The weather in Porto

In Porto the average temperature is very similar to the climate of other coastal regions of Portugal. Like Lisbon, the Atlantic winds make the summer in Porto benevolent, as far as heat is concerned. Contrary to what can happen in the interior of the country, with respect to the temperature, the seashore and the Douro River influence positively the climate in the city of Porto.

From autumn to spring it is usually – although it doesn't seem to be – a cold and rainy place. In fact, sometimes it can have quite a London feel (saving the differences). But, this is just a saying, because nothing can be as rainy and grey as the English city.

From April to September temperatures start to rise and rains cease to give way to perfectly clear and cloudless skies, splendid sunshine and nights refreshed by the Atlantic Ocean that bathes the coasts of Portugal.
