C and humidity around 84 - 89. The wet months over 200 mm rainfall per month occur during November – April and average driest month
is August less than 100 mm rainfall per month. Average annual rainfall is about 2.400 mm. According to the Oldeman classification, the agro climate is C-1, with
the 5 to 6 wet months rainfall over 200 mm and 0-1 dry months rainfall less than 100 mm. The climate and rainfall type supports a range of crops.
The macro topography is generally flat or gently sloping towards natural drainage outlets. At micro level, the topography is very irregular and disturbed as
a result of reclamation activities, e.g. the subsidence of mineral soils and the oxidation of peat. Human activities such as leveling and construction of sorjans
further contributed to the disturbance of the original topography.
