Best time to visit Aveiro

July is the best month in Aveiro, scoring 97 out of 100, with January the weakest at 54. The 43-point spread means timing is worth planning around without being decisive. The good window runs June to September — 4 months within ten points of the best.

August is the warmest month at 26.8 °C and January the coolest at 13.8 °C — a 13 °C spread across the year.

There is a real wet season here. January, March, April, October, November and December carry the rain — up to 13 wet days in a month — while June to August drop as low as 2. That 11-day gap is the biggest single difference between a good month and a bad one in Aveiro, and it moves further than the temperature does.

The sea peaks at just 18.5 °C, which is wetsuit territory even at its warmest — a coast to look at rather than swim in. Daylight runs from 9.3 hours in winter to 15.1 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are July, August, June. The one to think twice about is January. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
