What kind of clothes should I wear when traveling to Bali in September 14? What is the weather like there?

Bali has a tropical rainforest climate, and the annual temperature is around 30 degrees. It is recommended to bring summer clothes. In September, the local area is in the rainy season, which is very suitable for tourism. So now is the local tourist season, it is relatively difficult to book a hotel and the price will be higher. Of course, if you want to go to the mountainous area in the hinterland of Bali, the temperature will be lower than the seaside, so you can bring a sweater coat or something.
