Indonesia lies between two major continents, Asia and Australia, and between two oceans, India and the Pacific. This strategic position caused Indonesia to be deeply influenced by the muson wind system. Therefore, the season in Indonesia is determined especially by the direction of the muson wind that changes twice a year.
In addition, where Indonesia lies in the equator means the difference between sunlight acceptance between summer and winter is not too great. As a result, there's no snow or fall like the middle climate countries. The temperature in Indonesia is relatively stable throughout the year between 25-35 ° C in the lowlands.
Rain in Indonesia
The rainy season in Indonesia is common between October and April. However, time begins and ends differently in every region. The western region of Indonesia, like Sumatra and Java West, experienced an even earlier monsoon than the east.

Pancaroba is the transition between the monsoon and the drought. In Indonesia, pankaroba happens twice a year, which is April May.
During pankaroba, the weather is very erratic and unpredictable. The morning can be very hot and sunny, but suddenly heavy rain comes with strong winds. In addition, the winds of the pottery often occur during pancaroba due to high atmospheric instability.
