Highest temperature in Shanghai on August 11?

Platform comparison

Market context

Shanghai's peak temperature on 11 August 2026 will be measured at Pudong International Airport Station and recorded in Weather Underground's Daily Observations table, with settlement determined by the highest reading logged that day rather than summary forecasts. August is Shanghai's hottest month, with historical daily maxima typically ranging between 32–35°C, though heat waves can push readings above 37°C. The 0% crowd probability suggests traders view this as a certainty-level outcome—likely because the market's narrow resolution window and reliance on a single station reading creates execution friction that deters participation. Liquidity depth on weather markets often correlates with deposit accessibility; markets with higher trading volume tend to attract capital from traders using lower-friction on-ramps like SEPA transfers or USDC settlement, which reduce the effective cost of position entry and exit.

Traders monitoring this market should track China Meteorological Administration forecasts released in early August, which typically provide 10-day outlooks with reasonable accuracy for temperature ranges. Recent summers in Shanghai have seen increased volatility owing to shifting monsoon patterns; the 2023 and 2024 seasons both recorded multiple days exceeding 37°C. The specific dependency on Pudong station data—rather than city-wide averages—introduces geographic concentration risk, as airport microclimates can diverge from urban readings. Book depth will likely remain constrained until late July, when weather models stabilise and traders can confidently size positions. Payment rails matter here: markets with Klarna instalment options and SEPA withdrawal availability typically see better participation from European traders hedging exposure to Asian supply chains sensitive to heat stress.
