**Trader consensus on a 27°C high for Milan on September 15 reflects the strong alignment of official forecasts and real-time observations under clear skies and light easterly flow.** Multiple meteorological models and station data project an afternoon peak near 27°C (roughly 81°F), with minimal cloud cover and negligible precipitation risk keeping temperatures from exceeding this threshold. This exceeds the September climatological average of about 24°C, driven by a transient ridge of high pressure and warmer-than-normal boundary-layer air. Market-implied odds near 100% for exactly 27°C capture the narrow range of expected outcomes, though minor uncertainty remains around precise station maxima or brief late-day cooling if marine influences strengthen. New observational updates from regional networks or any rapid model adjustments could still shift resolution if conditions deviate.

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 15 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.**Trader consensus on a 27°C high for Milan on September 15 reflects the strong alignment of official forecasts and real-time observations under clear skies and light easterly flow.** Multiple meteorological models and station data project an afternoon peak near 27°C (roughly 81°F), with minimal cloud cover and negligible precipitation risk keeping temperatures from exceeding this threshold.
