What's the weather like in Hong Kong in late April and early May? Is it cold to wear half-sleeved shorts?

Recently, the weather in the south is not very good ~ it has been raining in Guangzhou for almost a month, and I am going to Hong Kong, so I have been paying attention to the weather in Hong Kong recently. It doesn't seem to rain as often as Guangzhou, but it's also rainy season, so it's estimated that the weather is not much better. But the temperature will not be low. Guangzhou has always been wearing summer clothes normally, and air conditioning is turned on everywhere ~ but I suggest you take a small thin coat, a pair of pants and shorts, whether it rains or not ~ ~
