Market context
Shanghai’s highest temperature at Pudong Airport on 24 July will be set by the day’s peak reading, with the market resolved against Wunderground’s history page for Shanghai Pudong International Airport Station. The current 0% YES price implies the crowd is not expecting an extreme heat outcome, but that is a weak signal for a summer Shanghai reading because late-July conditions are typically hot, humid and prone to convective showers rather than decisively cool. July normals in Shanghai sit around 32°C for highs, with travel and climate guides describing the month as hot and rainy, and WeatherSpark showing muggy-day likelihood at or near 100% by late July.[3][8][9]
Comparable forecasts point to a broad 32-37°C envelope rather than any sharp cold spell. Shanghai’s short-range outlook has recently shown highs in the mid-30s Celsius, including 35°C/95°F on one day and around 37°C at maximum daytime levels in another forecast source, which is consistent with a summer pattern that can still support a high daily maximum even when showers arrive later.[1][6] That makes the practical question not whether it will be warm, but whether cloud cover, rain timing and sea-breeze effects suppress the afternoon peak below the upper-30s Celsius band.
The main trader watchlist is the intraday forecast evolution: the timing of any thunderstorms, the amount of sunshine before midday, and whether the afternoon remains dry long enough for the airport station to register its maximum before showers develop. Current hourly and ten-day guidance for Shanghai shows warm, humid air, intermittent cloud and a material chance of afternoon storms, with one source flagging 50% precipitation and another showing 0% in the present hour, so the settled high could swing by several degrees depending on when convection builds.[4][5] Airport-specific observations matter more than citywide forecasts, because a locally timed shower can cap the official maximum even if broader Shanghai stays hot.

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.
- 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.
- 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.
