Recent forecasts from multiple meteorological models converge on a high of 23–24°C for Milan on September 23, driven by easterly flow under high pressure that limits daytime heating while maintaining clear to partly cloudy conditions. This aligns with the market-implied probabilities favoring those two outcomes at nearly 80% combined, reflecting trader assessment of model consensus and limited variability in steering patterns or cloud cover. Historical September averages near 22–23°C provide context, with current guidance showing modest cooling from recent days rather than any anomalous warmth or cold advection. Updated runs from European and global ensembles over the next 24–48 hours will refine the exact maximum before resolution.

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=limc
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.
