The Best Time to Visit Lisbon (and When I’d Avoid)

There is no single perfect month to visit Lisbon, but there is one time of year I would avoid if I had the choice: peak summer.

I spent the end of August and start of September in Lisbon on my most recent trip, and I genuinely loved it. But after days of walking steep streets in the heat and sharing the city with plenty of other visitors, I also came home with a much clearer idea of when I would go next time.

If you are trying to balance good weather, smaller crowds and reasonable prices, this guide will help you choose the best time to visit Lisbon for your trip, plus the months I think are worth avoiding.

The Best Time to Visit Lisbon, Overall

My honest answer is spring or autumn, and this is advice I’d give for most of Europe’s warmer cities, not just Lisbon specifically.

You get warm, comfortable days without the punishing heat, fewer crowds at the big sights, and a city that feels like it’s actually being lived in rather than just visited.

Even winter has a certain charm here, which surprised me, since Lisbon doesn’t shut down the way some northern European cities do in the colder months.

If you’re building out a full trip, I’d pair whichever season you choose with my 3 days in lisbon itinerary, since most of it works comfortably in any of the seasons I’m about to walk through.

Whichever season you land in, the list of things to do in Lisbon barely changes, though which best neighbourhoods in Lisbon feel liveliest does shift with the crowds.

What Lisbon Is Like in Late Summer

Late August into early September was busy, but not unbearably so, and the weather was warm during the day, dropping noticeably once the sun went down.

Daytime highs in Lisbon through summer regularly sit around 28°C, and it can push higher during a proper heatwave, so the heat is genuinely no joke!

One thing nobody warned me about: Lisbon’s pavement, the classic calçada portuguesa tiles, gets seriously slippery once it’s hot, and even more so if it’s been wet, closer to walking on ice than pavement.

My Birkenstocks, which grip fine everywhere else I’ve worn them, were genuinely hopeless here, while a €15 pair of sandals I’d bought in Albania ended up being the only footwear that actually held on the hills.

Late summer is also when petty theft ticks up in the busiest squares, worth knowing before you decide whether Lisbon is safe enough to relax in.

Why Spring and Autumn Are My Pick

Spring and autumn spread the crowds out, cool the temperatures down to something more comfortable for a full day of walking, and still leave plenty of daylight for sightseeing.

This matters more in a city like Lisbon than in a flatter one, because so much of getting around here involves climbing hills, and doing that in 28°C heat with a crowd of cruise ship day-trippers is genuinely less fun.

I’ve written more about why the shoulder seasons work so well for the wider question of is lisbon worth visiting, since timing plays a real part in how much you enjoy the city overall.

Lisbon’s own calendar of events is worth checking too, since festival dates shift year to year and can shape which week you’d actually want to book.

It is also easier to get a table at the best restaurants in Lisbon I would actually recommend without booking weeks ahead, and easier to land a room in whichever area I suggest in where I would actually stay in Lisbon.

Is Winter in Lisbon Worth Considering?

Winter in Lisbon is genuinely mild by European standards, with daytime highs typically sitting somewhere around 15°C, so you’re not dealing with anything close to a harsh northern winter.

Rain is more likely this time of year, and a wet day does make those same slippery tiles worse, so I’d still pack proper grip regardless of season.

What you get in return is noticeably lower prices, thinner crowds at places like Fronteira Palace, and a city that still has plenty going on despite the cooler weather.

I wouldn’t call it the best time to visit, but I’d genuinely consider it if crowds and cost matter more to you than warm evenings outside.

The Eating Europe food tour still runs through winter, just with a smaller group.

What to Pack for Lisbon’s Weather

Grippy shoes are non-negotiable here, whatever the season, because those tiles do not care how confident you feel in your sandals.

If you’re visiting in summer, bring a hat, sun cream, and something to keep you cool, a handheld fan sounds excessive until you’re standing in direct sun on a Lisbon hill at 2pm.

Stay properly hydrated, that’s the single most important thing regardless of when you visit, and Lisbon’s own traveller information page has a decent general packing and practical tips section if you want more.

Even in the height of summer, evenings cool down enough that you’ll want a light layer on hand, especially if you’re heading up to a miradouro for sunset the way I did.

Whatever season you land in, pack for hills, sun, and the possibility of rain, and you’ll be set!

If you are arriving via Porto, the bus down is comfortable regardless of season, here is how I actually got from Porto to Lisbon.
