Weather Conditions in September

Mid-September marks the start of the ‘Fall Season’ historically the monsoon would end in mid-September, however in recent years the monsoon has officially withdrawn in early October. While there is a good chance of precipitation, clear skies and lush, rice paddy terraced hills are your spectacular when it is not raining. The chance of rain decreases as the month progresses. The end of the monsoon means there is still a chance of the occasional heavy snowfall at high altitudes. Furthermore, high passes can have a lot of snow that has accumulated over the monsoon.
