As I have mentioned in all of my post, the weather in Hong Kong is unpredictable during the summer months from July to September, when the majority of thunderstorms take place. When it rains in Hong Kong it can really pour you down. Having a backup plan of what to do in case of a rainy day in Hong Kong can make sure that you will not waste days during your visit.
I have got the below suggestion for you guys to make it as a backup plan when you visit to Hong Kong.
Chinese Acupuncture Massage
Dim Sum
Museum
Afternoon Tea
Spa
