Here’s what you need to know about the weather in mainland Portugal and the islands of the Azores and Madeira.

Climate and Weather Conditions in Portugal

Portugal is known for having lots of warm sunshine throughout the year and a mellow winter.

Portugal is in southwest of Europe, a place commonly referred to as the Iberian Peninsula. It is a country with sublime climatic conditions like Spanish coastal towns off the Atlantic Ocean.

The weather in Portugal is characterised by very hot summer months, warm spring and autumn months and wet winter months. This is due to the Mediterranean climate enjoyed in Portugal which makes it one of the warmest European countries and a fantastic destination for anyone looking to enjoy a mild winter.

In the summer, there are many dry days with lots of sunshine of around 10 to 12 hours daily. The temperature also becomes increasingly hot and sometimes reaches an unbearable level in the month of August (the hottest month).

In autumn, the sunshine begins to reduce and the heat becomes less extreme and you can expect some rain towards the end of the autumn season.

In the winter the temperatures drop as low as 8°C (46°F) and the sunshine is only around between four and six hours per day. Also, there is a lot of rain in the winter months.
