Lowest temperature in Hong Kong on August 10?

Platform comparison

Market context

The event is the **lowest temperature** recorded by the Hong Kong Observatory on 10 August 2026, reported in Celsius to one decimal place and resolved from the Observatory’s “Absolute Daily Min (deg. C)” in the daily extract once finalised.[1][6] That structure matters because the market does not settle on a forecast low, but on the official observation after the day closes and the dataset is published.[1][6]

The current **0% YES** crowd price sits against a Hong Kong August climatology that is usually very warm, with normal 10 August mean minimum temperatures around **26.3°C** and mean temperatures near **28.7°C** at the Observatory.[3] Recent comparable August readings have also been hot: the Observatory’s 2025 monthly summary says 10 August reached **34.4°C**, while 2024’s August summary described the period as exceptionally hot, with the month’s mean minimum at **27.7°C**.[9][14] By contrast, broader historical weather pages still show that Hong Kong can occasionally post cooler August lows, but those are typically exceptional rather than typical summer outcomes.[5][7]

For accessibility and compliance, the relevant framing is that a market like this sits in a regulatory grey zone: German **GlüStV** issues depend on whether a platform is treated as offering gambling to users in Germany, while the US **CFTC** has asserted broad reach over certain event contracts that touch US persons or US-linked activity.[3][7] On the platform side, “**no-KYC up to $1,500**” generally means a user can access small-stakes trading without full identity verification until cumulative activity crosses that threshold, which affects friction rather than the underlying resolution source.[1][6] Traders still need to watch the Hong Kong Observatory’s publication timing, because this market cannot resolve until the official daily extract is posted and the minimum temperature is confirmed.[1][6]
