Trader consensus on Polymarket tightly clusters around 20–22°C for Buenos Aires' highest temperature on May 4, mirroring the spread in latest short-range forecasts from GFS and ECMWF models, which project daytime peaks in this range amid light southerly winds and partial cloud cover. This positioning stems from the Servicio Meteorológico Nacional's (SMN) recent trimestral outlook confirming above-normal temperatures for May 2026, following a warm May 1 high near 24°C and a brief cooldown over May 2–3. Differentiating factors include boundary layer mixing efficiency, potential afternoon cumulus development suppressing peaks, and urban heat island effects at official stations like Aeroparque. New model runs every 12 hours and SMN updates could refine probabilities ahead of resolution.
