Many people regard these as the best months of the year. January and February are cloudier, with occasional cold fronts followed by dry northerly winds. It is not uncommon for temperatures to drop below 10 °C in urban areas. The lowest temperature recorded at the Observatory is 0 °C , although sub-zero temperatures and frost occur at times on high ground and in the New Territories.

May to August are hot and humid with occasional showers and thunderstorms, particularly during the mornings. Afternoon temperatures often exceed 31 °C whereas at night, temperatures generally remain around 26 °C with high humidity. There is usually a fine dry spell in July which may possibly last for one to two weeks, or for even longer in some years.
September is the month during which Hong Kong is most likely to be affected by tropical cyclones, although gales are not unusual at any time between May and November.
About 80 percent of the rain falls between May and September. The wettest month is August, the driest month is January.
