beware about changing season on the sea. should be noticed, the best visiting karimunjawa is on musim timur [east season] not the opposite or changing weather into first and second monsoon periods. in this case will happened tidal waves with unpredictable weather [sunny then shower rain and the worst is thunderstorm]. our greatest experience about changing monsoon just happened at the first day we stay at fishing platform. thunderstorm!!!! and the rest >> we get clear water and sunny days. thank God :)
watch out for this creatures when you're snorkeling. they're usually among the corals in groups. some of them are white and the others are black.
