Highest temperature in Hong Kong on August 11?

Platform comparison

Market context

The real-world event is the Hong Kong Observatory’s official highest temperature reading for 11 August 2026, measured in Celsius and later finalised in the Daily Extract. Hong Kong’s August climate normally sits in the low 30s: the Observatory’s 1991–2020 normals show an August 11 daily mean maximum of 31.1°C, which makes a result in the low-to-mid 30s the statistical centre of gravity rather than an extreme outcome.[2]

For context, Hong Kong has recently delivered much hotter readings than its long-run August norm, including a record 36.9°C at the Observatory on 9 August 2026, reported by local and international outlets as the highest since records began in 1884.[10][5] That history matters because prediction markets on temperature ranges tend to price the most recent synoptic setup more heavily than climatology alone: in other words, a market at 0% YES can still be vulnerable to a sharp repricing if a hot spell persists, while a cooler or wetter pattern quickly pulls the likely bucket lower.[10][2]

The main catalysts are the Observatory’s short-range forecasts, hourly readings and any changes in the August weather pattern, especially showers or cloud cover that can blunt the daytime high; third-party forecast pages on 11 August pointed to a hot but unsettled day, with highs around the mid-30s and some shower risk.[6][11] On the market-access side, German GlüStV treatment depends on whether the venue is deemed an authorised gambling product under German rules, while the CFTC’s reach is relevant if a US person-facing platform offers commodity-style event contracts into the United States; the “no-KYC up to $1,500” feature means smaller positions may be opened with lighter identity checks, but it does not remove any jurisdictional or account-level limits that still apply to this specific market.
