The air might not feel too cool as there are still a lot of humidity and rain but it is a lot better than the past months gone by. This is one of the more comfortable of the hot months in Cambodia. The rainfall continues in all the regions of the country more or less. September is one of the wettest months of Cambodia and one can expect rain all day long for days with just little breaks in between.

The rain is so heavy those even tourists do not like the visit the country in this month of the year. The temperature might be at almost 27°C and when there is heavy rain it might drop even more. The greenery continues to blossom in this month as well. The rain and monsoon provide a good time for vegetation while the sun coming out in between plays its part as well.
