Best Time to Visit Lisbon (Month by Month)

By the Klemio team · Updated June 3, 2026

If you make us pick one stretch, it is late spring and early fall, May and June or September into October, when the city is warm and dry but not roasting and not yet jammed. Summer gets the headlines and the crowds, but July and August bring real heat to a city of steep hills you have to climb. Go in the shoulder and you get the same long days without sweating through your shirt on the way up to the castle.

Lisbon's weather is kind for most of the year. Summers are hot and bone dry, winters are mild and a bit wet, and spring and fall sit in a comfortable middle. The climate rarely ruins a trip. Crowds and heat are what actually shape when you should go.

One date dominates the calendar: June, when the city throws itself into the Festas dos Santos Populares for Santo Antonio. It is the best and busiest time to be here. If that is your trip, lean into it. If it is not, you will want to know it is coming.

Season by season

Spring

March to May
Weather
Mild and warming, mostly dry by May, with the odd lingering rainy day early on.
Crowds
Building. Quiet in March, noticeably busier by the warm weekends of May.
Cost
Shoulder, cheaper than summer until prices climb in late spring.

The sweet spot before the heat and the peak crowds arrive, especially May.

Summer

June to August
Weather
Hot and dry, often above 30C in July and August, cooler evenings by the river.
Crowds
Heavy, peaking in July and August, plus the June festival surge.
Cost
Peak. Highest prices and the hardest availability of the year.

June for the festival, but July and August are hot, crowded, and best avoided if you can.

Fall

September to November
Weather
Warm and dry into October, turning cooler and wetter through November.
Crowds
Easing. September still busy, calming nicely by late October.
Cost
Shoulder, dropping back from summer peak as the season goes on.

September and early October match spring for comfort and may even edge it.

Winter

December to February
Weather
Mild for Europe but the wettest stretch, with cool days and the odd cold snap.
Crowds
Low, the quietest months by far outside the holidays.
Cost
Cheapest of the year, with the best deals on rooms.

Bargain prices and empty streets, if you can take the rain risk and shorter days.

Month by month

January
The quietest, cheapest month, cool and prone to rainy spells. Short days, and Sintra's palaces close on January 1, so plan around it.
February
Still low season and still a gamble on rain, but mild between the wet days. Cheap rooms and short, manageable queues at the big sights.
March
Spring stirring, milder and drier as the month goes, though early rain is normal. Crowds are thin, a good value window before the rush.
April
Pleasant and mostly dry, comfortable for the hills. Easter can bring a brief spike in visitors and prices, otherwise an easy time to be here.
May
One of the best months: warm, dry, long days, and not yet packed. Prices are climbing but the comfort-to-crowd ratio is hard to beat.
June
Santo Antonio takes over the city, with street parties, grilled sardines, and packed lanes in Alfama, peaking around June 12 to 13. Lively and warm, but book early.
July
Hot and very busy, often above 30C. The hills are hard work in the heat and queues for the tram and monuments are long all day.
August
Peak heat and peak crowds, plus some local businesses close for holidays. Beautiful but the most demanding month for a city of stairs.
September
The crowds thin and the heat backs off while it stays warm and dry. Arguably the best all-round month to visit Lisbon.
October
Still warm early on, turning cooler and a little wetter late. Lower prices and short queues make it a quietly excellent time to go.
November
The wet season sets in, cooler and grayer, with rain in bursts. Few crowds and low prices reward anyone who packs a jacket and a flexible plan.
December
Mild but the wettest stretch, with festive lights in the center and very low tourist numbers. Sintra's palaces close on December 25.
When we'd go

We would go in late September or in May, and if forced to choose, late September. You get warm, dry days, long evenings, and the city operating at full tilt, but without the July heat that makes climbing to the castle a chore or the August crowds that clog the trams. Prices have eased back from the summer peak, the light is gorgeous, and you can actually get a table. June is the wildcard: if you want the Santo Antonio festival, with sardines smoking on every corner and Alfama dancing until dawn, build the whole trip around mid-June and book months ahead. For everyone else, the shoulder months win on comfort.

When to skip: Skip late July and August if you can. The heat is real in a city you climb on foot, the crowds and prices peak, and some smaller places shut for summer holidays. If those are your only dates, do your sightseeing in the cool early mornings and treat the hot afternoons as time for the aquarium, a long lunch, or the shade.

Best time to visit Lisbon: FAQs

Late spring or early fall, specifically May or September into early October. You get warm, dry weather and long days without the worst of the summer heat and crowds. September is our top pick.

If you want the Santo Antonio street festival, absolutely, it is the city at its most alive, peaking around June 12 to 13. Just know it is busy and book accommodation well ahead. If you would rather skip the crowds, choose May or September instead.

Hot. July and August regularly push past 30C, and that matters more than usual because Lisbon is steep and you walk everywhere. Mornings and evenings are fine, but midday in the sun on the hills is draining.

Not bad, just a trade-off. It is the wettest, grayest stretch with shorter days, but also the cheapest and least crowded, and the temperatures stay mild for Europe. Pack for rain and keep your plans flexible.

The winter months, roughly December through February, outside the holidays, have the lowest room prices and the thinnest crowds. The trade is a real chance of rain and fewer daylight hours.
