**Forecast models from sources like the GFS and Met Office indicate a daily maximum near 17°C in Munich on September 21, 2026, under stable high-pressure conditions with northwest winds and increasing cloud cover that limits daytime heating.** Partly cloudy skies and light winds are expected to keep temperatures from exceeding this range, consistent with recent observations showing cooler-than-average late-September conditions. Historical averages for the date hover near 19°C, but current atmospheric patterns favor a slightly suppressed peak. Trader consensus, reflected in the 58% implied probability for 17°C and 32.5% for 18°C, aligns with this model agreement, while lower odds for 16°C or 19°C account for minor uncertainties in cloud timing or local measurement variations at official stations.

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.
