Trader consensus on Polymarket closely splits between 28°C (41%) and 29°C (31.5%), with 27°C (21%) viable, reflecting genuine uncertainty in the latest GFS and ECMWF forecast ensembles projecting Buenos Aires highs of 27–28°C amid a persistent subtropical ridge promoting subsidence, clear skies, and enhanced solar heating. This setup continues a warmer-than-average early April pattern—historical highs average 23°C—with Servicio Meteorológico Nacional (SMN) guidance at 27°C under partly cloudy conditions and an overnight minimum near record 24.1°C signaling trapped heat. Model spread hinges on afternoon cloud development and boundary layer mixing; intraday observations at Ministro Pistarini International Airport will clarify the peak before evening resolution.
