Highest temperature in Hong Kong on August 15?

Traders currently price "31°C" at 100% for "Highest temperature in Hong Kong on August 15?". Over the past 24 hours that probability moved up 60.3 points. Full distribution: 31°C 100%, 32°C 0%, 33°C 0%, 30°C 0%. The market has traded $250K in total volume and resolves Aug 15, 2026. **Official Hong Kong Observatory forecasts and current conditions point to a maximum of around 31°C today, driving the overwhelming market consensus.** Persistent southwesterly flow combined with increased cloud cover, scattered showers, and thunderstorm activity has moderated daytime heating across the territory. This aligns with typical mid-August climatology, where average highs hover near 31°C amid high humidity and frequent convective rain. Recent model runs and HKO guidance emphasize light to moderate precipitation chances (70–95%) that limit solar insolation and cap temperatures, consistent with post-typhoon stabilization after earlier extreme heat. Realistic challenges include rapid clearing of clouds allowing stronger afternoon heating to push readings to 32°C, or localized urban heat-island effects elevating official readings. Updated HKO bulletins or revised numerical weather prediction outputs remain the key near-term catalysts that could shift the narrow probability tails.
