Highest temperature in Wuhan on July 19?

Platform comparison

Market context

Wuhan's peak temperature on 19 July 2026 will be measured at Tianhe International Airport Station and resolved against historical weather records. The settlement window closes at midday UTC on that date, capturing the full diurnal cycle for the day in question. Current crowd-implied probability sits at 0%, suggesting either extreme confidence in a specific temperature range or insufficient liquidity across the contract's resolution brackets.

Wuhan experiences pronounced summer heat, with July typically the hottest month. Historical data from the past decade shows peak temperatures in mid-July ranging between 35–39°C, with occasional excursions above 40°C during heat waves. The 2013 heat wave pushed readings to 40.3°C; more recently, July 2022 recorded sustained peaks near 37–38°C. These precedents establish the baseline distribution against which traders should calibrate their expectations for 2026.

The primary catalyst affecting this outcome remains atmospheric circulation patterns and any developing heat dome systems across East Asia in mid-July 2026. China's meteorological forecasts, typically issued 10–14 days ahead, will provide the most actionable signal. Traders should monitor whether El Niño or La Niña conditions persist into northern hemisphere summer, as these influence regional pressure systems. Current cross-platform comparison shows minimal divergence because most prediction markets and weather-focused betting platforms have not yet populated meaningful odds for this specific date, leaving the 0% reading as a liquidity artifact rather than genuine consensus.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
