Trader consensus on Polymarket reflects the latest ECMWF and GFS ensemble runs projecting peak daytime highs near 29°C for Buenos Aires on March 29, amid a subtropical high-pressure ridge promoting sunny skies and efficient diurnal heating after recent humid conditions. The narrow lead for 29°C (23.5%) over 30°C (22.5%) stems from model spread, with some members favoring slight overperformance due to light winds minimizing sea-breeze moderation, while others account for possible afternoon clouds capping at 28°C. Servicio Meteorológico Nacional guidance supports upper-20s Celsius, consistent with March climatology (averages ~25°C) but elevated by ongoing warm anomalies; final hourly observations from Aeroparque station will resolve amid inherent short-range forecast uncertainty.
