In Paraguay, the thermometer surged to an astonishing +41.5°C at Base Jara, an unprecedented temperature for wintertime in the Southern Hemisphere. To see values exceeding 42°C in the heart of the cold season is nothing short of historic.
Across the region, the heat was widespread and relentless:
- Bolivia recorded 40.0°C in Roboré, after an overnight minimum of 27.6°C — a new winter record smashed.
- Brazil joined the inferno with 40.0°C in Cuiabá, deep in the tropics.
- Even Colombia, on the Northern Hemisphere side, surpassed 41°C, adding to the continental scale of the extreme.
This South American Winter Heat Wave is without precedent — not just a warm spell, but a climatic shock. Such anomalous heat, rivaling midsummer levels, raises alarms about the fragility of seasonal climate norms in the age of intensifying global warming.
For many regions, winter 2025 will be remembered as the year when summer invaded July–August skies, obliterating all notions of seasonal stability.
