Climate in Bali
The best way to explain the climate and weather in Bali in a year period is based on traditional Caka Calendar. Each month (sasih) in this calendar has its own climate and weather characteristic. Balinese have used these climate and weather characteristics to determine the best time for cultivating the land or to perform a religious ceremony.
A year in the traditional Caka calendar consist of twelve months. Here are the months arranged in succession as follows Kasa, Karo, Katiga, Kapat, Kalima, Kenem, Kapitu, Kaulu, Kasanga, Kadasa, Jiyestha and Asada. The prefix of ka– in the first tenth months above refers to ordinal numbers. The first month (kasa) of the traditional Caka calendar corresponds to July. But they are not exactly the same since the traditional Caka calendar is a lunar calendar while the Gregorian is a solar one.
