LISBON Weather Forecast & Climate 2020

Summer Warmth

In July and August, temperatures in Lisbon average out at around 26-27°C, so although you’ll want to bring sunglasses, sunscreen and loose clothing, it’s not too hot for exploring and enjoying all that the city has to offer.

Be aware, however, that many local people vacate the city during August to head off on their own holidays, so this can leave it feeling rather fake and touristy at times, not to mention more expensive than at other times of the year.

Winter and Autumn Chills

If you’re visiting Lisbon in the winter, between November and March, take an umbrella. There’s never a huge amount of rain, but you’re quite likely to experience some rain. The winter months get around 3-4 inches of rain each, but it’s widespread, so in January, for instance, it can rain briefly on as many as 15 days of the month.

During the winter and autumn, take a cardigan or light jacket too, for the chillier nights. It’s not unknown for temperatures to fall below freezing overnight in Lisbon, but it is rare.

Spring Blossoms

Spring can be one of the nicest times to visit Lisbon. In April and May the flowers begin to bloom, and the temperature climbs nicely, but not overwhelmingly. Lisbon is not yet at the peak of its tourist season, so you’ll find fewer crowds and a more authentic experience.
