Current forecasts from multiple meteorological sources, including GFS model outputs and observations from Schiphol and nearby stations, indicate a daytime maximum near 20–21 °C under persistent cloud cover, light rain or drizzle, and moderate southwesterly flow. This pattern reflects typical late-August Atlantic maritime influence that suppresses diurnal warming, consistent with the 1991–2020 climatological average high of 21.1 °C and recent days’ readings that have remained in the upper teens to low 20s. Trader consensus at 99.5 % for 21 °C therefore reflects the tight clustering of model guidance and surface data rather than any anomalous heat. A realistic challenge would require unexpected clearing that allows greater insolation or a shift in steering flow delivering warmer continental air, either of which could lift the peak by 1–2 °C before sunset.

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 30 Aug '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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.Current forecasts from multiple meteorological sources, including GFS model outputs and observations from Schiphol and nearby stations, indicate a daytime maximum near 20–21 °C under persistent cloud cover, light rain or drizzle, and moderate southwesterly flow.
