I'm going to Hawaii for the Spring Festival. What was the climate like then?

I went to Hawaii in summer, where the weather was basically spring or summer, and it was not very hot in the morning. The residents there are basically not equipped with air conditioning, because it is cool at night, the sea breeze is comfortable and there are no mosquitoes. Basically, you can bring clothes in summer and spring. Of course, you still need to take some coats. It's cold when it rains. The weather is a bit unpredictable. Sometimes it suddenly clears up when it rains, and it's basically not too cold, but if you go in winter, you should take some thick clothes just in case.
