Market context

The Hong Kong Observatory is forecasting a maximum temperature of 33–34°C for 24 June 2026, with scattered showers and persistent high humidity likely across the region[1]. Current real-time data from the morning of 24 June already records a maximum of 33°C and a minimum of 28°C, placing the day’s average at 32.1°C under sunny conditions with a few showers[2]. This immediate alignment with the seasonal forecast suggests the market’s 0% YES probability for lower ranges is well-founded, as the day is already tracking within the upper tier of June expectations.

Historically, June in Hong Kong sees average highs between 28°C and 32°C, with July and August typically hotter at around 32°C[4]. The seasonal forecast for June–August 2026 explicitly states temperatures will be above normal, driven by current ENSO conditions and climate model guidance[6]. Given that today’s observed maximum of 33°C already exceeds the monthly average high of 31°C, traders should view the 33–34°C range as the most probable outcome, consistent with both recent form and long-term climate patterns[2][3].

Traders must monitor the finalisation of the Hong Kong Observatory’s “Daily Extract” for 24 June, which will confirm the official “Absolute Daily Max” in degrees Celsius[1]. Any sudden shift in weather warnings, such as a Typhoon Signal No. 8, could disrupt data collection and alter resolution timing, though current forecasts do not indicate such an event[5]. The key dependency is the publication of the finalized extract, which remains the sole resolution source; until this is released, the market cannot settle, and no new data points are expected to change the current trajectory[1].

Methodology

This page reviews Highest temperature in Hong Kong on June 24? across five venues. We show live odds for Polymarket-based markets (sourced from the Polygon order book); for other venues we list platform attributes, since the comparable contracts are not exposed via a public API on every venue. Every CTA points at Champions League Prediction — the application we operate, where you trade directly against the Polymarket order book at 0% fees.

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.

FAQ

Where can I trade this market with the lowest fees?

On Champions League Prediction, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
