C.
When is the best time to visit Portimão?
The best time to visit Portimão is from May to October. For those planning to enjoy sun and sea baths, it's best to go during the summer months when the water temperature in the Atlantic Ocean warms up. However, don't expect the water to be very warm since the coastline is bathed by ocean waters. Tourists note that the air temperature in Portimão in February is +13–16°C, ideal for relaxation, walks, and cultural exploration. However, winter isn't suitable for active beach holidays but rather for contemplating the romance and beauty of nature.
