Algarve vs Porto

Algarve

The Algarve has the sunniest climate in continental Europe — 300 days of sunshine annually, warm dry summers, and mild winters. The sea is warm enough for swimming from May through October (17-24°C). The western Algarve around Sagres and Lagos receives more Atlantic wind and cooler temperatures than the sheltered eastern Algarve around Tavira.

Porto

Porto has a Mediterranean-influenced Atlantic climate — warm, dry summers and mild, wet winters. It gets significantly more rain than Lisbon, especially from November to March. Summers are warm and sunny but moderated by Atlantic breezes. The city looks beautiful in every season.

Algarve

A rental car is the most practical way to explore the Algarve — the coast and inland areas are spread over 200km east-to-west, and many of the best beaches and villages are only accessible by car. The IP1/EN125 main coastal road links all major towns. Public buses (Eva Transportes) connect coastal towns adequately, and the Faro-Lagos/Faro-Tavira rail line is useful for town-to-town travel.

Walkability: Individual towns — Lagos Old Town, Tavira, Silves, and central Faro — are pleasant and very walkable on foot. The Fishermen's Trail (Trilho dos Pescadores) is a superb multi-day clifftop walking route from Odeceixe south to Burgau. The coast road is not walkable end-to-end; a car or bus is needed between destinations. Albufeira and Vilamoura resort areas are bikeable but not particularly interesting for walking beyond the beach.

Porto

Porto has a modern metro system, extensive bus network, and iconic historic trams. An Andante card is required for metro and buses — buy it at metro stations (€0.60 for the card plus fares). The city is walkable but extremely hilly, so transit helps with the steeper climbs.

Walkability: Porto is best explored on foot but be prepared for serious hills. The area from Ribeira up to the Se Cathedral involves very steep climbs. Wear comfortable shoes with grip for the cobblestones. The flat areas along the river and in the Boavista district are easy walking.
