Weather in Buenos Aires in November

Prime time. November is about as good as Buenos Aires gets. Highs average 23.4 °C, lows 17.2 °C, and rain falls on 8 days — nothing in the month is working against you.

Buenos Aires barely has seasons. November scores 83 out of 100 against a best of 83 in April — a gap small enough that the month you choose matters far less here than the week you choose.

Rain on 8 days, 3 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: it never really gets hot: not one day in an average November reaches 30 °C. Across the twenty years measured, the hottest November day reached 31 °C and the coldest night fell to 8.7 °C, and the wettest single day dropped 69 mm — roughly 69% of the month's rain in one day.

November is moderately variable: 31 mm in the driest year against 206 mm in the wettest, around an average of 100 mm. Roughly two Novembers in three land near that average, and the third does something else entirely.

Wind sits around 17.9 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity is unremarkable at 71%.

How November sits in the year

The month is on the way up: 3.4 °C warmer than October, and December adds another 2.6 °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 Buenos Aires's year: 13.9 hours of daylight, gaining 0.8 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

Despite being inland, the year stays fairly even: 18.9 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, May 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 Buenos Aires versus nearby

If Buenos Aires is one option among several, the nearby comparison is worth making. Rosario is the weaker option in November — 5.7 °C warmer, 1 day more rain. Mar del Plata is close enough to be a coin toss — 3.9 °C cooler, 2 days more rain.

So: November is effectively as good as it gets here — 0 points behind April, which is inside the margin where the weather stops being the deciding factor and price starts being it.
