The best time to visit Porto is late spring (May and June) and early autumn (September), when the weather is mild and pleasant, the light is gorgeous along the Ribeira and the Douro, and the crowds are thinner than in high summer. July and August are the peak season, with the hottest weather and the busiest streets and riverfront. Winter is the quiet low season, cooler and often rainy but atmospheric and uncrowded.

When to go, and what to expect
Spring (Mar–May)
An excellent time to visit — green landscapes, comfortable walking weather and fewer tourists than summer.
Summer (Jun–Aug)
Great for sunshine and festivals, but expect crowds and the highest demand — book ahead.
Autumn (Sep–Nov)
Ideal early autumn — warm days, harvest season in the Douro and a more relaxed pace.
Winter (Dec–Feb)
Best for budget-minded travellers and those who want the city to themselves, if you don't mind rain.
