Highest temperature in Shanghai on July 24?

Platform comparison

Market context

Shanghai’s reading will be set by the **highest temperature at Pudong International Airport** during the day, so the relevant question is whether the airport reaches a brief afternoon peak above the usual July range. Shanghai is typically hot, humid and often rainy in July, with average highs around **32°C** and frequent showers, while short-term forecasts around the date show highs in the mid-30s Celsius and substantial cloud and rain risk. That combination matters because the market resolves on the day’s maximum, not the average temperature, so even a short sunny spell can lift the final outcome. [2][3][5]

The current **0% YES** crowd price is unusually low relative to the seasonal backdrop. In a normal Shanghai July profile, a high near or above 32°C is common, and nearby forecasts have recently pointed to temperatures around **35°C** on the warmest days, with muggy conditions and intermittent precipitation. Historical comparable weather markets tend to move quickly when the forecast narrows or the observation window approaches, because the distribution becomes less about broad climate norms and more about the exact airport reading during local afternoon heat. [1][2][6]

For access and regulation, the practical framing is more important than the headline probability. A market like this can sit uneasily with **German GlüStV** rules if offered to German residents without the necessary authorisation, because the treaty tightly regulates online gambling-style products and related consumer access. In the US, the **CFTC** can reach event contracts that fall within its jurisdiction, so venue and product structure matter for any American-facing access. Where a platform advertises **“no-KYC up to $1,500”**, that usually means smaller accounts may trade or withdraw without full identity verification, but only within that cap; above it, additional checks are typically required, which directly affects how easily a trader can reach or scale into this market.
