Official KNMI observations at Amsterdam Airport Schiphol station—the market's resolution authority—recorded a maximum temperature of 16°C on May 10, 2026, driving trader consensus to 100% implied probability for this outcome amid heavily overcast skies and northerly winds that suppressed solar heating and advection of warmer air. This aligns with pre-event ECMWF and GFS model runs forecasting mid-teens highs under persistent low cloud cover, matching early May climatological averages of around 16°C for the region. While resolved with high certainty via automated sensor data and quality-controlled measurements, realistic challenges include rare post-processing revisions for instrument anomalies or microsite discrepancies, though historical precedents show such adjustments affect less than 0.1% of daily records. Traders await no further updates as the market nears final settlement.
