Highest temperature in Shenzhen on July 23?

Platform comparison

Market context

Shenzhen’s temperature is set by the classic July trade-off: intense heat is normal, but cloud, showers and typhoon-driven rain can cap the day’s peak. Long-run July averages put daytime highs around 31-32°C, with humidity and rainfall high enough to keep conditions volatile rather than persistently extreme.[1][4]

That makes the current 0% YES price look more like a reflection of the settlement wording than a view on weather. On a typical Shenzhen July day, the airport station can still reach the low 30s Celsius even in a wet month, but the exact market resolves on the single highest reading at Shenzhen Bao'an International Airport, so a brief sunny break or delayed storm band matters more than the daily mean.[1][4]

For traders, the key catalysts are the local forecast into the afternoon, any rainband or thunderstorm timing over the Pearl River Delta, and whether marine or typhoon-related cloud cover lingers over the airport. Current conditions are already hot, with Shenzhen reporting clear weather and a temperature of 84°F, while the RealFeel is materially higher at 96°F because of humidity, which shows the air mass is warm enough for a meaningful upside move if sunshine persists.[2]

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.

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.
