Mediterranean climate predominates.
Portugal is predominantly characterized by a warm temperate, Mediterranean climate, with hot, dry summers and mild, potentially rainy winters, although the climate varies significantly across different regions. This climatic diversity is primarily influenced by the Atlantic Ocean and various geographical features. To gain a deeper understanding of the country's weather patterns throughout the year, you can explore the Comprehensive Guide to Every Season, which provides detailed insights into Portugal's weather intricacies.
Hot, dry summers.
In Portugal, hot and dry summers are characteristic of the southern regions, particularly in the Alentejo and the Algarve, where temperatures can exceed 100°F (38°C) and are mitigated by a constant sea breeze, especially in the Algarve. This beautiful coastal area benefits from the cooling effect of the ocean, providing some relief from the intense heat. The interior and southern parts of the country experience these extreme summer conditions, with the Alentejo region being notably hot and dry.

Influences from Atlantic Ocean.
The Atlantic Ocean significantly influences Portugal's climate, moderating summer temperatures and smoothing out winter's chill. This effect is particularly evident in the northern regions, where the ocean ensures summers remain temperate and winters are mild. In the southern areas, especially the Algarve, the ocean's influence results in hot, dry summers and mild winters.

Regional climate variations exist.
Portugal exhibits significant regional climate variations, with Northern Portugal characterized by a temperate maritime climate with cool, rainy winters and mild summers. Central Portugal enjoys a Mediterranean climate with hot, dry summers and cool, wet winters, while Southern Portugal, particularly the Alentejo and Algarve, experiences a hot-summer Mediterranean climate with hot, dry summers and mild, wet winters. The archipelagos of Madeira and the Azores have distinct subtropical and temperate maritime climates, respectively.
