Northern Portugal (Porto, Minho, Douro)
December returns to wintry, damp conditions with chilly, damp days and short daylight in the far north; averages hover around 8-12°C, cooler in high terrain. Occasional storms can bring downpours and strong winds, and while snow is rare below 500-600m it’s possible higher up; holiday markets in Porto and Braga are atmospheric despite the wet. Bring a heavy raincoat, waterproof shoes and warm layers for evening strolls along the Ribeira.

Lisbon & Tagus Valley (Lisbon, Cascais, Sintra, Évora)

Alentejo & Interior South (Évora plains, Alentejo hills)
December is mild to cool with periodic stormy days; nights are chilly but rarely freezing on the plains, while hilltops feel colder. Historic towns take on a quieter winter rhythm and cozy restaurants fill up - great for food-focused travel. Pack layers, a rainproof jacket, and slip-resistant boots for potentially muddy village lanes.
Algarve (Faro, Lagos, Sagres, eastern coast)
December is mild and often pleasantly quiet: daytime highs typically hover around the mid-teens with cooler nights, and festive markets in Faro and small towns add seasonal charm. Storms do occur and can bring heavy rain and surf, particularly on the exposed southwestern headlands. Pack layers, a waterproof, and walking shoes for cliff routes; the region is popular with off-season golfers and birdwatchers.
Madeira (Funchal, levadas, high peaks)
December is mild and festive: Funchal hosts Christmas lights and events while daytime temperatures sit comfortably in the mid-teens. Showers are frequent on the north coast but the island rarely sees cold snaps; mountain tops sometimes get chilly and windy. Pack layered clothing, a waterproof for variable conditions and comfortable shoes for exploring town and coastal promenades.
Azores (São Miguel, Pico, Faial, Flores)
December remains mild compared with continental Europe but unsettled with regular Atlantic storms and blustery days; daytime temperatures usually sit between 13-16°C. Holiday markets and traditional festivities occur in larger towns such as Ponta Delgada. Bring solid rain gear, layered clothing for rapid microclimate changes, and plan for possible ferry or small-plane schedule disruptions.
