San Sebastián vs Thessaloniki

San Sebastián

San Sebastián has an oceanic climate — milder and wetter than the Mediterranean coast. Summers are warm but rarely scorching, winters are cool but mild. Rain is frequent year-round, especially in autumn and spring. The Basque coast is greener than southern Spain for a reason.

Thessaloniki

Thessaloniki has a transitional Mediterranean climate — hotter summers than Western Europe and cooler winters than southern Greece. The city is humid in summer.

San Sebastián

San Sebastián is wonderfully compact and best explored on foot. The entire city from Monte Igueldo to Zurriola beach is walkable within 40 minutes. Local buses cover the wider metropolitan area, and the historic funicular climbs Monte Igueldo.

Walkability: San Sebastián is one of Spain's most walkable cities. The entire center — from the old town to Gros, La Concha to Monte Urgull — is flat and pedestrian-friendly. The elegant waterfront promenade is a joy to walk day or night. Only Monte Igueldo requires a climb (or funicular).

Thessaloniki

Thessaloniki relies on buses as its main public transport — the long-awaited metro is still under construction. The city center is very walkable and taxis are affordable.

Walkability: Excellent in the flat center and along the waterfront. Ano Poli (upper town) requires climbing steep streets but is rewarding. The city is compact enough that most sights are accessible on foot.
