The climate and weather in Portugal is usually excellent, generally being neither too hot nor too cold. Portugal has a diverse climate from north to south and the weather varies considerably from one region to another, but in general Portugal offers warm and sunny summers, mild winters, and autumn and spring are normally warm however with some wind and rainfall.
The winter in Portugal generally starts in late November and lasts till February. March, April and October are normally very mild and the summer period is a nice long period from May to September.
The climate in the Oporto area and further up north is softened by the currents from the Gulf. The summers are sunny and pleasantly warm without becoming sweltering hot. In the regions of Oporto and Beiras, and in particular further inland towards Spain, the winters are colder than in the rest of Portugal, however, the temperature is still mild compared to the rest of Europe. It is possible to experience some snowfall in Portugal, however, it is rare and mostly occurs in the Serra da Estrela Mountains in central Portugal where the highest point in mainland Portugal is to be found.
The central regions of Portugal including Lisbon and The Silver Coast have a combination of elements from the Mediterranean and Atlantic climate which means mild winters and hot and dry summers. Especially the inner regions of central Portugal can get very hot during the summer with temperatures over 30 degrees, whereas a fresh breeze from the Atlantic cools down the coastal areas.
The southern regions of Portugal and the Algarve have a very dry and stable climate, and are influenced by both the Atlantic and the Mediterranean. The summers are very hot, however fortunately, and especially in the Algarve, the constant sea breeze helps to keep temperatures at pleasant levels. The southern part of Portugal is probably one of the sunniest places in Europe, even in the winter time, making it a very popular holiday destination.
