Weather in Córdoba in December
Argentina · 20-year averages, December
Shoulder season. December is shoulder season in Córdoba — cheaper, quieter, and a genuine gamble. Highs average 32.6 °C, lows 16.8 °C, and rain falls on 12 days — nothing in the month is working against you.
December ranks 11 of 12 — near the bottom of Córdoba's year. June is the month that works, and the swing between the two is 50 points, which is a different holiday rather than a slightly better one.
Rain on 12 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 32.6 °C days and 16.8 °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: 9 days clear 35 °C, so a serious heatwave is normal rather than notable; the day swings 15.7 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest December day reached 42.3 °C and the coldest night fell to 7.8 °C, and the wettest single day dropped 105 mm — roughly 91% of the month's rain in one day.
December is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest December on record still delivered 270 mm against 46 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 115 mm average is a reasonable planning figure, not a promise.
Wind is light at 1.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 58%.
How December sits in the year
Temperatures hold steady either side: 31 °C in November, 32.6 here, 33 in January. Nothing about the timing within the month matters much.
Daylight in December
December is at or near the longest days of Córdoba's year: 14.2 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.
An inland climate
With no coast nearby, the year swings a fair way — 27.5 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. Within December itself the daily swing is 15.7 °C, so mornings and afternoons need different clothes.
How busy it gets
Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
December in Córdoba versus nearby
If Córdoba is one option among several, the nearby comparison is worth making. Rosario is close enough to be a coin toss — within a degree on temperature, 1 day less rain. San Miguel de Tucumán is close enough to be a coin toss — within a degree on temperature, 1 day more rain.
So: December is a compromise. June is 48 points better and is what Córdoba is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
