Recent forecasts from the Hong Kong Observatory indicate a minimum temperature of 29°C for October 1, with sunny periods, very hot daytime conditions, and a few showers possible later under light winds. This aligns closely with the market's leading 28°C outcome at 55.5% implied probability, as model runs show minor variations in overnight cooling influenced by humidity near 65–90% and potential cloud cover. The 29°C and 27°C options at 23.5% and 13.5% capture uncertainty around shower timing and the transition toward a northeast monsoon, which typically moderates temperatures but has not yet strengthened. Historical early-October minima average near 27°C, providing context for trader focus on short-term observational updates from official monitoring stations ahead of resolution.
