Trader consensus on Polymarket heavily favors a Buenos Aires high of 24°C (37.5% implied probability) for March 23, driven by the latest Servicio Meteorológico Nacional (SMN) forecasts and ensemble model outputs from GFS and ECMWF, which project daytime peaks in the 23-25°C range amid a stable high-pressure system suppressing heat. Recent observations show March 22 highs around 23°C with light southerly winds enhancing coastal cooling, aligning historical late-summer baselines where March averages 24-26°C but current synoptic patterns—low humidity and clear skies—cap extremes below 27°C (2.8%). Upcoming SMN updates at 18:00 local time could shift odds if convective activity emerges, though low probabilities for 19°C or below (2.9%) reflect minimal cold front risk per satellite data.
