Trader consensus on Polymarket reflects tight uncertainty in ensemble forecasts from GFS and ECMWF models, which project Buenos Aires' highest temperature at Ezeiza Airport on April 4 around 21-22°C amid early autumn mildness, with spreads of 1-2°C explaining closely matched odds for 20°C (23%), 21°C (21.5%), and 22°C (16.5%). Current mild conditions near 20°C today, combined with partly cloudy skies and light winds, support this clustering, but differentiating factors include variable cloud cover impacting solar insolation and potential sea breeze moderation from the Río de la Plata. Servicio Meteorológico Nacional updates and fresh 00Z model runs tomorrow could refine trajectories, as short-range forecasts often shift with evolving upper-air patterns. Historical April maxima at Ezeiza average 22°C, aligning with market-implied odds.
