What's the weather like in Hong Kong now?

If you only go out in the afternoon or all day, you can wear it like this; If you go out early, you'd better take an extra coat, because it's cold in the morning and evening; And if you go to the top of the mountain at night, it's windy and take an extra coat (the air conditioning in indoor places such as shopping malls is quite cold). Also, it may rain, please take an umbrella (it's 22/23 degrees in the morning and 29 degrees in the afternoon today).
