Local context
What to expect in October
🎯 Shoulder season — good value with reasonable accommodation prices Autumn in Porto is often underrated: 20°C, golden light and declining crowds. An interesting window. Expect rain on 40% of days — a light raincoat in the bag is recommended. Not the best window, but acceptable if dates are constrained. August (8.9/10) is significantly better if possible.
