Highest temperature in Guangzhou on July 31?

Platform comparison

Market context

The temperature recorded at Guangzhou Baiyun International Airport on 31 July will be settled by the day’s **highest reading** in degrees Celsius, and the current 0% crowd probability leaves the book effectively unpriced despite Guangzhou’s long-run tendency to run hot in late July. July norms cluster around the low 30s Celsius, with average highs near 32–33°C and record July highs reaching the mid-to-high 30s, so the market is fundamentally about whether the day clears an ordinary hot-summer band rather than whether it stays warm at all.[3][4][13][16]

Comparable July weather data suggest traders should read this as a range market rather than a binary heat spike bet. Guangzhou’s July highs are commonly around 91°F/33°C, with daily highs rarely falling below the mid-80s Fahrenheit and sometimes pushing into the mid-90s Fahrenheit; recent daily history in the city has also shown highs above 100°F/38°C during late-July heat.[3][4][1] That kind of seasonality usually supports depth only if funding is easy, because prediction-market turnover depends on deposits that clear frictionless rails and low-cost exits; onramps that accept card-linked deposits such as Klarna, plus bank transfer rails like SEPA and crypto withdrawals in USDC, tend to matter for how quickly new money reaches the book.

The main catalysts are therefore meteorological rather than macroeconomic: the local forecast path, any overnight rain or cloud cover, and whether coastal or monsoon conditions suppress the afternoon peak. Guangzhou’s July climate is typically very humid and rainy, with around 16–18 rainy days and roughly 230–260 mm of monthly rainfall, so a wet morning can still leave room for a later heat-maximising rebound if skies clear by midday.[4][18][19] Traders should watch the day’s high-resolution forecast updates and any official aviation or station observations through the settlement window, because the final print is the airport station’s maximum, not the city average.[6]
