Highest temperature in Shanghai on August 10?

Platform comparison

Market context

Shanghai’s highest temperature on 10 August will be set by the reading at Pudong International Airport, not by the summary high shown on the forecast page, so the key question is whether the station prints a value in the low-to-mid 30s Celsius or something materially cooler. Shanghai’s August climate is normally hot and humid, with averages around 32–33°C for daytime highs and repeated recent August peaks in the mid-30s, including 35.5°C on 10 August in one historical series and 35°C+ August highs in several recent years.[2][7][16][12]

The current 0% YES price implies the market is effectively discounting any qualifying heat at the airport, but comparable Shanghai summer readings show that late-morning through mid-afternoon often delivers the day’s maximum, and even a modestly cloudy or showery start does not rule out a rebound later.[1][15] For a weather contract like this, the main read-through is whether the airport station stays pinned below the lower temperature bands or whether it follows the city’s recent pattern of 34–35°C August highs, which would put the market well away from zero.[9][14][16]

For traders, the immediate catalysts are the live Shanghai Pudong observations, the timing of the afternoon warm-up, and any shift in local cloud, rain or wind that suppresses the daily high before the settlement window closes.[15][1] The funding side matters too: the book can stay thin if deposits are slowed by payment friction, while faster on-ramp routes such as card rails, SEPA, Klarna-style checkout, or USDC can improve depth by letting traders add collateral quickly around the same-day weather update cycle.
