Porto in June The São João festival, from the night of 23 June into the morning of the 24th, is Porto's biggest street party. People tap each other's heads with small plastic hammers, eat grilled sardines and stay out all night. Rooms book out early. It rarely rains.
June in Porto was on the warm side, averaging 23°C by day and 15°C at night. With about 6 rain days, showers were an occasional nuisance rather than the rule. In 2011, June had no rain day at all; in 2012 it had 11.
Long days, up to 15.1 hours of light, left room for a late stroll after dinner. About 2 days a month still climbed past 30°C, the ones where you looked for shade. The warmest year was 2025, with highs averaging 25.4°C, 2.2°C above normal.
