Recent official forecasts from Italian meteorological services and global models (including GFS and ECMWF guidance) indicate a highest temperature in Milan on August 28 most likely between 28–30 °C, with afternoon thunderstorms possible that could cap peaks through increased cloud cover, evaporative cooling, and reduced insolation. Weak easterly to southeasterly flow, high boundary-layer humidity near 70 %, and typical late-summer instability over the Po Valley create narrow margins between these thresholds, while the urban heat-island effect may add 1–2 °C locally under clearer spells. The tight clustering of market-implied odds around 28–30 °C reflects genuine model spread on convective timing and intensity rather than any single dominant signal. Updated model runs and satellite trends ahead of the daily maximum will be the next key inputs for traders.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
