Official AEMET observations at Adolfo Suárez Madrid-Barajas Airport—the market's resolution source via Wunderground—recorded a maximum temperature of 22.3°C on April 3, 2026, at 18:10 local time, rounding to 22°C under whole-degree criteria and driving trader consensus to 100% implied probability. This outcome reflects accurate pre-event forecasts from AEMET and ECMWF models predicting mild highs amid a stable high-pressure ridge, light northerly winds, and partial cloud cover that capped warming, consistent with early spring climatology where April averages 18-19°C at the site. Nearby stations like Retiro hit 21.4°C, reinforcing uniformity. Realistic challenges include rare data revisions post-finalization or sensor discrepancies, though cross-verified records make shifts improbable as resolution nears.
