Trader consensus on Polymarket reflects tight uncertainty in short-range forecasts for Madrid's highest temperature on April 3, with implied probabilities clustered around 19–20°C amid AEMET's latest prediction of a 21°C maximum under clear skies, northerly winds at 25 km/h, and 0% precipitation chance. This mild outlook stems from a high-pressure ridge stabilizing over Iberia following recent model updates, though ensemble spreads from ECMWF and GFS show variability of 16–24°C due to potential low cloud intrusion or wind shifts affecting diurnal heating. Early April climatology averages 17–18°C highs at Madrid's Retiro station, with spring 2026 seasonal outlooks signaling above-normal temperatures; daily model refreshes through April 2 will clarify steering patterns and refine trader positioning ahead of official measurement resolution.
