Especially in the north and central regions of Portugal, including Lisbon, the winter is rainy and chilly. The weather usually stays warm from May to September. The Algarve has extremely hot summers and a lot of sun even in the winter. Midsummer is also extremely hot in Alentejo. In the Azores the climate is mild year-round.
In Madeira, the climate is mild, more or less constant year-round with high temperatures in the summer. Actually, the island has two different climates. One on the north side, and a different one on the south side. The nearly 2000 m high mountains in the middle stop the rain coming from the north side. That gives a lot of rain in the mountains and on the north side. The south side also gets a lot of rain, but mostly as showers, and primarily in the winter. On Porto Santo (the other inhabited island of the archipelago of Madeira) the climate is very dry.|
