Uruguay Climate – June 2026 Update
Top 5 Cities: Montevideo, Salto, Paysandú, Las Piedras, and Rivera
This month in numbers
Uruguay experienced a notably cold June, with the average temperature of 9.38°C ranking as the 81st coldest June in 86 years of records, an anomaly of -2°C compared to the 1961–1990 baseline. The three-month period from April to June 2026 also saw cooler-than-average conditions, with a mean temperature of 13.82°C, ranking 65th coldest on record. In stark contrast, the global land temperature for June 2026 was the 3rd warmest on record, at 16.46°C, an anomaly of +1°C.
What changed
Uruguay's recent cooler trend stands out against a backdrop of global warming. While the country recorded a significantly colder June and a cooler April-June season, the global land temperature for both periods ranked among the warmest on record. Uruguay was the coolest country globally for the latest month's anomaly, at -2.00°C, and also ranked as the 233rd coolest out of 234 regions for the three-month anomaly. This cooler pattern for Uruguay follows a warmer start to the year, with February and March both experiencing above-average temperatures.
What’s driving change?
The current cooler conditions in Uruguay are occurring amidst a weak El Niño event, which is expected to strengthen and persist through the end of 2026. El Niño typically brings wetter conditions to Uruguay during spring and summer, with no clear temperature signal for the region. However, a strong polar air mass swept across southern South America between late June and early July, bringing record low temperatures to Uruguay, Argentina, and Chile. This cold spell prompted a nationwide red alert in Uruguay due to the severity of the cold.

Shifting Seasons
Warm / cold seasonsKöppen Cfa · TemperateHow spring and autumn have shifted in Uruguay. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (17.3°C, from 1940–1969); autumn is the date they fall back below it. Temperature swings 12.2°C peak-to-peak across the year - a classic four-seasons rhythm.

FAQs
FAQs
How is the climate in Uruguay changing?
Uruguay 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 Uruguay come from?
Climate data for Uruguay 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.
