Hong Kong in July High summer with rain and typhoons together. Typhoons are most frequent from this month to September. With afternoon showers, thunder and high humidity, mix in indoor stops such as malls and museums.
Highs averaged 32°C and lows stayed at 27°C, so the heat hung on long after sunset. Day and night differed by only 5°C, so one outfit worked from breakfast to late dinner. Rain fell on 15 days of the month on average. Year to year it swung widely, from 7 rain days in 2007 to 23 in 2017.
Highs topped 30°C on 25 days of the month on average. Mixing in indoor stops at midday made sense. Rain days averaged 24 mm each, so when it rained it rained properly.
Typhoons i 6 of the last 20 years had a tropical storm pass within 300 km this month.
