Portugal Weather & Climate: Monthly Averages

The climate in Portugal is largely a blend of both Mediterranean and Atlantic climates. The differences in weather patterns across the country are quite significant, both from north to south and from coast to mountain.

Summer Weather

Summer is generally warm and sunny in Portugal. The Algarve and southern regions have a Mediterranean climate, meaning hot and dry conditions. Daytime temperatures are often around 28°C (82°F) in July and August, with the highest ever recorded at Elvas at 35°C (95°F). Days are pleasant, with up to 12 hours of sunshine per day. It does not rain at all during this season, and in Faro and the Algarve, rainfall is close to nil in July.

Autumn Weather

In autumn (September to November), temperatures become milder. However, Elvas can still reach 30°C (86°F) in September. Rainfall increases, especially in the northern regions, such as in Fajã Grande, where it reaches 109 mm (4.3 in) in September.

Winter Conditions

Winter, from December to February, is cooler, especially in the north and inland. Coastal regions tend to be milder; for example, Horta can reach 19°C (66°F) in January and February. Inland, at Miranda do Douro, lows of 1°C (34°F) are possible in January. The north, particularly Caminha, can expect up to 171 mm (6.7 in) of rain in December.

Spring in Portugal

Spring (March to May) is warm and dry. Temperatures start rising, reaching up to 26°C (79°F) in Elvas by May. In Soajo, it is 14°C (57°F) in March. Precipitation drops significantly, with May averaging around 28 mm (1.1 in) per month in Fuzeta.

Microclimates in Portugal

Portugal’s varied landscape results in microclimates. For example, the Azores remain mild and humid throughout the year due to their location in the Atlantic Ocean. These islands experience mist and rain showers even in the summer.

Best Time to Visit Portugal

When to visit Portugal depends on the activities you plan. Beach holidays are ideal during summer, from July to early September, though this is also the most crowded time. City trips and active holidays are best in spring or autumn when it is less crowded. These seasons offer beautiful weather for exploration and outdoor activities, with Lisbon averaging more than 200 hours of sunshine.
