Highest temperature in Wuhan on August 11?

Platform comparison

Market context

Wuhan will experience peak summer heat on 11 August 2026, with the settlement hinging on the highest temperature recorded at Wuhan Tianhe International Airport Station. The market currently implies near-zero probability of any specific outcome resolving, suggesting either extreme uncertainty about the exact temperature range or insufficient trader engagement with the specific resolution mechanics. Settlement will draw from Weather Underground's Daily Observations table rather than summary figures, a distinction that matters when hourly readings diverge from rounded daily highs.

Historical August temperatures in Wuhan cluster consistently in the 32–37°C range during mid-summer, with occasional peaks above 38°C during particularly intense heat waves. Data from the past decade shows that extreme heat events—those exceeding 39°C—occur roughly once every three to four years in August, making such outcomes statistically plausible but not routine. The 0% crowd probability suggests traders may be waiting for clearer atmospheric forecasting or treating this as a low-liquidity market.

Traders should monitor seasonal weather patterns emerging in June and July 2026, particularly any signals of an unusually strong Pacific high-pressure system or tropical moisture patterns that could amplify Wuhan's summer heat. The city's location in the Yangtze River valley creates a natural heat-trapping geography, and any La Niña or neutral ENSO conditions favouring continental warming would increase the likelihood of above-average August temperatures. Real-time forecast updates from China's meteorological authority typically become reliable only 10–14 days before the settlement date.

UK Frequently Asked Questions

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
