We are in the transition phase now wherein winters are over and pre-monsoon activities are about to set in. Although, parts of Central India and Northwest India have witnessed pre monsoon activities during the first week of March, but these rain and thunder showers cannot be termed as typical pre-monsoon activities. This is because these activities were not accompanied by strong winds and heavy thunderstorm.
During the transition phase, weather of the entire country usually goes dry as the Western Disturbances starts weakening and moving in upper latitudes. Their impact also starts reducing over northern plains leading to dry weather over the hills as well as the plains of North India.
The Bay of Bengal as well as Arabian Sea remain usually calm during March. Although, five cyclones have formed over Bay of Bengal in the month of March but these cyclones have formed in a span of 121 years.
Pre monsoon activities commence by late March or early April when temperatures of Northwest India start breaching the 40-degree mark. That is why weather activities take a break between late February and late March.
