Current numerical weather prediction models, including outputs from the German Weather Service (DWD), indicate a maximum near 18–19°C in Munich on September 23 under clear skies, light northeasterly winds, and negligible precipitation risk. This setup favors stable daytime warming without significant cloud interference or frontal systems. Ensemble consensus aligns closely with late-September climatological norms around 18–19°C, while minor differences in boundary-layer mixing and exact timing of peak insolation explain the tight split in market-implied odds between 18°C and 19°C. Final official observations tomorrow afternoon will resolve the outcome.

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.
