What's the weather like in Sydney, Australia in early January? About how many degrees?

The weather in January is very hot. You can think of it as July and August in China, but it's disgusting in Australia. . . It will be colder when it rains, about 17 or 8 degrees. Therefore, you should bring some long-sleeved trousers, single clothes, and short-sleeved shorts. The hottest temperature is over 4 degrees, and you should bring some cool clothes.
