Forecast consensus from multiple models positions a maximum of 19°C as the most probable outcome for Amsterdam on September 21, aligning with the market's 52.5% implied probability on that threshold. A building high-pressure ridge over the North Sea has promoted mostly cloudy skies with light westerly to northwesterly flow and minimal cloud disruption, keeping daytime heating near the 1991–2020 climatological average high of 18.5°C. Recent runs show little spread in maximum temperatures, with limited potential for either stronger subsidence warming toward 20°C or greater cloud cover and advection pulling values to 18°C or below. Traders appear to weigh the stability of these short-range forecasts against typical model uncertainty in boundary-layer conditions two days out.

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.
