Highest temperature in Milan on July 31?

Platform comparison

Market context

Milan’s late-July temperature market turns on whether the day at Malpensa Airport produces a notable afternoon high before the 12:00 UTC cut-off, with the forecast effectively tied to the strength and timing of any hot spell over northern Italy. Seasonal normals put Milan’s July daytime highs around 29°C, while historical records show the city can occasionally move well above that, with July extremes in the high 30s Celsius[5][6][13].

That is the right frame for the current 0% YES pricing: it implies the crowd sees little chance of an unusually hot reading at the airport station, but Milan’s climate also has a meaningful warm-tail history, including extreme episodes such as the 2023 heat event in which Milan set a record for its highest average daily temperature in 260 years[18]. For a market like this, the key is not the average July climate but whether synoptic conditions deliver sustained sun, weak wind and trapped warm air long enough for the station’s maximum to reach the settlement band[5][13].

Traders should watch the local forecast updates for Milan and Lombardy, any heat alerts from Italian meteorological services, and the daily temperature curve at Malpensa rather than central Milan, because airport conditions can differ from the urban core. The practical catalysts are the timing of peak heat, cloud cover and thunderstorm development, since a late-afternoon convection shift can cap the maximum even when the broader day starts hot[4][12][13].

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
