NAZARÉ · OCTOBER · WEATHER AND SEA
October is the month the Atlantic finally catches up with the calendar at Nazaré. The air has stepped down from its summer high to an average 67.3°F, the sun still clears the headland at a civilized hour, and the sea, warmed all summer and slow to let go, sits at 65.8°F: warmer than it was in September, warmer than it will be in November.
What the month takes back is the sky. September records rain on 4.1 days and October on 9.2, and the rainfall total goes from 0.99 inch to 3.33. Daylight is down to 11 hours 13 minutes by mid-month. This is a good month for a swim, a long clifftop walk and a cancelable booking, in that order.
THE MONTH AT A GLANCE · NAZARÉ · OCTOBER
October hands Nazaré the warmest sea of its autumn, 65.8°F, with highs still at 67.3°F and measurable rain on about three days in ten, so come for the water and the empty promenade and book a room you can cancel.
IPMA 1991–2020 NORMALS · STATION 531, CABO CARVOEIRO · SEA FROM DAILY MAXIMA, 2015–2024
Go for: the warmest water of the September-to-November window, a beach promenade without the August queue, and a clifftop sunset that arrives before dinner rather than after it.
Think twice before: counting on beach weather. Wet days more than double from September, and 2.8 days of the month bring 0.39 inch or more.

Nazaré weather in October: average highs, lows and rain days
| Measure | October | Source and period |
|---|---|---|
| Average high | 67.3°F (19.6°C) | IPMA normals, 1991–2020 |
| Average low | 59.5°F (15.3°C) | IPMA normals, 1991–2020 |
| Rainfall | 3.33 in | IPMA normals, 1991–2020 |
| Days with 0.04 in or more | 9.2 | IPMA normals, 1991–2020 |
| Days with 0.39 in or more | 2.8 | IPMA normals, 1991–2020 |
| Sea surface, mean of daily maxima | 65.8°F (18.8°C) | Open-Meteo Marine, 2015–2024 |
| Daylight on October 15 | 11 h 13 min | sunrise-sunset.org |
Every figure here comes from IPMA, the Portuguese weather and sea service, and from one instrument in particular: station 531 at Cabo Carvoeiro, Peniche, a real thermometer 32 meters (105 feet) up on the same exposed stretch of coast, reading the 1991 to 2020 normals. October averages a high of 67.3°F and a low of 59.5°F, with 3.33 inches of rain. That describes the shoreline and nothing else. Move inland and uphill and the numbers change, because high ground is colder and a great deal wetter.
Rain reaches the gauge on 9.2 days of an average October, which works out at roughly three days in ten. Serious rain is much rarer: 2.8 days cross 0.39 inch, about one day in eleven. Before you set that beside an American forecast table, note the thresholds. IPMA counts from 1 mm (0.04 inch), not from the 0.10 inch used in US tables, so the two wet-day counts are not interchangeable and October will look wetter here than it would there.
The ocean keeps day and night close together: 7.8°F separates the average high from the average low. That small spread is pleasant and slightly misleading. An evening at 59.5°F on an open headland, with wind coming straight off the water, is colder than the thermometer suggests. Pack a windproof shell over a fleece and a pair of shoes you can walk wet cobbles in, and you have covered the month. Our packing guide handles the rest of the suitcase.
Light is the other thing October withdraws. On the 15th the sun rises at 7:46 a.m. and sets at 6:59 p.m. local time, giving 11 hours 13 minutes of daylight. In practice the useful beach window runs from mid-morning to about five, and the clifftop at Sítio turns golden and then cold within twenty minutes of sunset. Dinner in Portugal starts late enough that you can watch the whole thing and still be at a table by eight.
Can you swim in Nazaré in October? Sea temperature and what it feels like
Yes, and better than in September. The Open-Meteo marine series puts the sea surface off Nazaré at 65.8°F (18.8°C) in October, averaged across 2015 to 2024. Read that number for exactly what it is: a mean of daily maxima, so a shade warmer than a 24-hour average would come out. The same series gives September 62.9°F and November 63.7°F. October is the warmest water of the three, by a clear margin over the month everyone assumes is warmer.
Now the practical translation. At 65.8°F the first thirty seconds are a shock and the next ten minutes are fine, which is the honest description of most Atlantic swimming in Portugal. Unwetsuited swimmers get a proper dip rather than a lounging session. A wetsuit turns that dip into an hour, and the surf schools along the bay beach rent them. Dry off fast: 59.5°F air and a sea breeze undo a warm body quicker than the water did.
On swell and wind we have to stop short. We could not verify an October wave-height or wind record for Nazaré, so no figures appear from us. What is not in dispute is the geography: the giant waves that made Praia do Norte famous belong to the winter storm months and to the submarine canyon that focuses them, while the bay beach tucked under the headland is the sheltered side of the same town. Lifeguard cover outside high summer we also could not confirm.
How busy is Nazaré in October? Crowds, prices and the demand peak
October is a shoulder month by the calendar: Portuguese schools are back, the July and August beach population has gone home, and the winter big-wave circus has not yet arrived. That is a statement about dates, not about money. We found no occupancy series and no monthly room-rate series for Nazaré, so we crown no month cheap and no month expensive, and any figure you see us give on this subject would be invented.
On how far ahead to book, the same restraint applies: we could not verify a lead-time figure and will not manufacture one. What we will push is the refundable rate. With rain on 9.2 days of an average October, the ability to move a night costs less than the night you would otherwise waste indoors. Our trip-cost guide holds the country-level budget picture, and the where-to-stay guide covers the regional choices.
