Indonesia has tropical climate, and diveded two season which is dry and rainy season every six month in a year; some area under equator line has 3 periode in a a year (Pontianak, Bangka Belitung, Palembang and Medan).  

In Indonesia  there are  three types of climate, that affect the namely climatic season (monsoon), tropical climate (hot climate), and marine climate.

Climate Summer (Monsoon Climate)
This type of climate is strongly influenced by seasonal winds that can vary eachperiod. Usually a change in the monsoon period is 6 months. Climate seasonconsists of 2 types, namely southwest wind season (West Monsoon) and north-eastwind season (East Monsoon). West monsoon winds blowing around October to April wet season, so bring rain / rainy. East monsoon winds blowing around the month of April to October the dry nature of the Indonesian territory have resulted in dryseason / drought.

Climate Tropical / Tropical (Hot Climate)
Areas around the equator will automatically have a tropical climate is hot and only has two seasons namely dry season and rainy season. Generally south-east Asian regionhas a tropical climate, while the European countries and North America experienceda subtropical climate. Tropical climate of Indonesia is hot so hot that invites a lot of rainfall or High Tropical Rain.

Marine Climate
Indonesia is an archipelago which has resulted in many marine areas evaporation of sea water into the air humid and high rainfall.

The high humidity caused tropical monsoon; mineral soil caused volcanos eruption in Indonesia; it made all varieties tobacco growth and it made special in quality and taste even for low grade (not interesting performance leaves).
