Highest temperature in Wuhan on August 20?

Platform comparison

Market context

Wuhan's August weather patterns show consistent extreme heat, with daily highs regularly exceeding 35°C during mid-August. The city sits in a region known as one of China's "furnaces," where prolonged high-pressure systems and urban heat effects drive temperatures substantially above national averages. Historical data from Wuhan Tianhe International Airport indicates that 20 August typically falls within the peak summer period, with recorded highs between 33–37°C over the past decade, though occasional spikes above 38°C occur during particularly intense heatwaves.

The 0% crowd probability reflects uncertainty about which specific temperature band will be recorded rather than doubt about whether heat will occur. August 20 falls outside the immediate forecast window, making prediction dependent on seasonal patterns and longer-range atmospheric models that remain unreliable beyond two weeks. Traders should monitor late-July and early-August 2026 weather data from Wuhan to assess whether monsoon patterns or anomalous circulation systems are establishing themselves, as these conditions shape the final weeks of summer.

Resolution hinges on the Daily Observations table at Weather Underground for Wuhan Tianhe station, which records sub-daily temperature readings rather than simple daily highs. This distinction matters: peak temperatures often occur in mid-afternoon and may differ from summary figures. Traders should verify the specific measurement methodology used by the station and confirm whether any equipment changes or station relocations occur before August 2026, as these could affect recorded values.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

UK Frequently Asked Questions

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

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%.
