Forecast models from sources like the German Weather Service and GFS consensus point to a daytime high near 20°C in Munich on September 17 under partly cloudy skies, light westerly winds, and minimal daytime precipitation, aligning with the market's strong weighting toward 20–21°C outcomes. These conditions follow overnight clearing after September 16 thunderstorms, with stable high pressure and moderate humidity supporting typical mid-September values close to the 19.5°C climatological average high. Recent model runs show limited spread, though any unexpected afternoon clearing or residual moisture could nudge readings slightly higher or lower. Traders appear to price in this consensus while acknowledging the narrow uncertainty band around the most probable range.

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=eddm
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.
