Trader consensus at 100% for a 26°C high in Amsterdam on September 7 reflects convergent observational data and model outputs showing daytime temperatures peaking near that level under partly cloudy skies with moderate southwesterly flow. Official monitoring at Schiphol and nearby stations, combined with short-range forecasts from agencies like KNMI, indicate afternoon maxima around 25–27°C amid stable pressure and limited cloud cover, aligning closely with historical late-summer patterns where September 7 averages near 20°C but recent warm anomalies support elevated readings. Minor model spread or station-specific microclimate effects could shift the final recorded maximum by 1°C, though current conditions make deviations beyond this range unlikely before resolution.

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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
