Highest temperature in Shanghai on August 5?

Platform comparison

Market context

Shanghai’s airport-based reading will come down to whether 5 August peaks in the low-to-mid 30s or gets held back by cloud and showers. The current 0% yes price is hard to square with the forecast set: AccuWeather has Shanghai’s 5 August high at 89°F, while other August guides cluster around a daytime maximum near 31–32°C, and several short-range forecasts put 5 August near 34°C or 35°C.[1][3][4][13] In market terms, that leaves the temperature bucket above the consensus centre of gravity, rather than on an outlier tail.

The historical frame is important because Shanghai’s early-August weather usually sits in a tight, hot band. Long-run August averages are around 31°C to 32°C, with high humidity and frequent rainfall, and WeatherSpark notes daily highs typically stay below the mid-30s but can occasionally run higher.[10][16] That makes the relevant risk not broad seasonal cooling, but whether local convection or cloud cover clips the day’s maximum by a degree or two, which is often decisive for neighbouring outcome bands in a weather market.

Traders should watch for any late updates on showers, thunderstorms, or typhoon-influenced moisture streams, because timing matters more than total rainfall: a morning or midday spell of sun can still drive the airport reading into the mid-30s, whereas earlier cloud or rain can cap the day below model highs.[2][12] The key dependency is the official airport observation sequence at Shanghai Pudong International Airport Station on the day itself, since the market resolves to the highest temperature recorded before the next day’s first datapoint is published.[9]

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.

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.

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.
