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 22 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.
Latest numerical weather prediction models, including ECMWF runs, indicate a maximum temperature near 19°C in Amsterdam on August 22 due to prevailing Atlantic maritime air masses, moderate westerly flow, and increased cloud cover that limits daytime insolation. This aligns closely with KNMI guidance and places the outcome well within typical late-August climatology for the region, where daily highs average 21–22°C but often trend cooler under such synoptic patterns. Trader sentiment, reflected in the 56.5% implied probability for 19°C and 22.5% for 20°C, shows strong consensus around these values with minimal support for extremes above 21°C or below 18°C. Any last-minute shifts in the 00Z or 12Z model cycles, or unexpected clearing, could influence final resolution.
