Recent official forecasts from models including ECMWF and GFS, along with KNMI-aligned guidance, indicate a high near 18–19°C for Amsterdam on September 21 under stable high pressure and northwesterly flow. Mostly cloudy skies with light winds and minimal precipitation risk support this range, aligning closely with the 1991–2020 climatological average high of 18.5°C. The market’s strong consensus on 19°C reflects these consistent model outputs and limited day-to-day variability, while the smaller probabilities for 20°C or higher account for possible brief afternoon warming if cloud cover thins more than expected. Updated runs overnight or early on the 21st will provide the final observational tiebreaker 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.
