**Official forecasts from the Hong Kong Observatory indicate a mainly fine October 1 with extreme heat possible in parts of the territory before turning cloudy with isolated showers or thunderstorms later, supporting a daytime maximum range of 29–34°C.** This aligns with the market’s leading outcomes at 33°C (54.5%) and 34°C (31.0%), as persistent light winds and limited cloud cover early in the day favor peak readings near the upper end of the guidance. Recent model consensus and historical analogs for early October under similar synoptic patterns reinforce the elevated temperatures, though afternoon convection could cap the high slightly below 34°C in some scenarios. The implied probabilities reflect trader assessment of these variables ahead of official verification.
