The best times to visit Lisbon, in my opinion, are March to June, and September to November. But you can visit Lisbon any time of the year. The worst time is August, at least if you want to have some space to yourself.

Since I’ve lived in Lisbon for a few years now, so I can offer some first-hand information on the best time to visit. Be sure to also check out my guide to the best things to do in Lisbon.

Visiting Lisbon in winter

Is winter the best time to visit Portugal? Objectively speaking, it’s probably not. But is it a good time to visit? Definitely! In fact, I highly recommend coming in winter.

As long as it’s not raining (keep an eye on the weather reports), you’ll enjoy mild temperatures and an unhurried atmosphere. It might well be the best time for a cultural city break that’s not just all about catching some sun.

December and January can get rainy sometimes, but there are also fewer tourists, which makes it easier to have a more personal and unhurried experience. You may get onto Tram 28 without queuing for ages!

Lisbon in late January – still plenty of bright days to enjoy

Rainy days are a possibility but there are countless museums and historical buildings you can visit, not to mention the largest indoor aquarium in Europe.

On most days, you can still sit outside while wearing a summer coat and enjoy a ginjina (cherry liquor) or vinho verde (green wine) at one of Lisbon’s typical koisks. The castles of Sintra are amazing in winter as there are fewer people in your way, although the Quinta da Regaleira gardens are better when there are more leaves on the trees.

I’ve been to both Lisbon and Porto in winter and I can recommend either city if you’re looking for a low-key escape from the harsher northern winters. Even in the heart of winter, Portugal is a bright and light place that will make you easily forget the darkness of northern Europe.

Visiting Lisbon in spring

This is an excellent time to visit, and arguably the best time of the year. The average number of rainy days drops from around 12 in March and April, to 8 in May and just 5 in June.

If you’re lucky, you can already feel like you’re in summer at the start of spring. This year I had my first beach day in mid March, when on one day temperatures reached 26 degrees C. In April, I already spent time around the beaches in the Algarve in the south of Portugal, though realistically most weeks were still too cold for beaches, with the warm season kicking off in earnest in May.

From about late April or early May, the city of Lisbon is at its most beautiful time of the year, as Jacaranda trees begin to blossom and many of its squares and avenues turn purple. Outdoor activities begin to dominate the city life again, with people having drinks outside in the cobbled streets of Barrio Alto and along the Tagus river.

You may also want to visit Lisbon in June, as this is a month filled with festivities around the Popular Saints. There is music in the streets, colorful buntings everywhere, and vendors selling grilled sardines.

The biggest night is St. Anthony’s day (early June) and the week leading up to it is a pretty big deal as well, though the entire month sees all sorts of festivities.

Visiting Lisbon in summer

Summer is a beautiful time to visit, especially if you’re keen on going to the beach!

Keep in mind the Atlantic waters around Lisbon are very cold even in summer, but the air temperatures reach the right levels to properly enjoy those icey baths. Day time temperatures will regularly reach up to 35°C.

As anywhere in Europe, it makes sense to avoid the month of August if you can. For some people this is the only time to take a holiday, but if you have any flexibility, the other months will give you a better experience. In August, the beaches around Lisbon are packed. Lisbon arguably suffers from overtourism in the months of July and August in particular, and the center becomes a hectic and manic tourist trap. During the peak of summer, you may have a better time exploring the rest of Portugal instead.

Visiting Lisbon in autumn

Autumn can be a lovely time to visit. You can have bright and pleasant days well into October and even November. You can walk around in just a t-shirt or a light summer coat.

It’s especially a great time to visit Sintra, where the gardens of Quinta de Regaleira become even more photogenic thanks to the colourful leaves and the late afternoon autumn glow from the sun.

The biggest crowds have passed now, so you can have a less hurried time in Lisbon. If you’re looking to go out in Barrio Alto or Pink Street, you’ll find the streets much more easy to navigate, and a more chilled out atmosphere outside of the bars.

Avoiding the crowds

  • You may wish to avoid the week of Web Summit, an international conference attracting over 60,000 attendees, at least if you’re intending to go out in the center (as restaurants and bars get flooded with conference attendees).
  • The historical area of Alfama can be very busy on days when multiple cruise ships happen to be docked there. Cruise schedules here.
