Recent forecast models from sources like the ECMWF and GFS indicate Munich will experience clear to partly cloudy skies overnight on September 22, 2026, with light winds and dew points near 5–7°C, favoring strong radiative cooling under high pressure. This setup supports minimum temperatures around 7–8°C on average, though localized clear spells and calm conditions could drive readings to 5°C or lower in urban stations, aligning with trader emphasis on the 5°C and 4°C outcomes. The shift from warmer late-summer patterns earlier in the month, combined with northwest flow, has accelerated the seasonal decline below the 9.3°C climatological average low, though model consensus leaves room for slight upward revisions if cloud cover increases.

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.
