Hong Kong in June

The wettest month of the year. Rainstorm warnings rise from amber to red to black, and at black it is best to stay somewhere safe indoors. Dragon boat races for Tuen Ng are usually in June.

June brought serious heat to Hong Kong, 31°C on a typical afternoon and 27°C overnight. Early mornings were the best time to be outside. With just 4°C between afternoon and night, the evening felt like a continuation of the day. The month averaged 17 rain days. Carry an umbrella. The average is 17, but individual years ran from 8 (2015) to 23 (2008).

Highs topped 30°C on 20 days of the month on average. Mixing in indoor stops at midday made sense. Rain days averaged 29 mm each, so when it rained it rained properly.
