Recent Hong Kong Observatory forecasts for late August 2026 point to normal-to-above-normal temperatures amid the long-term warming trend and lingering South China Sea troughs, positioning 31–32 °C as the most probable daily maxima for August 22. Model guidance and climatological analogs favor scattered thunderstorms and northeasterly flow that typically cap peaks near 31 °C while limiting extreme heat, consistent with the market-implied 67 % combined probability on those two outcomes. Persistent humidity and urban heat-island effects in the territory support this range, though any late intensification of tropical-cyclone activity could briefly push readings to 33 °C or higher. Updated HKO guidance and numerical model runs over the next 48 hours will be the key near-term catalysts for shifts in trader positioning.
