**Current forecasts from official and major meteorological sources indicate a daily maximum of 12–13°C for Buenos Aires on August 23, 2026, aligning closely with the market’s leading implied probabilities (13°C at 44.5%, 12°C at 32%).** In the Southern Hemisphere winter, high pressure and light southeast-to-east winds are promoting gradual daytime warming under partly cloudy skies with no precipitation expected, limiting strong warm-air advection. Numerical models and the Servicio Meteorológico Nacional project a high near 13°C, while other global guidance (including Met Office and ensemble runs) centers on 12°C, reflecting typical mid-August variability where daily maxima rarely exceed the 11–14°C envelope. Climatologically, the date averages around 16°C, but the current stable, cooler pattern—following recent modest cooling—has tightened expectations toward the lower end of the historical range. Traders appear to weight the consensus official forecast and model agreement most heavily, with limited upside risk from unexpected warming given the steering flow and lack of incoming disturbances. Updated model runs and any late adjustments to boundary-layer mixing or cloud cover remain the key near-term variables that could shift resolution odds.
