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 14 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.Trader consensus on a 23°C daily maximum for Amsterdam on September 14 reflects consistent observational data and model outputs from agencies such as KNMI and ECMWF, showing a peak under partly cloudy skies with southwesterly flow and minimal diurnal range. Afternoon readings stabilized near this level after a morning start in the mid-teens Celsius, aligning with late-summer climatology for the region where September highs average around 19°C but can reach the low 20s under stable high-pressure influence. Minor forecast spreads across ensembles remain well within the 23°C threshold, with no evidence of stronger advection or clearing that would push temperatures higher. Late-day cooling or station-specific microclimate variations represent the only realistic paths to a different resolution, though current surface observations and pressure trends make such shifts improbable before midnight local time.
