Cilegon

Cilegon is a prominent city in the Banten region of Indonesia, with a sizeable population that drives demand for detailed weather data.

Being close to the equator, Cilegon experiences a tropical rainforest climate: very warm, very humid and rainy year-round. Daytime temperatures sit between 30°C and 33°C almost every day, and rain is a regular part of life — often in the form of short but heavy afternoon storms.

During the rainy season, Cilegon can see several centimetres of rain in a single afternoon. Storms often arrive late in the day and clear by evening, leaving humid but cooler conditions overnight.

Visitors looking for the best weather in Cilegon should aim for the November–February window, when the monsoon has passed and humidity drops noticeably.

Cilegon lies near sea level, so coastal breezes and ocean-moderated temperatures play an important role in day-to-day weather.
