What is monsoon onset?
Quick Answer
Monsoon onset is the beginning of the seasonal shift to a wet-weather pattern. It usually brings a major change in winds, clouds, and rainfall.
The Full Story
Monsoon onset is not just the first rainstorm of the season; it is the sustained transition into a monsoon circulation. In regions such as India, this shift is closely monitored because it affects agriculture, water supply, and public health. The timing can vary from year to year and is influenced by large-scale ocean-atmosphere conditions. Meteorologists look for a persistent change in wind direction, humidity, and rainfall distribution before declaring onset.
