Best Times to Visit Lisbon
The best time to visit Lisbon is either from March to May or September to October, because the weather is still warm, hotel rates are cheaper and there are fewer crowds than in summer. In those seasons you might also be able to squeeze in a few beach days. The summer sees hot temperatures and crowded shores. Winters in Lisbon are warm for Europe, in the 50s on average.
Hotel rates and crowd density drops in these shoulder months, with the exception of Carnaval in March. There is a slightly higher chance of rain, but the pleasant temperatures hover in the 60s and 70s.
As with most of Europe, summer is Lisbon's high season. Hotel rates climb, the best restaurants are booked and the city's monuments have tourists wall-to-wall. But with temperatures soaring above 80 degrees Fahrenheit, you can add beach hopping to your itinerary.
Similar to the spring, fall is less expensive and less crowded. Temperatures begin to drop into the low 60s and high 50s, so be sure to pack your windbreaker.
Daytime highs rarely fall short of the mid-50s in winter, which is very pleasant by European winter standards. But much of Lisbon's lure is in its walkability, so beware of the potential for rainy days that can put a damper in plans to stroll. Keep in mind that the months between November and February are typically Lisbon's wettest.
