# Argentina Faces Early Summer Heatwave With Temperatures Nearing 40°C Rising temperatures across northern Patagonia and northern provinces signal an early start to summer. - **Source:** [La Nación](https://www.lanacion.com.ar) - **Published:** 2026-11-09 - **Topic:** [climate](https://brifing.si/c/climate) - **Original article:** - **On Brifing:** https://brifing.si/s/70105849-3693-41be-92a2-4597bacfcfec ## Early Summer Heat Patterns Argentina is experiencing a significant shift in weather conditions starting Monday, November 9. Stable atmospheric conditions across the central regions are facilitating a rapid rise in temperatures. This warming trend serves as an early preview of summer, with some regions expected to reach peak heat levels near 40°C by mid-week. ## Patagonian Warming and Variability The northern Patagonia region is seeing a quick recovery in temperatures, with Neuquén expected to hit maximums between 30°C and 31°C. Meanwhile, Bariloche anticipates reaching 25°C. Conversely, the extreme southern tip of the country faces a different scenario, as an advancing front brings intense winds and rain, contrasting with the northern heat. ## Peak Heat Forecasted Mid-Week The most intense heat is projected to occur between Tuesday, November 10, and Wednesday, November 11. The Alto Valle region could see temperatures near 36°C. Eastern Río Negro and La Pampa are expected to experience even more pronounced warming, with mercury levels potentially climbing toward 39°C during this specific period. ## Northern Provinces Extreme Temperatures The heatwave is expected to intensify as it moves toward northern Argentina. Santiago del Estero is identified as one of the most affected areas, where thermometers could approach 40°C between Wednesday, November 11, and Thursday, November 12. This represents the first major summer-like heat episode for these northern provinces this season. ## Moderate Conditions in Central Areas Central and northeastern regions will experience a slower warming process compared to the north. On Monday, temperatures remain relatively moderate, with maximums around 26°C in Córdoba, 28°C in Mendoza, and 25°C in Corrientes. These areas are currently in a transitional phase before the more significant temperature surge arrives later in the week. ## Precipitation in Northwestern Regions While much of the country enjoys stable, clear weather, the northwest continues to experience variable conditions. Salta and Jujuy may still see scattered showers due to easterly circulation interacting with local topography. Misiones might also record very light, dispersed rainfall, though the general outlook for the central Argentine territory remains dry. ## Meteorological Context and Dynamics The current weather pattern is driven by a combination of stable air masses and specific frontal movements. While a second front advances over the extreme south, it fails to penetrate the northern Patagonian strip, allowing the heat to build. This atmospheric configuration creates a stark divide between the cooling south and warming north. ## Implications of Seasonal Transition This early heatwave highlights the onset of summer characteristics across Argentina. With temperatures climbing steadily through Friday, November 13, residents in affected regions should prepare for sustained high-heat conditions. Monitoring local updates is essential as the transition from spring to summer brings these rapid and intense shifts in regional weather patterns. ## Sources covering this story - https://www.lanacion.com.ar/sociedad/se-viene-un-veranito-en-la-argentina-donde-se-esperan-temperaturas-de-hasta-40c-y-como-seguira-el-nid08112026/ — --- _Summary written by Brifing from the original reporting.
