Its name is often said to be derived from the Sundanese words of "Cai" (or river) and "Rebon" (or "shrimp"). (Indeed the main production of the city is fishery including shrimps.) The alternative Javanese derivation is from "Caruban", meaning "mixture"--a reference to Cirebon's complex mix of Javanese, Malay, Sundanese, Chinese and Arabic cultural elements. While Indonesians from outside of Cirebon pronounce the name CHEE-ray-bone, locals say Cher-BONE.
The city weather is hot and humid. Wear cotton clothes. You do not need long sleeves shirt, instead a T-shirt and knee-long trousers are comfortable. Some places like mosques (masjid) and temples require polite dress such as long trousers/skirts. Hot pants/mini skirts will attract people attention and might be considered impolite.
