Official Hong Kong Observatory forecasts indicate a maximum of 28–34°C on September 30 under persistent high-level anticyclone influence, promoting subsidence, clear to mainly fine skies, and strong daytime solar heating across the region. Southwest winds of force 3 will limit mixing while low precipitation chances preserve heat buildup, consistent with late-September climatology when urban heat-island effects often push peaks into the low-to-mid 30s. Recent model runs show minimal day-to-day changes, supporting the market’s concentration on 32–34°C outcomes as the most probable resolution range ahead of any northeast monsoon shift expected after October 1.
