(Lisbon, Portugal)



Picture of statue at the top of the Arco da Rua AugustaLisbon's appealing climate is amongst the warmest of any European capital city. With extremely mild winters, plenty of hot summer weather and around 3,300 hours of sunshine, it is no wonder that Lisbon has become Portugal's number one tourist destination.

The springtime temperatures are especially favourable and regularly hover around 25°C / 77°F, while in the very heart of the summer, climate extremes and strong sunshine cause peaks of more than 30°C / 86°F.

Seasonal Climate Variations / When to Go

August is predictably the hottest month in Lisbon and daytime temperatures regularly average 28°C / 82°F, staying only slightly short of 20°C / 68°F by night. As a result of these mild, balmy evenings, many of the restaurants regularly spill out onto the pavements and main squares, remaining open late, together with the bars and clubs. However, Lisbon's proximity to the sea and resultant breezes can make the temperatures feel a little cooler at times.

Many of Lisbon's biggest and most popular festivals take advantage of the fine summer climate. These include the Cascais International Sailing Week in July and also the BaixAnima Street Festival, which takes place each year between July and September and includes plenty of street parties and colourful parades.

December and January are usually the coldest weather in Lisbon, although daytime temperatures still average 14°C / 57°F or more. However, despite this extremely mild climate and regular sunshine, snowfalls are not unheard of, although are in actuality extremely scarce. Occasional brief flurries of sleet or snow can fall in January, arriving from the Arctic and rarely settling.
