Official Hong Kong Observatory forecasts for October 7 project a daytime high of 23–30°C under a dry northeast monsoon with moderate easterly winds and mostly sunny conditions after a cooler morning start near 23°C. International models align closely, showing afternoon peaks around 28–29°C amid low humidity and light cloud cover that limits further warming. The tight market spread between 29°C (39.5%) and 30°C (30.0%) reflects genuine uncertainty in exact maximum readings, which hinge on precise wind strength, urban heat effects, and whether brief sunshine enhancements push readings to the upper end of the official range. Updated HKO guidance and afternoon observations will clarify resolution thresholds before market close.
