Highest temperature in Milan on July 21?

Platform comparison

Market context

The highest temperature recorded at Milan's Malpensa International Airport on 21 July 2026 will determine which temperature range resolves this market. Historical data from Wunderground provides the settlement baseline, with the measurement taken across all hours of that calendar day to establish the daily maximum.

Milan's July climate typically peaks between 28–32°C, though heat waves regularly push readings into the mid-30s. The city experienced 34°C on 21 July 2023 and 33°C on the same date in 2022, according to historical weather records. Anomalously hot summers—such as 2021, when July averages exceeded 30°C—suggest the range boundaries should account for both typical seasonal patterns and the increasing frequency of elevated temperatures across northern Italy. The 0% crowd probability likely reflects uncertainty about which specific bracket will capture the day's peak rather than doubt about temperature recording itself.

Traders should monitor European weather forecasting models from mid-July 2026, particularly those issued by ECMWF and Météo-France, which typically provide reliable ten-day outlooks for the Alpine region. Atmospheric pressure systems and any approaching heat domes from North Africa would be primary catalysts affecting whether Milan experiences a typical summer day or an exceptionally warm one. The settlement window closes at midday UTC on 21 July, allowing final adjustments based on morning forecasts before Wunderground's historical data becomes the definitive source.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

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.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

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.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
