This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Amsterdam Airport Schiphol Station in degrees Celsius on 3 Sep '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=eham If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Latest ensemble forecasts from the Met Office, ECMWF, and GFS models indicate a daytime maximum near 22°C for Amsterdam on September 3 under mostly cloudy conditions with scattered showers and moderate westerly winds. This value sits slightly above the 1991–2020 climatological average high of 20.6°C yet remains tempered by Atlantic maritime air, high humidity near 80%, and precipitation chances of 40–50% that limit surface heating. The near-even market split between 22°C and 23°C reflects small ensemble spread and sensitivity to the precise timing of any brief clearing or heavier rain bands. Official KNMI station readings at the end of the calendar day will determine the outcome.
