Weather in Aveiro in November
Portugal · 20-year averages, November
A good month. November works. It is not the peak, but nothing about it fights you. Highs average 16.9 °C, lows 10.4 °C, and rain falls on 13 days — nothing in the month is working against you.
November ranks 9 of 12 in Aveiro: past the worst of the year but short of July, which is the month to book if the dates are open.
Rain on 13 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 16.9 °C days and 10.4 °C nights; the spread matters more here than any single number.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest November day reached 25 °C and the coldest night fell to 3.4 °C, and the wettest single day dropped 61 mm — roughly 46% of the month's rain in one day.
November is moderately variable: 6 mm in the driest year against 239 mm in the wettest, around an average of 132 mm. Roughly two Novembers in three land near that average, and the third does something else entirely.
Wind is light at 6.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, high enough to notice on the warm days without dominating them.
How November sits in the year
The month is on the way down: 5 °C cooler than October, with December dropping another 2.4 °C. The first week and the last are not the same trip.
Daylight in November
10 hours of daylight, losing 1 hours across the month. That is between Aveiro's extremes of 15.1 and 9.3 hours, so days are long enough not to constrain the plan.
Sea temperature
The sea sits at about 16.7 °C in November — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. The sea peaks at 18.5 °C in August and bottoms out at 13.7 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.
How busy it gets
Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
November in Aveiro versus nearby
If Aveiro is one option among several, the nearby comparison is worth making. Leiria is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Braga is close enough to be a coin toss — within a degree on temperature, 1 day more rain.
So: November is a compromise. July is 33 points better and is what Aveiro is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
