Traders have overwhelmingly priced 19°C as the highest temperature in Amsterdam on September 20 at near-certainty due to real-time observations from official Dutch meteorological networks confirming this peak under stable high-pressure conditions. European weather models showed minimal diurnal variation and no late-day warming potential, aligning with typical mid-September climatology where daily maxima average 17–20°C. This market consensus reflects verified station data rather than forecasts alone. The primary uncertainty window has closed as the date advances, though minor revisions could arise from station-specific microclimate differences or final quality-controlled adjustments by monitoring agencies.

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.
