Forecast consensus from European and global models, including ECMWF and Met Office runs, centers Amsterdam's August 9 maximum near 28–30 °C under warm-air advection and high pressure, well above the 21–22 °C August climatology. Trader positioning around the 29 °C outcome reflects modest ensemble spread, with differences arising from boundary-layer mixing, afternoon cloud development, and localized sea-breeze effects that can trim peak values by 1–2 °C. Official resolution depends on the precise daily maximum recorded at representative KNMI stations; upcoming 48-hour model updates and any shift in steering flow will determine whether probabilities tilt toward 28 °C or 30 °C.

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 9 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.
