Lagos in November: Weather, Sea Temperature and What’s Open

LAGOS · NOVEMBER · 37.1° N

Book Lagos for November and the numbers you are buying are these: an average high of 66.2°F, an average low of 53.1°F, a sea still at 64.4°F, and 10 hours 14 minutes of daylight on the 15th. You are also buying 8.4 days of rain out of thirty, nearly two more wet days than October hands you.

What the month buys back is a coast that works at walking pace. The cliff path above Ponta da Piedade in 66°F air is a different proposition from the same path in high summer, and the Mercado de Escravos on Praça do Infante keeps its full Tuesday-to-Sunday hours. If your dates are still movable, our twelve-month verdict for Portugal argues the other windows, and the cliffs themselves sit in the Ponta da Piedade guide.

Two things do not move with the calendar: the limestone stacks and the shape of the old town. What moves is the water temperature, the length of the afternoon and the list of doors that are open, so those take the space here. The drive in from Faro and the question of where to sleep belong to our Algarve guide.

Lagos weather in November: average highs, lows and rain days

Every figure here comes from IPMA, the Portuguese national weather service, and from a real instrument rather than a model grid cell: station 533 at Sagres, 22.9 m above sea level, 1991 to 2020 normals. It reads 66.2°F by day, 53.1°F at night, 3.23 inches of rain for the month. Sagres is the nearest published station to Lagos and also the windiest headland on the Algarve, so read these as coastal values. Inland and on high ground the air runs colder and a good deal wetter.

Rain lands on 8.4 days of an average November, roughly one day in three and a half carrying at least 0.04 inch (1 mm). Of those, 2.6 days bring 0.39 inch (10 mm) or more, about one day in eleven, and that is the kind that ends a cliff walk rather than interrupting it. Check the threshold before comparing with a US forecast table: IPMA counts from 1 mm, American tables usually start at 0.10 inch, so the two counts are not interchangeable. A seven-night stay should plan around two wet days.

Thirteen degrees separate the afternoon from the dawn, 66.2°F against 53.1°F, and the Atlantic keeps the air damp at both ends of that. Pack a fleece, a light rain shell and shoes with grip, because wet limestone on the cliff path is slick and the descents into the coves are worn smooth. Swim gear still belongs in the bag, along with something warm for dinner after dark. Our packing guide has the full list.

Daylight on November 15 runs 10 hours 14 minutes: sunrise at 7:13 a.m., sunset at 5:27 p.m., with mainland Portugal on UTC all month. Light, not heat, is the binding constraint of a November day here. Anything needing the sun, the cliff path, a boat, an hour on the sand, has to happen between roughly 9:00 and 16:30, and dinner is a night-time event in a town that is dark by six.

Can you swim in Lagos in November? Sea temperature and what it feels like

Sea surface off Lagos averages 64.4°F in November. That number comes from a different source and a different period than the air normals: the Open-Meteo Marine API, 2015 to 2024, and it is the mean of daily maxima rather than a 24-hour mean, so the true all-day average sits a shade below it. On the same basis October reads 66.3°F and December 63.2°F.

At 64.4°F the water is swimmable and unpleasant, in roughly that order. Expect the sharp intake of breath at the waist, ten to fifteen minutes of real swimming (est.) before your hands start reporting back, and a genuine need for a towel and a warm layer in 66°F air afterward. A shorty wetsuit changes the arithmetic entirely and turns the same cove into an hour.

We found no November wind or wave series for Lagos, so no wave heights appear here and we make no promise of flat water for a boat morning. One thing the station notes do tell us: the thermometer sits at Sagres, the windiest point on this coast, and Lagos lies east of that headland, so a breezy reading at the source is not automatically a breezy afternoon in town. Read the marine forecast the night before you book a cliff cruise.

How busy is Lagos in November? Crowds, prices and when to book

November falls outside the summer school holidays on both sides of the Atlantic and outside the Christmas weeks, a calendar fact rather than a price. We could not obtain an occupancy series or a monthly room-rate series for Lagos, so we crown no month cheapest and no month dearest. What the numbers do say is plain enough: 66.2°F afternoons and 8.4 wet days deliver neither a beach week nor a holiday week.

Booking moves for a different reason this month. With 8.4 wet days on the board, a refundable room and a rental car are worth more than an early-bird rate, since the car is what lets you drive out from under a shower. Two to three weeks of lead time (est.) covers a normal November week. The one date worth engineering around is Monday: the Mercado de Escravos is closed, and a Sunday-to-Monday weekend misses it entirely.

We could not verify a tourist tax for Lagos, nor whether one applies in November, so we print no rate and no per-night figure. Ask the property when you book and treat it as an unknown line. Our Portugal cost guide covers what the rest of a week tends to run.

