The weather within the watershed can be classified to three seasons:
wet, normal and dry. The wet season begins in April and ends in July.
The amount of rainfall increases from June and reaches the peak at
July. From late July, the temperature increases rapidly while the amount
of rainfall recedes. The precipitation is principally brought through
monsoon from the southeast. The normal season covers August to
November, while the dry season covers December to March. Note that
the dry season is not included in this planning due to very few farming
activities involved in the area.
