Highest temperature in Milan on August 7?

Platform comparison

Market context

Polymarket currently prices this Milan temperature contract as a 34°C outcome, with the market around 49% and 33°C the main alternative at about 32%; that sits against the contract’s own settlement rule, which keys off the highest value in Weather Underground’s Daily Observations table for Malpensa, not the Day High & Low summary, and resolves in USDC via Polygon conditional tokens. With the window ending at 12:00 UTC on 7 August, traders are effectively watching whether late-morning and midday observations can still push the day’s recorded high into the upper 30s, or whether the market’s central expectation holds. [9][14]

The current read is consistent with a hot Milan summer profile, where August normals are typically in the high 20s to low 30s Celsius, but with enough headroom for sharp spikes when heat advects across the Po Valley. Forecast pages for 7 August show values around 28°C to 31°C, while live weather sources have also reflected much hotter nearby readings earlier in the week, so the contract is less about climate averages than the exact hourly path into the settlement cut-off. [2][5][6][7]

For a Polymarket user, the practical catalysts are the hourly observations published by the source station, any late revision to the Weather Underground daily table, and the timing of the first datapoint for the following date, since the market only accepts changes until that point. AccuWeather also had a yellow warning for extreme high temperature in Lombardia on 7 August, which matters mainly as a signal that the market is still sensitive to short-range heat forecasts rather than a direct settlement input.
