Highest temperature in Hong Kong on August 14?

Platform comparison

Market context

On 14 August 2026, the Hong Kong Observatory will record the day's highest temperature in degrees Celsius. This market resolves to whichever temperature band contains that single daily maximum reading, published in the Observatory's official Daily Extract once data is finalised. The settlement window closes at 12:00 UTC on that date, though resolution may be delayed pending the Observatory's publication schedule.

Hong Kong's August temperatures are remarkably consistent year-on-year, with historical daily maxima clustering between 31–34°C during the summer monsoon season. The 0% crowd probability reflects either extreme confidence in a specific range or sparse trading activity; comparable weather markets on established platforms show that temperature-band markets typically attract modest liquidity unless tied to record-breaking conditions or significant insurance hedging demand. August 2025 saw Hong Kong peak at 33.8°C on the 13th and 34.1°C on the 14th, providing a recent baseline against which traders can calibrate expectations.

From a regulatory standpoint, this market's accessibility depends on trader jurisdiction and account status. Under German GlüStV rules, prediction markets on weather events face stricter classification if marketed to German residents; US CFTC oversight applies to binary derivatives on physical commodities (including temperature indices), though weather prediction markets have historically occupied a grey zone when structured as information markets rather than financial derivatives. Platforms offering no-KYC access up to $1,500 notional exposure typically treat weather markets as lower-risk for AML purposes, since payoffs are tied to objective Observatory data rather than subjective outcomes. Traders should verify their platform's specific regulatory framework before positioning, as cross-border enforcement of weather-market rules remains inconsistent.
