Trader consensus on Polymarket reflects the tight clustering of ECMWF and GFS ensemble forecasts for Madrid's highest temperature on April 5, projecting 24-27°C amid a building high-pressure ridge over Iberia that promises above-seasonal warmth, with early April norms around 17-19°C at Adolfo Suárez Madrid-Barajas Airport. The near-even split among 24°C (25%), 25°C (23.5%), and 26°C (28%) stems from model spread in boundary layer mixing, potential afternoon cloudiness, and steering winds, introducing genuine uncertainty just two days out. Key differentiators include ridge intensification potential versus transient low-level moisture; watch AEMET updates and fresh ensemble runs tomorrow for shifts ahead of resolution based on official airport observations.
