Lisbon experiences mild winters and hot summers so it’s a great destination to visit year round. Portugal’s capital is also known as Europe’s sunniest capital with the highest amount of daytime sunlight on the continent and warm weather from May to September.
Season and Clothing
Summer: June to August
As Europe’s second-hottest capital after Athens, Lisbon’s summers are hot and dry especially in July and August when the mercury can hit around 40 degrees Celsius. Thankfully, summer nights are comfortably cool due to the ocean breezes. Summer is peak season in Portugal so expect crowds on the beaches and at main attractions. It’s also festival time with Festas de Lisboa street festival throughout June, Super Bock Super Rock and LGBT Sparkling Party.
Average temperatures: 17 – 28 degrees Celsius.
Appropriate clothing: T-shirts, shorts, dresses and sandals.
Don’t forget: Sunnies, sunscreen, swimmers and thongs.
Autumn: September to October
Summer’s warm weather can sometimes continue into the autumn months with average daytime temps in the mid-20s. Unpredictable rain and windy conditions are also common in autumn, punctuated by sunny days. The milder weather is also a good time to explore the churches, flea markets and historic buildings of Bairro Alto. These months also see MotelX – Lisbon’s International Horror Film Festival - as well as the Red Bull Air Race World Series.
Average temperatures: 15 – 26 degrees Celsius.
Appropriate clothing: T-shirts, shorts, jeans, pants and a hoodie.
