Lisbon in October: Weather, Crowds and What to Actually Pack (2026)

On Saturday 24 October 2026 the sun sets over Lisbon at 18:47. On Sunday the 25th it sets at 17:46. Nothing about the weather changes overnight, only the clocks, and yet the whole shape of a Lisbon evening moves with them.

That single hour is the thing most October guides forget to mention, and it decides whether your sunset at a miradouro (a hilltop viewpoint) happens before or after dinner. October is a good month here, arguably the last genuinely warm one, with sea still warmer than it was in June and the summer crowds thinned out. It also carries the year's first real rain and the shortest evenings you have seen since spring.

So here is what October actually looks like in Lisbon: the numbers, the rain, what to put in the bag, and the dates worth planning around.

What Is the Weather Like in Lisbon in October?

October in Lisbon averages a high of 22.5°C and a low of 15.1°C, with about 100 mm of rain over roughly ten days.

Those figures come from IPMA, Portugal's weather service, and they hide a split down the middle of the month that averages cannot show you. The first two weeks usually behave like a late and gentle September, with dry days, high sun and terraces still full at nine in the evening. The last two weeks are where outono (autumn) actually arrives, bringing the first Atlantic fronts, cooler nights and a sun that sits noticeably lower in the sky.

For scale, our own month-by-month figures put September highs near 27°C and November near 18°C, so October sits exactly on the hinge between them and inherits a little of each. One thing changes for the better: the nortada, the northerly wind that hammers this coast all summer, eases through autumn, so the seafront and the beaches are calmer than they were in August. The humidity drops too, which is why 22°C in October can feel warmer on the skin than the same reading in May. For the full year in context, see our guide to the best time to visit Lisbon.

The Rain: Ten Wet Days, Twenty-One Dry Ones

Everyone quotes the ten rainy days and nobody does the subtraction. October has about 21 days without rain, and even the wet ones rarely rain all day.

Atlantic rain in Lisbon works in bursts. A front comes through, dumps hard for an hour or two, and then the sky opens again and the calçada (the polished limestone mosaic pavement) steams dry in the sun. Locals do not cancel their day for it; they duck into a café and wait it out. An umbrella is close to useless when the wind picks up, so a packable hooded shell earns its space in the bag.

Local tip: watch the shoes rather than the sky. Wet calçada is genuinely slippery, and Lisbon's hills turn those pretty pavements into a skating rink after a downpour. Grip matters more than waterproofing here.

For the afternoon that does settle in, the city has a strong indoor bench: the tile museum, the Gulbenkian, the oceanarium and a long lunch in a tasca (a plain neighbourhood tavern) all work better in October than they ever do in August, because nobody is queuing. Our where to eat in Lisbon guide has the tables worth crossing town for, and a walking tour is easy enough to rebook a day either side of a front.

What to Wear in Lisbon in October

This is the most-asked question of the whole month, and the answer is layers rather than warm clothes.

A October day in Lisbon can start at 15°C in the shade, reach 23°C on a sunny south-facing street by three in the afternoon, and drop back to the low teens once the sun goes. Dress for the middle and carry the edges. In practice that means a t-shirt or light shirt, a jumper or overshirt you can tie round your waist, and a light rain shell that packs down small.

Bring one thing people forget: proper walking shoes with grip. The other thing people overpack: a heavy coat, which you will not need. Sunglasses and sunscreen still earn their place, because the October sun sits lower and comes straight at your eyes on a west-facing street.

If you are eating outside in the evening, take the extra layer. An esplanada (a pavement café terrace) that felt perfect at seven can be cold by ten, and the riverside is always a couple of degrees cooler than the sheltered streets of the Baixa grid.

Planning tip: pack for two seasons in the same suitcase and check the forecast the day you arrive rather than the week before. Atlantic weather here changes on a three-day horizon, and anything further out is guesswork.

The Hour Lisbon Loses on 25 October

Portugal puts the clocks back at 2am on Sunday 25 October 2026, and it changes the day more than the temperature does.

Book a sunset for 19:00 in the third week of October and you will be an hour late for it in the fourth. After the 25th, golden hour at Senhora do Monte or Santa Catarina lands before 18:00, which puts it before dinner rather than after.

The upside is the mornings. From the 26th, sunrise comes back to just after 7am, so the light on the river is usable at a civilised hour and the famous viewpoints are empty. If your trip straddles the change, put the sunset plans in the first half and the sunrise plans in the second.

Can You Swim in Lisbon in October?

Yes, especially in the first half of the month. The sea off Lisbon averages 19.8°C in October, warmer than it is in June, because the Atlantic runs about two months behind the air.

The catch is everything around the water. Lifeguard cover ends with the bathing season, the afternoons shorten, and a cloudy day at 20°C makes the walk back to the train feel a lot longer than the same walk did in August, so bring a towel you can actually dry off with.

Carcavelos is the easy one, a 30-minute train from Cais do Sodré to a wide sheltered beach with cafés that stay open year-round. Costa da Caparica keeps its long Atlantic sand and a handful of beach bars trading well into autumn, and the buses from Cacilhas run on the normal timetable. Guincho turns into a place for watching rather than swimming by October, when the swell returns and the surfers take the water back. Our beaches near Lisbon guide covers the four coasts, with deeper guides to Costa da Caparica and Praia do Guincho.

Local tip: go swimming before lunch rather than after. The wind builds through the afternoon on every one of these beaches, and by four o'clock in late October the difference between a pleasant hour on the sand and a cold one is entirely down to timing.

Is Lisbon Busy and Expensive in October?

Less of both than summer, and the drop is steepest after the middle of the month.

