September Weather in Portugal

Youโ€™ll be happy to know that Portugal is one of Europeโ€™s warmest countries! With a Mediterranean climate, you can expect humid, cool winters and dry, hot summers – with variability by region and season.

September is the best month to visit Portugal because the temperatures drop a bit, while retaining the remnants of summer weather.

Note that ocean water temperatures are very cold in Portugal year-round (61 ยฐF)โ€ฆ But they warm up to as high as 67.8 ยฐF in September.

What to Pack for September Weather

Wondering what to pack for your September city break in Lisbon? Remaining summer heat (highs of 86 ยฐF) in early September mean youโ€™ll be set with shorts, tank tops, and dresses. In late September, that number drops to 76ยฐF; perfection! In the evenings, have pants and a jacket on hand, since temps can dip to 61 ยฐF.

Porto, another popular city break, has cooler September averages (highs of 75 ยฐF, lows of 58 ยฐF), due to its proximity to the Atlantic Ocean.

In general, itโ€™s a good idea to pack a jacket or sweater for all your travels. Portugal is no exception!

Fancy a trip to the Algarve? Make sure to bring your swimsuit! Resort towns such as Lagos see temperatures dip from the high 80s in the summer, to the mid-70s in September. Sweet relief!

As for rainfall, thereโ€™s a chance youโ€™ll encounter rain during the shoulder seasons, but itโ€™s low.

Fun fact: The mountainous regions of northern and central Portugal can receive rainfall measuring two meters or more during the winter months!

The weather in Portugal in September is mild. All over the country, people relish in relief from the summertime heat. The wonderfully warm autumn weather is perfect for enjoying outdoor adventures, from the beach to the mountains.

By September, nighttime temps have significantly cooled off, too. On the flip side, the sea temperatures are the warmest theyโ€™ve been all year! Hello, surfing? 

P.S. For experienced surfers, fall and winter are the most idyllic months for big swells – from Sagres to Nazarรฉ.

Fewer Tourists

In September, school holidays have come to a close, meaning college kids are back to their studies, and family vacations have come and gone. At last, some peace!

Of course, there will still be travelers (after all, this is the best time of year for those in-the-know), but the tourist age group increases. Older travelers make their way to resort towns in the Algarve, while the giant street parties in Lisbon disperse.

Indeed, it is a more relaxing affair. By late September, the resort towns and cities have quieted down even more.

Our Lady of Nazare Festival (Mid-Sept.)

Some refer to Nazarรฉ as the most picturesque town in all of Portugal – pay a visit to this beautiful fishing village during the Our Lady of Nazarรฉ Festival! Witness spectacular bullfights, concerts, and folk dancing. Though this festival celebrates an important story of the Virgin Mary, there is an emphasis on the procession of the fishermen of Nazarรฉ, who risk their lives in the treacherous sea. A powerful celebration, indeed!
