Highest temperature in Shanghai on August 9?

Platform comparison

Market context

Shanghai’s top temperature on 9 August will be decided by the reading at Pudong International Airport in Weather Underground’s Daily Observations table, so the key question is not the headline forecast but whether that station ever reaches the relevant Celsius band before the settlement window closes at noon UTC. The current 0% yes price implies the book is either thin or anchored to a very low chance of a high enough station reading, despite mainstream forecasts still showing a warm August pattern for Shanghai.

That low price is easier to read against the city’s seasonal profile than against any single forecast. August climatology is hot, with typical highs around the low 30s Celsius and frequent rain, and several forecast services for 9 August currently point to heavy rain, wind and highs in the high 20s to low 30s Celsius rather than extreme heat.[1][5][7][13][16] Comparable weather markets often stay illiquid until the last 24 hours, then reprice sharply if the station forecast shifts or the observed morning temperature is already close to the relevant bracket; the friction here is mostly funding, since small books tend to move only when traders can get money in and out quickly through SEPA, Klarna-linked deposits, or USDC rails.

For catalysts, watch the final updates from major forecast providers and, more importantly, the hourly station observations around Shanghai Pudong on the morning of 9 August, because showers, cloud cover and onshore flow can cap the day’s peak temperature even if the broader city forecast looks warm.[2][5][7][14] The practical market driver is not just weather volatility but payment-flow timing: if deposit routes are slow or costly, depth usually concentrates around traders already on-platform, whereas low-friction rails can bring in fresh liquidity late, when a small move in the observed high can still reshape the order book.
