Summer Monsoon / Pre-monsoon Season (March-May)
During this period, a low-pressure area gradually replaces the high-pressure system. Seasonal cyclonic winds gain strength. By May and June, northwestern India and Pakistan experience high solar radiation, leading to a thermal high and warm air rising, resulting in a low-pressure region known as the thermally produced low-pressure zone.
Northwestern India records the highest temperatures, with midday temperatures in Rajasthan ranging from 40°C to 50°C. Peninsular India experiences significantly cooler temperatures compared to northern India. Heatwaves are widespread in the northern and central regions, while northwestern India remains hot and dry.
Despite the arid climate, intense convection can trigger thunderstorms in states like Rajasthan, Punjab, Haryana, and Uttar Pradesh. Evening thunderstorms are common in Assam, West Bengal, and Bihar. These severe thunderstorms, known as “andhis,” appear to originate from the northwest.
The Indian Peninsula receives rainfall due to the convergence of inter-tropical and equatorial westerlies heading northward. Pre-monsoon showers hit Kerala and the western coast, marking the beginning of the Indian monsoon season, usually in late May or early June along the Kerala coast.
