Porto

Late spring and early autumn suit sightseeing, though Atlantic rain can still disrupt outdoor plans.

Mild, changeable Atlantic weather calls for layers and a waterproof jacket, especially in winter.

Generally moderate, with accommodation and dining cheaper than Lisbon; save by using cafés and local eateries.

Metro, buses and suburban trains cover most sights, but steep streets and river crossings can slow journeys.

Visit Ribeira, São Bento station, Clérigos Tower, Palácio da Bolsa and Vila Nova de Gaia’s port lodges.

Take normal city precautions, particularly around crowded tourist areas and at night near transport hubs.
