Current dry anticyclonic conditions over southern China, combined with an easterly flow expected to limit convection, position the 70-120 mm range as the dominant outcome for October total precipitation in Hong Kong. Official Hong Kong Observatory data show roughly 77 mm accumulated through mid-month against the 1991-2020 climatological normal of 120.3 mm, while model guidance indicates only isolated light showers or trace amounts for the remainder of the period. Tropical cyclone activity remains suppressed by cooling sea-surface temperatures and unfavorable upper-level dynamics, reducing the likelihood of heavy rainfall episodes that would push totals above 120 mm. These factors align trader-implied odds with a near-normal but slightly drier finish.
