Highest temperature in Hong Kong on August 14?

Platform comparison

Market context

The real-world event is the highest official temperature recorded by the Hong Kong Observatory for Hong Kong on 14 August, reported to one decimal place in the Daily Extract. The market is therefore driven by the day’s peak reading rather than a forecast average, and settlement will wait until the observatory publishes final data for that date.

A 0% crowd-implied probability on any specific outcome is most useful as a liquidity signal, not a weather view. Hong Kong’s August maxima often sit in the high 20s to low 30s Celsius, and recent market pricing has clustered around 30°C and 31°C, which is consistent with the Observatory and other forecast services showing showers and moderated peak heat rather than an extreme spike.[2][3][6][9][10] The current depth is also being formed against a backdrop of very recent heat volatility: the Observatory said Hong Kong posted 36.9°C on Sunday, with some outlying stations above 39°C, showing that even in a humid monsoon regime the top-end can move quickly when a hot airstream takes hold.[4][8][12]

For traders, the key catalysts are the morning and early-afternoon Observatory updates, any thunderstorm or typhoon signal changes, and whether cloud, rain or a southwesterly flow suppresses the daily maximum.[1][11] On a payments-led venue, book depth is also shaped by funding friction: deposits that clear quickly through Klarna, SEPA, or USDC tend to support tighter spreads and faster repricing, while slower on-ramp and withdrawal rails can leave the market thin until larger balances arrive.
