Official meteorological observations from Amsterdam Airport Schiphol (EHAM) on October 8, 2026, recorded a minimum air temperature of 11°C, directly supporting the market's 100% implied probability for that outcome. Synoptic conditions featured mild southwesterly flow under partly cloudy skies with dew points near 8°C, preventing further nocturnal cooling below this threshold. Historical climatology for the date shows average lows around 8–9°C, making the observed value mildly above normal yet consistent with the specific atmospheric setup. Trader consensus reflects high confidence in KNMI-verified station data, which resolves such markets. While instrument calibration discrepancies or microscale variations at non-standard sites could theoretically alter readings, official protocols and cross-verification make meaningful shifts improbable.
