Recent forecasts from the Servicio Meteorológico Nacional and major models such as ECMWF and GFS indicate a daytime maximum of 11–13°C in Buenos Aires on August 23, driven by persistent southerly flow advecting a cooler polar air mass behind a Patagonian cold front. This late-winter setup suppresses typical seasonal warming, with light winds and partly cloudy skies limiting daytime heating below the August average high near 16–17°C. Market-implied odds heavily weighting 13°C at 57.5% and 12°C at 26.5% reflect this model consensus and historical analogs of similar frontal passages, while lower-probability outcomes above 14°C would require unexpected rapid warming or model errors. Official observations through the day will determine the exact recorded high for resolution.
