Climate - Chitwan National Park
The park has a range of climatic seasons each offering unique experience. October through February with average temperature of 25C offers an enjoyable climate. From March to June temperatures can reach as high as 43*C. The hot humid days give way to the monsoon season that typically lasts from late June until September when rivers become flooded and most of the roads are virtually impassable. Mean annual rainfall of the park has been recorded 2150mm.
In late January, local villagers are allowed to cut thatch grasses to meet their needs, which offer a better viewing of wildlife to visitors. Also, between September and November, and February and April, migratory birds join the residential birds and create spectacular bird watching opportunities. While the monsoon rains bring lush vegetation, most trees flower in late winter. The palash tree, known as the "flame of the forest", and silk cotton tree have spectacular crimson flowers that can be seen from a distance.
