Highest temperature in Hong Kong on June 22?

Market context

Hong Kong’s 22 June maximum is being decided in the middle of a familiar early-summer pattern: hot, humid conditions with forecasts clustering around the low 30s rather than anything extreme. The Hong Kong Observatory’s June-August seasonal outlook says temperatures are expected to be above normal, while June climatology in Hong Kong is typically around 30°C by day with heavy humidity and frequent rain. [5][2]

That makes the market’s current 0% yes price look anchored to the idea that the eventual top reading will land in one of the higher bins, not because a very hot day is impossible, but because the distribution is usually tight. Recent market and forecast references point to 31–34°C as the live range, with 33°C currently the leading outcome and the Observatory’s short-range products showing around 28–32°C to 31–32°C in the city, which keeps the contest concentrated around adjacent temperature bands. [1][9][7]

For traders, the main catalysts are the final Hong Kong Observatory daily extract for 22 June and any late-day temperature surge before the settlement cut-off, because the market resolves on the Observatory’s published “Absolute Daily Max” rather than general weather sentiment. The key dependency is whether sunshine holds long enough for inland or urban sites to squeeze out one more tenth of a degree before cloud, showers or marine flow cap the peak; a change of even 0.1°C can shift the winning range once the final daily data is finalised.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Champions League Prediction, which mirrors the Polymarket order book directly.

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.
