Thời tiết Aveiro, Bồ Đào Nha vào tháng 6

June here is the month the board discusses one date. Sao Joao runs through the night of the 23rd into the 24th: the hotels sell out, the streets stay full until dawn, and the customs are specific - sardines and caldo verde eaten outdoors, paper balloons sent up over the city, fireworks by the river at midnight, and everybody hitting everybody else with squeaky plastic hammers, which is affection rather than assault. Their weather summary, about 23C by day and 14C at night, is almost exactly our row at 22.3C over 14.3C, so this is a mild month rather than a hot one - 55.7mm of rain across 8.4 days, a steady 16.8 kph off the Atlantic, and a sea still at 18.3C. The record: humidity 79 percent, 12.7 hours of sun and AQI 47.

Portugal forum posters describe November as a genuine lottery further north - you could get two weeks of steady rain or two weeks of mild, sunny days with cool evenings, and Aveiro's stretch of coast is squarely in the wetter, windier half of the country compared to the Algarve. When the sun does break through, daytime temperatures in the mid-to-high teens C feel pleasant for walking the canals, but forum regulars all say to pack a proper rain layer and expect a blustery day at some point - November is one of the wetter months here.

Forum posters describe May as bringing genuinely great weather for touring Aveiro's canals by traditional moliceiro boat - the roughly 45-minute round-trip cruise (about 13 euros) through the colorfully painted boats' historic waterways is repeatedly named the top thing to do in town, and posters specifically note it's best enjoyed on a nice-weather day rather than a rainy one. Portugal's broader spring pattern applies here too - generally mild and pleasant but with real day-to-day variability, so a layer for cooler mornings or an unexpected shower is sensible even during a generally good May stretch. Beyond the canal cruise, posters describe Aveiro as a compact, easily walkable town - often visited as a day trip from Porto - that pairs well with a relaxed, unhurried pace.
