Recent forecasts from European and U.S. models indicate Munich’s September 11 maximum will likely reach 18–20 °C under mostly cloudy skies and light northwesterly flow following a frontal passage. Persistent stratiform cloud and modest boundary-layer mixing are limiting daytime solar heating, while surface high pressure building from the east supports gradual stabilization and reduced precipitation chances. Historical climatology places the long-term average high near 20 °C, so current guidance sits close to that baseline. With model spreads remaining narrow and no significant warm-air advection expected, trader consensus clusters tightly on 19 °C as the modal outcome, reflecting the balance between residual moisture and stabilizing subsidence. Updated runs from DWD and ECMWF on September 10 will refine the exact ceiling.

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.
