Highest temperature in Wuhan on August 20?

Platform comparison

Market context

On 20 August 2026, the highest temperature recorded at Wuhan Tianhe International Airport Station will determine the settlement outcome for this market. Wuhan experiences a humid subtropical climate with August typically among its hottest months, when daily highs regularly exceed 35°C. The resolution will draw from Weather Underground's Daily Observations table rather than summary figures, establishing a precise measurement standard that eliminates ambiguity between different reporting formats.

Historical August temperatures in Wuhan provide essential context for assessing probability ranges. Over the past two decades, August highs at the airport station have consistently fallen between 32°C and 38°C, with extreme readings above 40°C occurring only during exceptional heatwave conditions. The 0% crowd probability suggests traders are pricing in either unusually cool conditions for mid-August or scepticism about specific temperature thresholds embedded in the market's range options. Comparable weather patterns from 2013 and 2017—years when Wuhan experienced significant summer heat—recorded peak temperatures of 39–40°C, establishing a baseline for understanding what constitutes genuinely exceptional heat.

Traders should monitor long-range weather forecasting updates from June onwards, as seasonal climate patterns become clearer. The El Niño or La Niña status in early 2026 will influence broader East Asian temperature trends. Additionally, any significant urban heat island effects from ongoing development in Wuhan's metropolitan area could marginally elevate readings at the airport station. Weather Underground's historical data consistency and the airport's standardised measurement protocols make this resolution source reliable, though traders should verify current station operational status closer to the settlement date.

UK Frequently Asked Questions

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Election Predictions UK route into the same order book at 0% fees.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
