Forecast models from sources including the German Weather Service and global ensembles indicate a daytime high of 19–20 °C in Munich on September 17, 2026, consistent with the seasonal average of 19.5 °C and current observations showing afternoon readings near 19 °C under partly cloudy skies with light westerly winds. This alignment of verified measurements and short-range consensus forecasts underpins the market’s near-certain pricing at 20 °C. A modest shift in cloud cover, a later clearing that allows additional solar heating, or a revised observational peak could still produce a 21 °C reading, though such adjustments appear unlikely given the stable synoptic pattern and proximity to 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=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.
