Northeast monsoon flow following a recent cold front has established cooler, drier conditions over Hong Kong, with official Hong Kong Observatory forecasts indicating a minimum of 23°C for October 7 under mainly fine skies and northeast winds of force 4–5. Clear nights promote strong radiative cooling, widening the diurnal range and supporting urban lows near 23°C while New Territories sites trend a degree or two cooler. Model consensus and recent observations align with this range rather than deeper cooling or rapid rebound, though minor shifts in wind strength or cloud cover could adjust the exact minimum. Traders appear to weight the latest guidance heavily, with 23°C and 24°C capturing the bulk of implied probability ahead of the next forecast updates.
