Current forecasts indicate overnight lows in Buenos Aires on August 24 will likely fall in the 4–7°C range amid a lingering polar air mass advecting cooler, drier southerly flow, which enhances nocturnal radiative cooling under partly clear skies and light winds. Recent minima near 4–6°C reflect an ongoing cool anomaly below the seasonal average of about 8°C, with model guidance showing potential for further drops if cloud cover decreases or stabilization if winds strengthen or humidity rises. The closely matched market-implied odds across 0–8°C bins capture this short-term uncertainty in exact steering patterns, boundary layer conditions, and Servicio Meteorológico Nacional observations, underscoring how small shifts in these variables can alter the recorded minimum.
