The most comfortable time to visit Chitwan is from October to March, when skies are relatively clear and the average daily temperature is a balmy 25°C. However, the best time to see animals is late January to March when the towering phanta grass is slashed by villagers, improving visibility considerably. At other times the grass can grow as tall as 8m, making it difficult to spot animals that may be as close as a few feet away. Jeep safaris in the park are virtually impossible during the monsoon (June to September), when tracks through the park become impassable, although they are possible in the buffer zone along the border.
Sauraha is also prone to flooding during monsoon, which caused many resorts to close during the summer of 2017, when water levels were unusually high. While some buildings were swept away, most establishments simply dried out, repainted and pressed on.
