Thanks to its location to the north of Portugal, roughly midway up the west coast of the Iberian Peninsula, Porto weather provides a comfortable climate for its visitors. Winters are relatively mild in comparison to the UK and other cities further to the east of Europe, while summers are deliciously warm without being too hot.
Weather in Porto is best in July and August if high temperatures are at the top of your agenda. Porto weather during these summer months is at its warmest, with average daily highs in the upper twenties. This is also the time when the weather in Porto is at its driest, so you are unlikely to have your sightseeing plans hampered by heavy rainfall.
Unlike some Mediterranean destinations which can be hot and muggy overnight, Porto benefits from a position right at the mouth of the Atlantic Ocean, with cool breezes sweeping in from the west and very low humidity. This means that while it is still perfectly pleasant to enjoy an evening eating al fresco under the stars, you are likely to get plenty of rest and relaxation with a comfortable night’s sleep.
Rainfall during the spring and autumn months is higher than in the summer all over Portugal, and the weather in Porto is no exception. The rains begin to increase in mid to late September and rainfall is generally at its highest in December and January. However, unlike some other countries (Britain included!) the rains are certainly not accompanied by uncomfortably cold temperatures, with average daily highs rarely falling beneath 12 or 13 degrees Celsius and often up in the high teens and low twenties.
One of the benefits of Porto’s more temperate climate is the wonderful blooms that are in evidence from late February onwards, making this city in northern Portugal a favourite with travellers just about all year round.
