June begins the long summer in Hong Kong and is the wettest month of the year with an abundant 457.2mm (18") of rain in the space of 20 days. Heavy rain with thunderstorms is a feature of the hot and humid weather as the sun breaks the cloud cover for 5 hours a day. The average temperatures are in the range of 26.1°C (79°F) to 30°C (86°F) with a few days that go past 32.2°C (90°F).
The southern winds and the urban wall effect step up the heat in Hong Kong, as it becomes uncomfortable without air-conditioners. Tropical cyclone season starts from June and poses a threat with thunderstorms, strong winds, floods, and landslides.
Beat the heat with a trip to Ocean Park with thrill rides, giant pandas and a classy aquarium with numerous fish and turtle species. The Dragon Boat Festival is a major attraction for western tourists, and it is advisable to wear light sweatshirts and carry an umbrella in the wet conditions.
