Porto
A wet winter is the price of an empty Ribeira — and September is drier than June.
When to visit Porto
Porto is calmest in January and busiest in August. For the best balance of decent weather and smaller crowds, aim for February.
Porto is wetter than its reputation suggests and that is the central fact of its calendar. The Atlantic brings twelve to fourteen rain days a month from October through April, and around 1,200 mm a year — roughly double Lisbon. What it does not bring is cold: daytime highs sit at 14–15°C through the winter, so the off-season here is damp rather than harsh, and a good raincoat converts January into a perfectly workable month with no queues at all.
Summer is the peak and it is a comfortable one. July and August average 25°C, the Douro valley an hour inland is far hotter, and the city fills with a mix of overseas visitors, Portuguese emigrants home for the holidays, and river-cruise passengers heading upstream to Pinhão. The single busiest night of the year is 23 June, when São João turns the whole city into an all-night street party of grilled sardines, plastic hammers and midnight fireworks over the Douro — it is worth planning a trip around, and worth avoiding if crowds are the thing you dislike.
September is the best month overall: it is warmer than June, considerably drier than either May or October, the Douro harvest is starting, and numbers drop noticeably after the first week. May is the spring equivalent, though it carries more rain. Whenever you go, remember the geography — the old town is built on a gorge, and everything you want to see involves either a steep climb or the Dom Luís I bridge.

Local timing tips
- The Livraria Lello charges a voucher fee that is redeemable against a book, and it is calmest in the first hour — book the slot online rather than queueing.
- Cross the Dom Luís I bridge on the upper deck for the view and take the lower deck back; the Gaia funicular saves the worst of the climb.
- Port lodge tours in Gaia get booked out on cruise days, so reserve ahead and pick one of the smaller houses rather than the ones nearest the waterfront.
- A Douro valley day is best done by train to Pinhão rather than by car — the last hour of the line runs along the river and there is nowhere to park at the quintas.
