The Algarve: The Reliable Winter Base
The Algarve in December is the most dependable retreat destination in Portugal at this time of year and the one most worth choosing if warmth and reliability are the priority. Average daily highs of 16-18°C, over 300 days of sun per year meaning December is mostly clear, and the Atlantic surf on the western coast at its most powerful. Retreat centres that stay open through December in the Algarve do so because the format works — the groups are small, the atmosphere is intimate, and outdoor morning practice in the December Algarve sun is possible in a way that no northern European destination can offer.
The western Algarve around Sagres and Aljezur is in December at the peak of its surf season. The North Atlantic storm systems that generate the best waves are at full December intensity, and the breaks of the Costa Vicentina are producing conditions that experienced surfers plan their year around. For retreat guests who surf seriously, December on the western Algarve coast is the month.
Christmas week in the Algarve is more animated than the rest of December — the Portuguese families who spend Christmas at coastal properties in the south, the northern European visitors who have discovered the Algarve as a winter sun destination, and the general festive energy of the coastal towns all combine to give the Algarve a Christmas character that is specifically its own. Not the dark and cold of a northern European Christmas, but outdoor dinners, lights on the seafront, and sardines still available at the restaurants that stay open.
For the full Algarve picture, our yoga retreats in the Algarve guide covers the three areas of the region.
Lisbon: The Festive City
Lisbon in December has a quality that summer visitors never see: the city decorated for Christmas, the chestnut sellers on every corner, the Christmas markets in the Praça do Comércio and the Parque Eduardo VII, and the particular warmth of a southern European city that has decided to celebrate the season without the cold that makes the same impulse in northern Europe feel desperate.
The Alfama in December evenings — the lanterns lit, the fado music audible from the restaurants, the viewpoints over the Tagus at their most atmospheric in the low winter light — is one of the great urban experiences Portugal offers at any time of year and specifically worth combining with a retreat week nearby.
Retreat programmes near Lisbon in December — in Sintra, Cascais, or the Arrábida — use the city as a cultural anchor for one evening of the retreat week. The Christmas market at the Praça do Comércio, the Jerónimos Monastery in Belém lit for the season, and the traditional pastéis de nata at Pastéis de Belém (open every day of the year, including Christmas Day) provide the cultural excursion that December Lisbon makes possible.
The Alentejo: Quiet and Honest
The Alentejo in December is the region at its most introspective. The olive harvest is finishing its run, the last of the new oil is being pressed and bottled, and the plains between Évora and Beja have the quality of an agricultural landscape settling into its winter pause. The whitewashed villages are quiet — genuinely, not performatively quiet — and the traditional restaurants serving caldo verde, sopa de pedra, and the slow-cooked pork dishes of the Alentejo winter kitchen are doing their best work of the year.
The Christmas celebrations in the Alentejo are specifically and entirely local: the Consoada (Christmas Eve dinner) is the most important family meal of the year in Portugal, and the traditional Alentejo version — bacalhau cozido (boiled salt cod with potatoes, eggs, and vegetables) at midnight followed by midnight mass — is a cultural experience that requires being in the right place and having the right hosts.
Retreat centres in the Alentejo that stay open through Christmas and create a version of the Consoada tradition for their guests — the bacalhau, the candlelight, the communal table — are offering something genuinely specific to this country and this season.
The Silver Coast: Nazaré and Big Waves
December is the month Nazaré becomes international news. The submarine canyon off Praia do Norte that amplifies Atlantic swells to extraordinary heights is at its December peak, and the big-wave sessions that periodically produce the largest surfed waves in recorded history happen in December more than any other month. The tow-in surfers — Garrett McNamara, Rodrigo Koxa, Sebastian Steudtner — arrive when the forecast shows the conditions, and the clifftop at Praia do Norte fills with spectators watching waves of 20-30 metres break from a respectful distance.
A retreat based near Óbidos or Peniche in December with a day trip to Nazaré during a big swell event — the forecast available 48-72 hours in advance on surf forecasting sites — is one of those specific combinations that requires being in the right part of Portugal at the right time of year. December on the Silver Coast is that time.
Beyond the big waves, Óbidos in December is decorated for its Christmas Village festival — the medieval walled town transformed with Christmas markets, mulled wine, artisan stalls, and the ginja in chocolate cups that is always available but feels more appropriate in December than any other month.
