This month in numbers
Argentina experienced a cooler April, with the average temperature at 13.9°C, marking an anomaly of -0.4°C compared to the 1961–1990 baseline. This ranked as the 64th coolest April in 86 years of records. Globally, April 2026 was the 2nd warmest April on record for land temperatures, with an anomaly of +1.1°C. Looking at the three-month period from February to April 2026, Argentina recorded an average temperature of 18.48°C, which is +1°C above the baseline, ranking as the 7th warmest such period on record.
What changed
While April saw a slight cooling trend for Argentina, the broader seasonal picture for February–April 2026 indicates a significantly warmer period, ranking 7th warmest in 86 years. This contrasts with the global land temperature for the same three-month period, which was the 2nd warmest on record, highlighting a widespread warming trend. Argentina's April temperature anomaly placed it as the 4th coolest globally for the month, sitting at 231st out of 234 regions.
What’s driving change?
The shift towards warmer conditions over the past three months in Argentina is occurring as the region transitions from neutral ENSO conditions towards an El Niño event. The NOAA CPC forecast indicates an 82% probability of El Niño developing in May-July 2026, with probabilities rising to 98% by August-October 2026. El Niño typically brings wetter conditions to southern Brazil, Uruguay, and northern Argentina during spring and summer, with an increased risk of flooding. Argentina is currently experiencing a drought that began in June 2023, and this event represents 100% of the drought events logged for Argentina over the past 12 months, an unusual concentration. Between April 17-20, 2026, Argentina also experienced a wave of severe storms, bringing giant hail, intense rainfall, and flash floods to multiple regions, including Villa Mercedes, Villa Carlos Paz, and areas in Chaco and Mendoza. More information on extreme weather can be found at Extreme Weather tracker.
Looking ahead
The strengthening El Niño event is expected to bring excessive rainfall to Argentina's agricultural hubs and prolonged heatwaves beginning in late 2026, with moisture signals consolidating in northeastern Argentina by spring 2026.

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 trend rate is shown as °C per decade in the headline panel; you can also see 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.

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.
