While September does see many rainy days, it is October that sees the ominous black clouds blown over by the winds of the Northeast Monsoon. What is usually forecast as thundery showers is more realistically intense electrical storms accompanied by torrential downpours. The weather pattern can sometimes be predictable for a period of days, raining once or twice every day at the same time every day for a short duration with sunny periods between. Otherwise, if the clouds remain it could rain any time.
