Argentina Climate – June 2026 Update
Top 5 Cities: Buenos Aires, Córdoba, Rosario, Mendoza, and La Plata
This month in numbers
Argentina experienced a cooler-than-average June 2026, with temperatures reaching 7.11°C, an anomaly of -0.5°C compared to the 1961–1990 baseline. This ranked as the 65th coolest June in 86 years of records. In contrast, the global land temperature for June 2026 was significantly warmer, ranking as the 3rd warmest on record with an anomaly of +1°C.
What changed
Looking at the broader picture for April–June 2026, Argentina's average temperature was 11.06°C, a slight increase of +0.1°C above the 1961–1990 baseline, ranking 42nd warmest in 86 years. This places Argentina as the 229th coolest out of 234 regions globally for this three-month period. This regional cooling trend stands in stark contrast to the global land temperature, which saw its 2nd warmest April–June on record, with an anomaly of +1°C.
What’s driving change?
A significant driver of Argentina's cooler June was an intense Antarctic air mass that swept across the country from early June 2026, bringing snow, strong winds, and unusually low temperatures to over ten provinces, including rare snowfall in coastal areas of Buenos Aires province. This "Antarctic bomb," as it was popularly dubbed, led to temperatures as low as -14°C in Jujuy. This cold snap occurred even as a weak El Niño is currently established in the equatorial Pacific, with a 100% probability of persisting through the end of 2026 and into early 2027. While El Niño typically brings warmer and wetter conditions to northern Argentina, the immediate impact of the polar air mass temporarily overrode this influence.

Looking ahead
El Niño is expected to strengthen into a very strong event by the Northern Hemisphere winter of 2026-2027, with a 63% probability of exceeding +2.0°C in the Niño 3.4 region, which could bring wetter-than-average conditions and flood risk to the La Plata Basin, including northern Argentina, in the coming months.

Shifting Seasons
Warm / cold seasonsKöppen Cfb · TemperateHow spring and autumn have shifted in Argentina. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (14.2°C, from 1940–1969); autumn is the date they fall back below it. Temperature swings 13.4°C peak-to-peak across the year - a classic four-seasons rhythm.

FAQs
FAQs
How is the climate in Argentina changing?
Argentina is warming in line with the rest of the world. The page above shows the latest monthly temperature anomaly versus the 1961-1990 baseline, the long-term annual trend, and the region's rank in the historical record. The headline panel also shows the long-term trend rate per decade and the warmest and coolest years on file.
Where does the climate data for Argentina come from?
Climate data for Argentina comes from Our World in Data, sourcing Copernicus ERA5 and HadCRUT5 (national temperature anomaly) and the Global Carbon Project via Our World in Data (CO₂ emissions), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.
Which areas does the Argentina climate data cover?

How often is the Argentina climate update refreshed?
The Argentina climate update is refreshed monthly, typically a few days after the previous month closes and the upstream provider (Met Office HadUK-Grid, NOAA Climate at a Glance, Copernicus ERA5 or the Global Carbon Project) publishes its update. See the Climate Rankings for cross-region comparisons.
