Choose the indoor priority
Pick a museum, collection or other interior you would enjoy even in sunshine. Check its current opening and booking arrangements so the wet-day plan has a real destination rather than several unconfirmed possibilities.
Choose Palácio da Bolsa for a historic interior, or Serralves for contemporary art, checking available admission and visit arrangements first. They are different outings: Serralves needs a journey away from the historic centre, so it is not a quick shelter beside Ribeira.
Dress for repeated transitions
Wear a removable sweater beneath a waterproof jacket and choose shoes that remain comfortable when streets are damp. Leave space to put the outer layer away indoors without spreading wet clothing across your belongings.
Shorten the outdoor connections
Group stops into one part of the city and consider transport for a longer link. Rain can make the slopes tiring or slippery, so a compact route often feels better than trying to preserve every outdoor stop.
For a central plan, combine an available Palácio da Bolsa or Church of São Francisco visit with a meal and a short Ribeira look when the rain eases. São Bento's tile hall can be a brief stop, but keep it clear for travellers rather than using it as somewhere to spend the whole afternoon.
Leave the bridge for better conditions
Avoid making an exposed crossing the essential part of the day when wind or persistent rain makes it unpleasant. Keep a riverside or bridge view as an optional pause you can add if conditions improve.
Give the evening a simple finish
Choose a meal or final stop with an easy route back to your accommodation. A day of carrying damp layers can be tiring even with fewer walking miles, so leave the last connection uncomplicated.
If conditions improve, take a short Rua das Flores walk or return to the riverfront. Save the upper bridge crossing and exposed viewpoints for a suitable window; a rainy-day plan can end with dinner without needing an outdoor finale.
Check before you go
Opening arrangements and visitor rules can change. Check the official information before your trip.
