Official forecasts from the Hong Kong Observatory indicate a minimum temperature of 28°C on September 29 under a high-pressure anticyclone delivering mainly fine, very hot conditions with southwest winds of force 3–4. Multiple model runs and regional outlooks align on overnight lows near 28°C amid elevated humidity and minimal cloud cover, consistent with late-September climatology where seasonal cooling is offset by persistent subtropical warmth. Trader consensus favoring 28°C at 50% implied probability reflects this stable pattern, though slight downward revisions remain possible if northeast monsoon influence strengthens earlier than projected or if localized urban heat effects vary measurements. Updated HKO briefings and model consensus through September 28 will provide the next key data points for resolution.
