This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section. This market will resolve to the temperature range that contains the highest temperature recorded at the Amsterdam Airport Schiphol Station in degrees Celsius on 21 Aug '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Amsterdam Airport Schiphol Station, available here: https://www.wunderground.com/history/daily/nl/schiphol/EHAM. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve until the first data point for the following date has been published on the resolution source. 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.
Recent model consensus from ECMWF and GFS runs positions Amsterdam’s August 21 high temperature near 19–20 °C, aligning with the market’s leading outcomes at 47.5 % for 20 °C and 25.5 % for 21 °C. Northwest flow behind a departing front advects cooler maritime air while scattered showers and increasing cloud cover limit daytime heating. Official guidance from KNMI-aligned sources and Met Office projections show afternoon maxima around 19–20 °C under partly cloudy skies with light-to-moderate northwest winds. This setup follows mid-August warmth that peaked above 30 °C earlier in the month, but recent stabilization and precipitation have anchored the near-term forecast. Updated model runs overnight will refine confidence ahead of market resolution.
