Trader consensus on Polymarket closely splits between 24°C, 25°C, and 26°C for Buenos Aires' highest temperature on April 17, mirroring the 2-3°C spread in latest Servicio Meteorológico Nacional (SMN) guidance, AccuWeather projections, and global models like GFS and ECMWF, which forecast partly cloudy skies, highs near 24-25°C, and light northerly winds moderating into sea breezes. This tight clustering reflects inherent short-range forecast uncertainty from variable afternoon cloud development, urban heat island amplification at Ministro Pistarini International Airport—the resolution site—and subtle shifts in boundary layer mixing. April 2026 has trended 2°C above the 21°C historical average amid high-pressure dominance, with yesterday's high near 24°C; new SMN updates and hourly observations starting dawn April 17 could tip the balance.
