The transition periods between the wet and dry seasons experience moderate rainfall.

Influence of Topography and Ocean Currents

Rangkasbitung’s proximity to the Indian Ocean and its location within a mountainous area significantly impact its rainfall patterns. The presence of the Indian Ocean provides ample moisture for rainfall formation. As the air masses move inland, they encounter the Barisan Mountains, which force them to rise and cool, leading to condensation and precipitation. Consequently, the western slopes of the mountains receive higher rainfall compared to the eastern slopes. Additionally, the interaction between the ocean currents and the topography creates local wind patterns that influence rainfall distribution, resulting in variations within the region.
