What's the weather like in the Algarve in December?
Christmas lights go up along the pedestrian streets of Faro and Lagos, and the café terraces are still setting out tables at lunchtime. December is the Algarve at its most local: winter market stalls selling roasted chestnuts, restaurants filled with Portuguese families rather than tourists, and that particular quality of low winter light that turns the limestone cliffs golden in the late afternoon.
The weather is a mix of crisp, sunny days and Atlantic rain fronts that blow through in a day or two. You won't get a heatwave, but you'll spend more time outdoors than you would anywhere in northern Europe. The pace is slow, the prices are low, and the region feels like it belongs to the people who live here.
Temperature
Mornings start cool enough for a proper jacket and a layer underneath until around 10am. By midday on a clear day, sheltered spots along the south coast feel warm enough to sit outside comfortably. The sun is low, so shade is noticeably colder than direct sunlight, and the difference matters when choosing a restaurant terrace.
The eastern Algarve around Tavira and the Ria Formosa tends to be slightly milder and more sheltered. The west coast around Sagres runs cooler with more wind. Inland, particularly around Monchique, temperatures drop further at night, and frost is possible above 400 metres.
Sunshine and rainfall
The useful daylight runs from about 8am to 5:30pm. Short days, but the morning light comes in clean and sharp. On clear days the sun has real warmth to it, and you'll want sunglasses more than you'd expect for December.
Rain arrives in distinct episodes: a day or two of heavy showers followed by several dry, bright days. It's not the relentless grey of a British winter. When a front passes through, it moves on, and the sky behind it is often vivid blue. Carry a waterproof jacket and don't let a rainy forecast cancel your plans — check the hourly outlook and you'll usually find a window.
Sea temperature and swimming
The Atlantic is at its coolest, and this is not a swimming month for most visitors. Wading and beach walking are pleasant on calm days, but getting fully in takes commitment. The south coast beaches are calmer, and on a sunny morning Praia da Luz or Praia da Salema can feel inviting from the sand, even if the water tells a different story.
Surfers have the best of it. The west coast picks up powerful Atlantic swells, and Praia do Amado and Praia de Arrifana deliver consistent winter surf with barely anyone in the water. A good 4/3mm wetsuit makes December sessions comfortable. Several surf schools in Sagres and Aljezur run year-round.
Wind and conditions
Atlantic fronts are the dominant weather pattern, rolling in from the west every few days. These bring rain, gusty winds, and sometimes dramatic seas — the kind of weather that makes the western cliffs spectacular to watch from a safe distance. Between fronts, conditions settle quickly into calm, clear days.
The Nortada is dormant in December, so when it's not raining, conditions are often still and mild. Levante episodes are rare but possible, bringing a few unusually warm, hazy days. Golf, hiking, and coastal walks are comfortable on any dry day.
What to pack for December in the Algarve
- A proper jacket and warm layers: fleece or jumper, plus a scarf for evenings
- A waterproof coat you'd actually wear in heavy rain, not just a light shell
- Comfortable walking shoes with grip for potentially wet trails
- Sunglasses for the low winter sun, which is surprisingly bright
- An umbrella for town, though wind makes it useless on the coast
- Swimwear only if your hotel has a heated pool
Events and seasonal highlights
Loulé's Christmas market is the biggest in the region, filling the town's covered market and surrounding streets with crafts, food stalls, and live music through December. Lagos and Faro both put up festive lights and host smaller markets. These are local affairs, not the polished commercial markets of central Europe, and they're better for it.
New Year's Eve brings fireworks along the coast, with displays in Faro, Portimão, Albufeira, and Lagos. Restaurants put on special menus, and the mild temperatures mean you can watch the midnight fireworks outdoors in a light jacket.
Birdwatching is at its winter peak. The Ria Formosa Natural Park and Castro Marim salt pans host overwintering flamingos, spoonbills, and waders. Early mornings on the lagoon are particularly rewarding.
Why visit the Algarve in December?
December is the cheapest month to visit the Algarve. Hotel rates drop to a fraction of summer prices, flights are inexpensive, and you'll have popular restaurants and attractions almost to yourself. If mild weather, quiet surroundings, and low costs matter more to you than beach days and warm seas, December delivers.
The honest downsides: days are short, the sea is cold, and some seasonal businesses close for winter. A few beach restaurants and water sports operators shut down between November and March. Rain will interrupt at least a couple of days, and evenings are cool enough that you'll want to eat indoors. This is not a beach holiday month.
For golfers, hikers, and birdwatchers, December is genuinely excellent. Golf courses are quiet and green fees are at their lowest. Coastal paths are lush and uncrowded. And if you want to experience a Portuguese Christmas — with bacalhau on Christmas Eve, bolo rei in every bakery, and midnight mass in a whitewashed village church — the Algarve is a warmer place to do it than Lisbon.

Daytime temperatures sit in the mid-teens on most days. In direct sun and out of the wind, it feels warmer — comfortable enough for lunch on a terrace. Mornings and evenings are cool, typically around 9–10°C, and you'll want a proper jacket after dark.
Does it rain much in December?
December averages around 8 rainy days, but the rain comes in bursts rather than all-day drizzle. You'll typically get a day or two of showers followed by several dry, sunny days. A waterproof jacket is essential, but rain rarely ruins a full day.
