This marks the start of the rainy season and provides relief from the hot and dry weather. The monsoon”s arrival over Kerala is a significant indicator of the seasonal transition across India.
Typically, the monsoon hits Kerala on June 1, but the date can vary by about seven days. The IMD has been forecasting the monsoon onset over Kerala since 2005 using a sophisticated statistical model.
