Istanbul vs Porto

Istanbul

Istanbul has a transitional climate between Mediterranean and oceanic, with hot summers and cool, rainy winters. The Bosphorus creates microclimates — the Asian side tends to be slightly warmer than the European side.

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.

Istanbul

Istanbul has an expanding metro, tram, funicular, and ferry network all accessible with the Istanbulkart rechargeable transit card. Get one immediately at any metro station or kiosk — single tickets are expensive. Traffic is notoriously bad, so use rail and ferries whenever possible.

Walkability: The historic peninsula (Sultanahmet, Eminonu, Bazaar Quarter) is very walkable but hilly. The Beyoglu/Galata area involves steep hills and stairs. The Asian side neighborhoods of Kadikoy and Moda are flat and pleasant on foot. Traffic and wide highways make some areas pedestrian-unfriendly.

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.
