Trader consensus on Polymarket heavily favors 18°C (45.5% implied probability) as the highest temperature at Ministro Pistarini International Airport in Buenos Aires on May 3, driven by the latest forecast consensus from the Servicio Meteorológico Nacional (SMN) and global models like ECMWF and GFS, projecting a daytime peak near 18°C amid scattered clouds and cool southerly winds. This positioning reflects a recent cool air mass advection following milder conditions earlier in the week, with May 2 highs also around 18°C, aligning with autumnal climatology where average May maxima hover at 17–19°C. Near-even splits for 17°C (18.5%) and 19°C (25%) underscore short-term forecast uncertainty from potential cloud cover variations or model run updates expected overnight, as inherent in numerical weather prediction.
