Highest temperature in Shenzhen on August 15?

Platform comparison

Market context

On 15 August 2026, the highest temperature recorded at Shenzhen Bao'an International Airport Station will determine the settlement range for this market. The crowd currently assigns zero probability to the YES outcome, suggesting consensus expects temperatures to fall below the threshold specified in the market's range options. Shenzhen's August climate is characterised by intense summer heat and high humidity, with daily highs typically ranging between 32–34°C, though extremes occasionally exceed 35°C during heat waves.

Historical August temperature data from Shenzhen shows considerable year-to-year variation. The city has experienced multiple days exceeding 35°C in August across recent decades, with some peaks reaching 36–37°C during particularly intense heat events. The 0% crowd probability suggests either the YES range sits unusually high relative to typical August maxima, or traders are anchoring heavily to recent cooler patterns. Given Shenzhen's consistent August heat profile and the frequency of days surpassing 34°C, the current consensus warrants scrutiny—especially if the YES threshold aligns with historical norms rather than extreme outliers.

Traders should monitor tropical cyclone activity in the Western Pacific during early-to-mid August 2026, as storm systems can suppress temperatures significantly. The China Meteorological Administration typically issues seasonal forecasts by late July, providing guidance on whether August 2026 will trend warmer or cooler than the 30-year average. Any official heat wave warnings issued in the fortnight preceding 15 August would signal elevated probability for higher temperature ranges. Resolution depends entirely on Weather Underground's Daily Observations table from Bao'an station, making data source reliability the critical dependency.

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.
