Official observations from Amsterdam Airport Schiphol, the primary resolution source, recorded a daily maximum of 22°C on August 29, 2026, with hourly peaks reaching approximately 22.3°C before afternoon cooling under increasing cloud cover and southwesterly flow. This aligns closely with the 1991–2020 climatological average high of 21.2°C and recent model consensus, eliminating any realistic chance of higher readings. Trader consensus at 100% for the 22°C outcome reflects verified station data rather than forecasts, as post-event revisions within the resolution window remain unlikely given stable observational records.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
