Highest temperature in Wuhan on August 10?

Platform comparison

Market context

The event is whether the highest temperature recorded at Wuhan Tianhe International Airport on 10 August 2026 lands in the listed Celsius range, using Weather Underground’s **Daily Observations** table as the settlement source rather than the summary high/low box. Wuhan’s August climate is normally hot: third-party climate pages put the monthly average high around 33–34°C, with record August extremes near 41°C, so the market is really about where a single day’s peak sits within an already warm distribution[3][4][5][10][18].

That backdrop helps explain why the current 0% yes probability looks detached from seasonal norms. In comparable Wuhan August datasets, daily highs commonly reach the low-to-mid 30s, and even modestly cooler outcomes still sit well above the lower buckets often offered in event markets[2][7][12][14]. For accessibility, German GlüStV treatment can matter because prediction markets may be viewed as gambling products under German law, which can affect whether local users can participate or must be screened out; in the US, CFTC reach is relevant because event contracts can attract commodity-derivatives scrutiny if they are offered to US persons. A “no-KYC up to $1,500” setup generally means smaller trades may be allowed without identity verification, but only until the platform’s threshold is reached and subject to any geo-restrictions or compliance blocks, so it affects onboarding friction rather than the weather outcome itself.

The main catalysts are the day’s actual airport observations, not the headline forecast, plus any late-morning changes in cloud cover, rainfall, or wind that can suppress or lift the day’s maximum. As of early local reporting, Wuhan was already warm with patchy rain nearby and forecast highs around the high-20s to low-30s Celsius, which leaves room for outcomes around the mid-range buckets if sunshine breaks through[15][17]. Traders should watch the airport station’s hourly progression on Weather Underground and, if available, nearby official forecasts for heat, rain bands, or convective activity that can shift the recorded peak before the settlement window closes[9][15].
