**Trader consensus on sub-425 mm August precipitation in Hong Kong stems from official Hong Kong Observatory totals of roughly 234 mm, well below the 1991–2020 climatological normal of 453 mm.** This dry outcome reflects subdued monsoon activity and limited tropical cyclone influence, with only scattered showers rather than the prolonged heavy rain events that produced 900+ mm totals in wetter years such as 2025. Record-high temperatures and reduced cloud cover further suppressed convective rainfall. Final HKO verification data, expected imminently, will confirm resolution; any late upward revision in regional gauges remains unlikely to approach the 425 mm threshold given the month’s observed pattern.
