Recent numerical weather prediction models, including GFS runs, indicate a minimum temperature near 12°C for Munich on September 17, driven by clearing skies after frontal rain on the 16th, light westerly winds, and moderate radiative cooling overnight. This setup favors boundary-layer temperatures in the 11–13°C range, though ensemble spread arises from uncertainties in cloud cover persistence and subtle warm-air advection. Trader odds remain closely divided between sub-9°C outcomes and milder readings above 15°C because small forecast adjustments in dew points or wind mixing can shift the low by several degrees. Official verification will rely on Munich-area station observations, with the next model updates likely refining the overnight minimum ahead of resolution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
