Latest ensemble forecasts from ECMWF and GFS models indicate a high of 22–23°C in Milan on September 25 under mostly cloudy skies with light easterly flow and only a low chance of brief drizzle. This aligns with a post-perturbation stabilization as high pressure rebuilds across the Po Valley, limiting daytime heating while keeping overnight lows near 16°C. Recent model runs show tight clustering around these values, with minimal spread due to consistent steering patterns and moderate humidity levels that suppress stronger warming. Trader consensus at 22°C (34%) and 23°C (28%) reflects this narrow uncertainty band, with slight downside risk if cloud cover thickens more than expected; final resolution will hinge on the official maximum recorded by local stations.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Malpensa Intl Airport Station in degrees Celsius on 25 Sep '26.
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.Latest ensemble forecasts from ECMWF and GFS models indicate a high of 22–23°C in Milan on September 25 under mostly cloudy skies with light easterly flow and only a low chance of brief drizzle.