One line of the budget genuinely changes the month, and it is the car. Ten hours of daylight and a shower parked over the coast make mobility the difference between a lost afternoon and a drive west to Praia da Luz. A room with real heating is the runner-up: 53.1°F nights in a building designed to shed August heat feel colder than the number reads.

Things to do in Lagos in November: Mercado de Escravos and Praia da Luz

The water gives up 1.9°F between October and November and another 1.2°F by December, while the air drops 6.1°F over that first step. That gap is what the month does to Lagos: cool enough that the climb back up from a cove is comfortable, warm enough that a swim is still a decision rather than a dare.

The Museu de Lagos is not one building but seven: the main museum, the Dr. José Formosinho collection, the Forte Ponta da Bandeira, the Rota da Escravatura, the Centro de Documentação, the Armazém do Espingardeiro, and the Roman bath house at Praia da Luz west of town. The Rota da Escravatura, signposted as the Mercado de Escravos, stands on Praça do Infante and opens Tuesday to Sunday, 10:00 to 13:00 and 14:00 to 18:00, last admission half an hour before closing.

The Forte Ponta da Bandeira is temporarily closed, and the museum’s own page still said so when it was updated on July 16, 2026. That subtraction stings more in November than in June, because it is one fewer roof over your head on a 0.39-inch rain day. The Mercado de Escravos carries the weight instead: in 2009, a dig at Vale da Gafaria outside the walls, ahead of an underground car park, opened a refuse tip holding more than 150 human skeletons, African people brought to Lagos as merchandise and discarded with the town’s waste.

Nothing in our sources names a free day, a November discount or a winter rate at the museum sites, so we promise none. What costs nothing whatever the date: the cliff path above Ponta da Piedade, the streets inside the old walls, and the sand itself, which you can still reach at 4 p.m. with the sun up until 5:27.

Lagos in November: a two-day itinerary

Day one runs on the light. Coffee at 8:00 while the town climbs toward its 66.2°F ceiling. On the cliff path above Ponta da Piedade from 9:00 to noon, low sun behind you and the rock dry. Lunch at 13:00, which is also the hour the Mercado de Escravos shuts. Praça do Infante at 14:00, ninety minutes inside, out by 16:00. Back on the seafront for the 5:27 p.m. sunset, dinner at 19:00 in air heading down to 53.1°F.

Day two starts in the water or not at all, because 64.4°F is a morning decision and the Atlantic will not be warmer at 3 p.m. Then drive west to Praia da Luz for the Balneário Romano, the museum’s Roman bath house, and confirm its hours with the museum before you set off. If the sky is one of the 2.6 heavy days, invert the plan: museum sites and the Formosinho collection in the morning, the coast walk shifted to whichever half-day clears. Not Monday, though.

Lagos in November vs October and December

Read the table down the temperature row and November is the middle child: 6.1°F cooler by day than October, 3.6°F warmer than December. The rain row is where the slope breaks, because November is the wettest of the three at 3.23 inches across 8.4 wet days, ahead of December’s 2.96 inches across 8.0. The sea steps down evenly, 66.3°F, 64.4°F, 63.2°F, all three on the marine API’s daily-maxima basis.

Shift back four weeks and October returns 6.1°F of afternoon, 1.9°F of water and nearly two fewer wet days, at the cost of sharing the coast with the tail of the season. Shift forward and December takes 3.6°F off the day and 1.2°F off the sea, gives back four-tenths of a wet day, and adds closures to the calendar: the Rota da Escravatura shuts on December 1, 24 and 25.

Is November a good time to visit Lagos?

Yes for walkers, for museum days and for anyone whose trip survives two wet days in seven. Lagos in November gives 66.2°F afternoons, a town moving at its own pace, and water you can still swim if you are the swimming sort. No for a beach week, no for a family that needs a warm pool, and no for anyone whose plan hinges on the Forte Ponta da Bandeira, closed until further notice.

If the answer came out no, October is the month to buy: 72.3°F by day, 59.0°F at night, a 66.3°F sea and 6.7 wet days instead of 8.4. It costs you the quiet and it sits nearer the season, but of the three months here it is the one where the beach is the point rather than the backdrop.

Of those three, only November sets a sea above 64°F next to afternoons that stay under 70, the combination for walking a coast all day and still getting wet at the end of it.

The last word

Decide the car first and the room second: with the light gone at 5:27 p.m. and rain on roughly one day in three and a half, mobility is what rescues a November afternoon. Then put the Mercado de Escravos on a mid-afternoon that is not a Monday, and accept that the Forte Ponta da Bandeira stays behind its drawbridge for now. Its moat, its 1680s artillery walls and the small azulejo-lined chapel inside are not going anywhere, and neither are the cylindrical sentry boxes a restoration added around 1960.
