Highest temperature in Milan on August 7?

Platform comparison

Market context

Milan’s hottest reading on 7 August is a straight temperature bet on how far the city climbs during the day, with the contract settling to the highest Celsius value recorded at Malpensa via Weather Underground’s Daily Observations table. The crowd is currently pricing **0% YES**, which is sharply lower than the live Polymarket-style framing in the search results, where the market is clustered around the **33–34°C** band rather than the upper-20s. That gap suggests either the contract has not been actively repriced on this venue or traders are treating the settlement source and airport station as materially different from generic Milan forecasts.[8][14]

Historical context points to a late-summer temperature profile that often supports the low-to-mid 30s in Milan, but with enough day-to-day spread that a single degree matters for which range resolves. AccuWeather’s August climatology shows historical highs around **82–83°F** (roughly **28–28.5°C**) for Milan, while other August outlooks put average daytime maxima near **28–30°C**; by contrast, the live forecasting market is leaning warmer, with 34°C as the leading outcome and 33°C close behind.[1][4][7][8] For a contract framed in ranges, that places the main action around whether the day peaks in the **low 30s** rather than testing the mid-30s.

The near-term catalysts are straightforward: the final settlement will depend on the actual observing conditions at Malpensa Airport, so traders should watch for any late-shift model changes, convective showers, or cloud cover that cap the afternoon high, as well as any local heat-warning messaging from Italian meteorological services. AccuWeather shows a **yellow high-temperature warning** for Lombardia running through the day, which is consistent with heat-risk conditions, but a warning does not guarantee a particular peak reading.[12] A recent forecast source also flags **patchy rain** and a **28°C** daily high for Milan on 7 August, underscoring the divergence between broader city forecasts and the airport observation that will actually settle the contract.[2]
