Highest temperature in Shanghai on August 2?

Platform comparison

Market context

Shanghai’s hottest reading on 2 August will be shaped by whether the city gets another humid, summer-time spike rather than by any long-lived seasonal change. August in Shanghai is normally one of the warmest months, with typical daily highs around 32–35°C and occasional extremes above 40°C in the city’s historical record, so a high somewhere in the low-to-mid 30s is the most natural reference point for this market.[2][5][8]

That matters for reading the current **0% YES** crowd price: the market only resolves if Shanghai Pudong International Airport Station’s *highest* temperature falls into the specific range selected by the contract, so even a hot day can still miss if the final peak lands outside that bucket. Comparable August profiles show Shanghai often finishing near 30–35°C, but short-range forecasts for early August 2026 have already shown daily highs in the low 30s rather than persistent extreme heat, which helps explain why traders may be pricing a narrow outcome rather than a broad “hot day” view.[9][10][17]

For traders, the main catalysts are the day’s forecast updates, any abrupt shift in rainfall, cloud cover or typhoon-adjacent weather, and the airport station’s official hourly peak as it develops through the morning and early afternoon Beijing time. In a payment-friction-led book, fresh deposits matter: easier funding through Klarna, SEPA and USDC can deepen order books quickly, but withdrawal rails and transfer delays can also leave liquidity uneven if traders cannot recycle capital in time. The practical watchpoint is whether late model runs or a sudden convective burst push the airport’s top temperature into a different settlement band before the window closes at midday UTC, when the final value is effectively locked.[18]
