The circuit has two (2) distinct seasons: the wet season which is characterized by abundant rainfall brought about by the southwest monsoon, and the dry season which is characterized by the striking low rainfall due to passing of the northeast monsoon over the Cordillera Mountains.
The eastern part of the circuit is prone to land erosion owing to its slope (mountainous). The Municipality of San Gabriel has the highest susceptibility to soil erosion being a mountainous hilly municipality.
Flooding is the inundation of land areas which are not normally covered by water. It is usually caused by a temporary rise of the water level of a river, stream or other water course, inundating adjacent lands or flood-plains. This hazard can be brought about by heavy rainfall or sometimes dam or dike failure. The three types of flooding according to location are the river flooding, coastal and urban flooding while there are two types when it comes to duration, the flash flood (upstream floods) and the sheet flooding or what we called downstream flooding. The table below illustrates the flooding susceptibility of the circuit.
