Highest temperature in Shanghai on August 9?

Platform comparison

Market context

Shanghai’s high on 9 August will be settled by the **highest temperature recorded at Shanghai Pudong International Airport Station** in Weather Underground’s *Daily Observations* table, not the headline day-high figure. Current forecasts lean wet and less hot than a typical August peak: AccuWeather shows a **85°F / 29°C** high with heavy rain, while other forecast services cluster around the high 20s to low 30s Celsius rather than the mid-30s that can occur in Shanghai’s late-summer heat.[2][3][6][9] That makes the market’s **0% YES** crowd price easy to read as a statement that traders are not yet paying for a hotter-than-forecast outcome, even though the event can still resolve on a brief observation spike if conditions are unstable around convective rain and humidity.

For context, Shanghai in August is usually hot and muggy, with typical highs around the low 30s Celsius and a meaningful tail risk of much higher readings during clear, stagnant spells.[14][16] Comparable forecast patterns matter because the market resolves on a single station observation, so a forecasted “high” near 29–33°C does not rule out a short-lived higher reading if sunshine breaks through or the airport station records a pre-rain warm-up.[3][6][12] For accessibility, “**no-KYC up to $1,500**” generally means a user can trade up to that lifetime or platform-defined threshold without submitting identity documents, but larger activity can trigger verification; for German users, the GlüStV framework is relevant because it treats many betting-style products as regulated gambling, while US users may still face CFTC reach where a market is viewed as a derivatives or event contract product, regardless of where the venue is based.
