Official hourly observations from the KNMI-operated weather station at Amsterdam Airport Schiphol, the market's resolution source, confirm a maximum temperature of 13°C reached midday on May 14, 2026, amid persistent cloud cover, light northerly winds, and a cool air mass over northwest Europe. Evening readings have since dropped to around 6°C with no solar heating left after sunset near 21:30 local time, solidifying trader consensus at 100% implied probability for 13°C. ECMWF and HIRLAM model runs from the past 48 hours accurately forecasted these subdued highs below 14°C, aligning with climatological May variability but cooler than the 16°C monthly average. Only an unlikely post-day data revision by KNMI—such as a corrected sensor reading—could challenge this positioning, with final daily maxima expected imminently.
