Highest temperature in Hong Kong on August 10?

Platform comparison

Market context

Hong Kong’s highest temperature for 10 August will be set by the Hong Kong Observatory’s final “Absolute Daily Max” for the day, not by any private weather app or district reading. That matters because the Observatory’s headquarters is the settlement reference point, and recent conditions have already been extremely hot: the city logged 36.9C on 9 August, its hottest day on record, with some inland stations near 39.8C.[1][11][15]

Historically, early-August Hong Kong usually sits much lower than this. The 1991–2020 normal maximum for 10 August is 31.4C, while the Observatory’s own August 2025 report shows 10 August topped out at 34.4C, illustrating how a single hot spell can sit several degrees above climatology without approaching record territory.[4][3] That makes the current 0% YES pricing easier to read as a statement about immediate funding and position size than about the weather itself: when payment friction is low, books can deepen quickly, but if deposits are limited to slower bank rails or expensive card routes, very hot-outcome contracts can stay thin even when the forecast is extreme.

For traders, the key catalysts are the Observatory’s hourly updates, any renewed typhoon or thunderstorm signals, and the final daily extract once the day is closed out. Forecast services still show August heat near the upper 30s Celsius for Hong Kong, with showers and cloud cover capable of trimming the realised maximum if they arrive at the right time.[2][7][10] On a market venue that depends on easy top-ups and fast withdrawals, flows from Klarna, SEPA, or USDC-style rails can matter as much as the weather signal itself: cheap, rapid funding tends to pull in more participation around late-moving temperature markets, while slower on-ramp and off-ramp options usually leave depth concentrated in a smaller set of committed traders.
