Weather in Porto Alegre in February

Shoulder season. February sits in between. You will get good days and you will lose some. Highs average 29.8 °C, lows 20 °C, and rain falls on 13 days — nothing in the month is working against you.

February ranks 11 of 12 — near the bottom of Porto Alegre's year. April is the month that works, and the swing between the two is 18 points, which is a different holiday rather than a slightly better one.

Rain on 13 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 29.8 °C days and 20 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 12 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest February day reached 39.4 °C and the coldest night fell to 13 °C, and the wettest single day dropped 54 mm — roughly 52% of the month's rain in one day.

February is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest February on record still delivered 204 mm against 47 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 103 mm average is a reasonable planning figure, not a promise.

Wind is light at 8.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 77%, high enough to notice on the warm days without dominating them.

How February sits in the year

Temperatures hold steady either side: 29.4 °C in January, 29.8 here, 28.5 in March. Nothing about the timing within the month matters much.

Daylight in February

13.2 hours of daylight, losing 0.8 hours across the month. That is between Porto Alegre's extremes of 14.1 and 10.2 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 25.3 °C in February — warm enough to stay in as long as you like. This is the warmest the water gets all year.

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.

February in Porto Alegre versus nearby

If Porto Alegre is one option among several, the nearby comparison is worth making. Curitiba is close enough to be a coin toss — 3.3 °C cooler, 9 days more rain. São Paulo is close enough to be a coin toss — 2.4 °C cooler, 6 days more rain.

So: February works, with April the better month by 16 points if the dates can move. If they cannot, nothing here should stop you booking.
