What's the weather like in Sydney in summer?

I have been in Sydney for 8 years. Answer this question.

The first thing to say is that the ultraviolet rays in Australia are very strong, so you must wear sunscreen when you go out in summer. Once I went fishing in gloomy weather and got sunburned. It only took a whole week.

Anyway, summer in Sydney is generally not too painful. It must be sunny, but it won't be too stuffy. It's a little cooler indoors and in a cool place. Summer nights in Sydney are quite comfortable. When I was sleeping, a cool breeze blew in from the screen window of the balcony, so cold that I had to cover myself with a thin quilt.
