Weather in Porto Alegre in November

A good month. November works. It is not the peak, but nothing about it fights you. Highs average 26.1 °C, lows 15.6 °C, and rain falls on 11 days — nothing in the month is working against you.

November ranks 4 of 12 in Porto Alegre: past the worst of the year but short of April, which is the month to book if the dates are open.

Rain on 11 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: 4 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest November day reached 35.7 °C and the coldest night fell to 8.6 °C, and the wettest single day dropped 62 mm — roughly 56% of the month's rain in one day.

November is moderately variable: 23 mm in the driest year against 267 mm in the wettest, around an average of 110 mm. Roughly two Novembers in three land near that average, and the third does something else entirely.

Wind is light at 9.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 80%, high enough to notice on the warm days without dominating them.

How November sits in the year

The month is on the way up: 1.9 °C warmer than October, and December adds another 2.1 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in November

November is at or near the longest days of Porto Alegre's year: 13.6 hours of daylight, gaining 0.7 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 20.9 °C in November — swimmable, but it takes a moment to commit. The sea peaks at 25.3 °C in February and bottoms out at 16.5 °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

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, September is the trade worth considering — 6 points weaker on weather, and materially quieter.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

November in Porto Alegre versus nearby

If Porto Alegre is one option among several, the nearby comparison is worth making. Curitiba is the weaker option in November — within a degree on temperature, 8 days more rain. São Paulo is the weaker option in November — within a degree on temperature, 7 days more rain.

So: November is effectively as good as it gets here — 1 points behind April, which is inside the margin where the weather stops being the deciding factor and price starts being it.
