Official KNMI observations from Schiphol Airport station—the authoritative reference for Amsterdam weather—confirm the highest temperature on May 11, 2026, reached 11°C amid a cool, unsettled day featuring light showers, northwest winds at force 5, and partial cloud cover that limited solar heating. Preliminary hourly data released overnight, showing a midday peak at 11°C before dropping to 6.9°C by evening, drove trader consensus to near-certainty, aligning with pre-event forecasts of maximums around 11°C under a low-pressure system and polar air advection. While urban heat islands in central Amsterdam could theoretically register 1°C higher, historical precedents and resolution criteria favor Schiphol's verified measurements; only a rare data correction from KNMI would challenge this positioning. Final daily summaries expected today reinforce the market-implied outcome.
