Situated astride the equator, Indonesia experiences a tropical climate. Wet Season: November - April Dry Season: May - October Temperatures are hotter along the coast and more moderate at higher elevations. Humidity remains high with a yearly average of 70-90%. Rainfall can occur at any time of the year but is higher in the mountainous areas where there is very little distinction between the wet and dry seasons. Central Indonesia is the driest area. Due to its southerly position, Indonesia is not prone to cyclones or typhoons but thunderstorms are quite common. Carry a lightweight jumper as it can be chillingly cold inside air-conditioned buildings.   HAZE - In recent years Indonesia has suffered from the phenomena known in Asia as "Haze". Caused in part by forest fires and out of control "slash and burn" practices in both Indonesia and Malaysia - late Summer/early Autumn have seen sunny skies obscured for days and poor air quality. Haze is difficult to predict, however efforts are being made to prevent a recurrence of the severe hazes of 1996 and 1997.     Western Indonesia Padang   Average temperature     Average rainfall   Wet Season November-April 22 - 31oC 380mm Dry Season May - October 23 - 31oC 316mm Central Kalimantan, Jakarta, Java, Sumatra Primarily due to the elevation of much of the land, this is the wettest region of Indonesia.
