Trader consensus on Polymarket reflects substantial uncertainty in five-day forecasts for Madrid's highest temperature on April 4, with implied probabilities spread across outcomes due to ensemble spreads in ECMWF and GFS models showing potential highs from 17°C to 27°C+. AEMET's latest outlook for the early April Holy Week period highlights fluctuating temperatures and high predictive uncertainty, driven by variable upper-air patterns that could steer a warm Azores High ridge southward for advection of subtropical air—favoring 24–27°C+—or allow Atlantic fronts to bring cooler, cloudy conditions below 20°C. Climatological April 4 averages hover near 18°C per historical AEMET data, but spring transitional dynamics amplify day-to-day variability. Watch daily model updates from AEMET and ECMWF for resolution shifts ahead of the event.