A tourist tax comes up in every Portugal thread. We could not verify a municipal rate for Nazaré, so we quote none. Several Portuguese municipalities do levy a per-person, per-night charge collected at check-in, and the only reliable way to know yours is to ask the property at booking. Treat any number you read elsewhere, ours included, as unconfirmed until the front desk says it.
There is one upgrade that genuinely changes October, and it is the car. Three days in ten arrive wet, and a wet morning in a beach town is a short story. With a car it becomes the walled lanes of Óbidos or a monastery interior, and you are back on the promenade by four when the sky clears. Our rental guide covers tolls and the paperwork.
Things to do in Nazaré in October
Of September, October and November, only October pairs the warmest water of the three, 65.8°F, with air still above 67°F at midday. September has the drier sky but colder water at 62.9°F. November has 10.5 wet days and a 62.6°F high. The combination that makes October its own month is a swimmable sea under an autumn sun, on sand you can cross without stepping over anyone.
The town splits in two and both halves want a morning. Praia da Nazaré is the long bay beach below the old fishing quarter, with its promenade and its drying racks. Sítio is the village on the headland above it, reached by the funicular that climbs the cliff face, with the Suberco viewpoint looking straight down on the sand. North of the headland lie Praia do Norte and the Forte de São Miguel Arcanjo, lighthouse and big-wave exhibition in one. Fares and opening hours we could not verify, so check them on the spot.
What the date changes at those places is the air, not the water. From September to November the average high falls 7.0°F, from 69.6°F to 62.6°F, while the sea moves less than 3°F across the whole span, 62.9 to 65.8 to 63.7. So the swim barely notices the season and the clifftop notices nothing else. On the Suberco terrace in October you need the jacket you did not carry in August.
The best of the month is free. Walking the beach promenade end to end, the esplanade and viewpoint at Sítio, the cliff path toward the lighthouse, and a 6:59 p.m. sunset from the headland on October 15: none of it has a ticket desk. Where a ticket exists, at the fort and on the funicular, we have no verified price to give you, and we would rather say so than guess.
Nazaré in October: a two-day itinerary
Day one, in the bay. The sun is up at 7:46 a.m., so coffee at eight costs you nothing. Take the promenade from nine to eleven while the light is low on the sand. Swim close to midday, when the air is at its 67.3°F best and the 65.8°F water feels least unreasonable. Lunch at one. Ride the funicular up at three, walk Sítio slowly, and be at the Suberco viewpoint by half past six for a 6:59 p.m. sunset.
Day two, on the north side. Morning at Praia do Norte and the Forte de São Miguel Arcanjo, then back down for a late lunch and an afternoon on the beach. If the day is one of the 9.2 wet ones, flip it: drive inland to Óbidos for the morning and keep the coast for the clearing. With 2.8 days a month bringing 0.39 inch or more, one October visit in a fortnight meets a genuinely lost afternoon.
Nazaré in October vs September and November
| Measure | September | October | November |
|---|---|---|---|
| Average high | 69.6°F | 67.3°F | 62.6°F |
| Average low | 62.1°F | 59.5°F | 55.0°F |
| Rainfall | 0.99 in | 3.33 in | 3.86 in |
| Days with 0.04 in or more | 4.1 | 9.2 | 10.5 |
| Sea surface, mean of daily maxima | 62.9°F | 65.8°F | 63.7°F |
October sits 2.3°F below September on the daytime high and 4.7°F above November. Rain is where the three months separate: 0.99 inch in September, 3.33 in October, 3.86 in November, with wet days going 4.1, then 9.2, then 10.5. The sea runs against that slope. It peaks in October at 65.8°F, 2.9°F above September, and the air normals come from IPMA while the water comes from the Open-Meteo marine series, two different instruments telling one story.
Shift back four weeks and you buy a dry sky, five fewer wet days and 2.3°F more warmth at midday, and you pay for it with water at 62.9°F and the tail of the summer season. Shift forward and November hands you 10.5 wet days, 55.0°F nights and a shorter afternoon, in exchange for a coast that starts to look like its winter self. The full cases sit on the September page and the November page.
Is October a good time to visit Nazaré?
For swimmers, walkers and anyone who wants the promenade to themselves, yes without hesitation: this is the warmest sea of the autumn and the air is still doing 67.3°F at midday. For a family with one week and a beach-only plan, no. Rain on three days in ten, with 2.8 of them heavy, is not a beach week, and nothing about a small Atlantic town improves when the sky closes in for two days running.
If that second description is you, take September. It averages 0.99 inch of rain across 4.1 wet days, the high sits at 69.6°F, and the nights stay at 62.1°F rather than dropping to 59.5. The concession is the water at 62.9°F, nearly 3°F colder than October, and company on the sand. For surf watching rather than swimming, keep going and read November.
No other month puts a 65.8°F sea, a 67.3°F afternoon and an emptied beach town in the same week.
The last word
Decide on the water, not the forecast. If a swim in the Atlantic is part of why you are coming to Nazaré, October is the month of the three that gives it to you, and the arithmetic behind the gloom is friendlier than it sounds: 9.2 wet days out of 31 leaves roughly 22 days with nothing measurable in the gauge at all. Book a room you can cancel, carry the shell, and let the funicular do the climbing.
