Algarve vs Azores

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.

Azores

The Azores have a mild maritime climate with moderate temperatures year-round (14-25°C). Weather is famously changeable — locals say you can experience four seasons in one day. Rain is possible in any month, but summers are significantly drier and warmer.

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.

Azores

A rental car is essential for exploring the islands properly. Public buses exist on São Miguel and Terceira but are limited and infrequent. Inter-island travel is by short domestic flights (SATA) or summer ferries (Atlânticoline). Taxis are available but expensive for touring.

Walkability: Ponta Delgada's historic center is compact and walkable. Beyond towns, a car is necessary. The islands have excellent hiking trail networks (PR trails) but these are recreation, not transportation. Inter-village walking is possible but distances are significant.
