**Real-time observations and forecast model consensus have driven near-certain trader positioning on an 18°C daily maximum for Munich on September 10.** Overcast skies, light easterly to northwesterly winds, and stable high pressure limited daytime heating, with hourly data from sources such as Yr and Meteoprog showing afternoon peaks reaching but not exceeding 18°C. This aligns with the day’s cool, cloudy pattern that kept temperatures below the long-term September average high of 20.5°C. Market-implied odds reflect this tight clustering of official station readings and model runs around that exact threshold. Only an unexpected late-day spike or post-hoc measurement revision at the primary reporting station could alter the outcome, though current data make such shifts improbable.

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.