The first half still feels busy, because the shoulder season is no secret and the weather is reliably good. Queues at Jerónimos and Belém Tower are real but shorter, and Sintra becomes genuinely pleasant instead of a heat trap. From about the 20th, the city empties in a way you can feel: tables free up, tram 28 has seats, and the Lisboetas (people of Lisbon) get their own streets back.

Prices follow the same curve. October sits well below the July and August peak, and the second half of the month is the best value in the whole warm half of the year, with rooms often a third cheaper than the same bed in August. Flights soften in the same window, though the half-term break in the last week pulls British and Irish demand back up. Two weekends buck the trend, so book early if your dates land on them: marathon weekend on 10 and 11 October, and the closing weekend of Doclisboa.

Restaurants are the other thing that changes. Kitchens that spent the summer turning tables in forty minutes slow down again, which means the places that would not take a booking in August will happily seat you in late October, and the seasonal menus turn towards soups, game and the year's new wine.

Day Trips That Work Better in October

Some of the classic trips out of Lisbon are simply better in October than at any other time, because they were miserable in the heat.

Sintra is the clearest case. The palaces sit in a damp micro-climate on a wooded ridge, and the walk up to Pena in August is a punishment. In October the hill is cool, the queues are half what they were, and the mist that gives Sintra its atmosphere actually shows up. Take a jacket, because it is reliably several degrees colder up there than in the city, and see our Sintra day trip guide for the route.

Wine country is the other October speciality. The harvest runs from late September into October across the hills around Lisbon and the Tagus, so the cellars are working rather than posing, and the vines turn colour on the drive.

Detour: the Arrábida hills south of the river pair a harvest visit with an empty beach. The water there is sheltered and calm long after the exposed Atlantic beaches have turned rough, which makes it one of the few places you can still swim comfortably in the last week of October.

What's On in October 2026

• 5 October, Implantação da República. A national public holiday marking the founding of the Republic in 1910. Public services close, most shops and restaurants do not.
• 10 and 11 October, EDP Lisbon Marathon. The marathon runs on the Saturday, starting at 08:00 from Carcavelos, with the half marathon and 8K on the Sunday. Both finish at Praça do Comércio, and the riverside roads close for most of both mornings, so plan Belém for a different day.
• 13 October, Fátima pilgrimage. The anniversary of the 1917 "Miracle of the Sun" draws enormous crowds to the sanctuary, with a candlelit procession the evening before. It is a day trip north of the city, and the coaches book out well in advance.
• 15 to 25 October, Doclisboa. The 24th edition of the city's international documentary festival, spread across several cinemas, with a good share of the programme subtitled in English.
• All month, chestnut season. The castanhas assadas (roasted chestnuts) carts return to street corners through October, ahead of São Martinho on 11 November. A paper cone costs a couple of euros and warms your hands on the walk home.

Planning tip: book the marathon weekend or avoid it deliberately. Hotels near the finish at Praça do Comércio fill months ahead, and the closures make Belém, the riverside tram and the ferry crossings awkward on both mornings.

One honest note on the fashion calendar. Lisbon Fashion Week has traditionally taken an early-October slot, but the 66th edition ran in March 2026 and no autumn 2026 dates had been announced as of July 2026. Several guides list it as fixed; treat it as unconfirmed until the organisers say otherwise.

Practical Tips

• Check the clock change against your dates. Sunset moves from 18:47 to 17:46 on 25 October 2026.
• Take a packable rain shell, not an umbrella. The wind that comes with Atlantic fronts turns umbrellas inside out.
• Wear shoes with grip. Wet calçada on a Lisbon hill is the most common way visitors hurt themselves here.
• Book Sintra and Belém for weekdays. October weekends still fill, and both are far better without the summer heat.
• Avoid the riverside on 10 and 11 October unless you are there for the marathon.
• *Order caldo verde** (the kale and potato soup) once the evenings turn. It is the taste of the season, and every tasca* makes it.

FAQ

Is October a good time to visit Lisbon?

Yes, and it is one of the best-value warm months. You get daytime highs around 22.5°C, a sea still warm enough to swim in, thinner crowds than summer and lower prices, in exchange for a real chance of rain and much shorter evenings.

How rainy is Lisbon in October?

About 100 mm falls across roughly ten days, which leaves around 21 dry days. The rain tends to arrive in short heavy bursts rather than lasting all day, and it is more likely in the second half of the month.

What should I wear in Lisbon in October?

Layers. A light top, a jumper or overshirt, and a packable rain jacket cover almost every day, plus walking shoes with grip for the wet pavements. Leave the heavy coat at home and bring sunglasses.

Is Lisbon busy in October?

Moderately in the first half, noticeably quieter in the second. Queues at the big Belém monuments are shorter than in summer, and after about the 20th the city feels like it belongs to its residents again.

Is Lisbon or Porto warmer in October?

Lisbon, by a couple of degrees. Porto sits further north and takes the Atlantic fronts earlier and harder, so it is both cooler and wetter through autumn.

What time does the sun set in Lisbon in October?

It moves fast: 19:21 on 1 October, 18:47 on the 24th, then 17:46 on the 25th once the clocks go back, and 17:38 by the 31st.

Booking the Right Half of the Month

If you want warmth, sea and long evenings, come in the first half and accept that you are sharing the city. If you want quiet streets, cheap rooms and the best light of the year for photographs, come in the last week and carry a jacket.

Either way, October rewards a loose plan. Keep one indoor day in reserve for the front that will probably arrive, put your miradouro evenings on the right side of the 25th, and the month will treat you well.
