Weather in Lisbon

Lisbon weather boasts a subtropical Mediterranean climate, with mild winters and summers that range from pleasantly warm to deliciously hot. The summer season is typically dry, with rains ceasing more or less completely between May and October.

Weather in Lisbon is at its hottest in July and August, when temperatures can reach as high as the mid-thirties, and sometimes even a little more. This is offset by lovely temperate evenings, which are warm enough to enjoy the outdoor lifestyle and yet cool enough to ensure a perfectly good night’s sleep.

This is also the perfect time to enjoy a short night-time stroll around the liveliest parts of town.

In fact, Lisbon, Portugal, has the mildest night-time temperatures in Europe, averaging a delightful 18.6 degrees Celsius during the summer and a perfectly respectable 8.3 degrees Celsius during the coldest month of January.

Even during the coldest month of January, weather in Lisbon is significantly warmer than in the UK, and beats many other locations in Portugal. Daytime temperatures typically range between 11 and 19 degrees Celsius and even the sea temperature only falls to 15 degrees from its 20-degree summer high.

Spring and autumn in Lisbon can be changeable, but are equally capable of delivering exceptionally warm temperatures, often exceeding 25 degrees Celsius. Daytime averages during those months are 18.9 degrees, falling to an average 12 degrees at night.

December to February sees the highest rainfall, however there are still many sunny days and there is plenty to do under cover in Lisbon to make Portugal’s capital a very popular year-round holiday destination. The lovely cafés, museums and traditional shops will make for wonderful stops during the coldest and rainiest months of Lisbon, giving you the chance to know a little bit more about local details.

Don’t forget to pack light clothes, sun-screen, sunglasses, hats, and other sun-protection garments to help you enjoy the most of your days during summer, although you’ll probably need a jacket at night, just in case; during winter months, an umbrella and warm coat is essential.
