Highest temperature in Shenzhen on July 21?

Platform comparison

Market context

Shenzhen's climate during late July sits firmly within its summer monsoon season, when daily highs consistently exceed 32°C. The city experiences tropical conditions driven by warm air masses from the South China Sea and frequent afternoon convection. Historical records from Bao'an International Airport show July peaks typically ranging between 33–36°C, with occasional days reaching 37°C or higher during heat waves. The 0% crowd probability suggests traders are either uncertain about the exact temperature bands available or have not yet engaged with this market in volume.

Comparable July conditions at Shenzhen Bao'an from recent years provide the baseline for calibration. In July 2023, the airport recorded multiple days above 35°C, whilst July 2022 saw sustained heat with several days reaching 36–37°C. The monsoon pattern remains the dominant driver; tropical cyclone activity in the region can occasionally suppress temperatures through cloud cover and rainfall, though this typically occurs later in the season. Current meteorological forecasts for July 2026 remain unavailable at this distance, making historical climatology the primary reference point.

Traders should monitor the Asian summer monsoon's intensity as it develops through June 2026, as stronger-than-normal monsoon circulation can influence convective activity and afternoon peak temperatures. Any tropical cyclone formation near the South China Sea in late July could introduce cloud cover that moderates daily highs. Resolution will depend entirely on Wunderground's recorded data from Bao'an station, making data availability and station operation status relevant considerations for settlement confidence.

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.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

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?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

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.
