Monsoon Loses Momentum Midway Through June
As June reaches its midpoint, a worrying and unusual picture has emerged regarding the southwest monsoon, often described as India’s lifeline. According to the latest satellite imagery and weather data, the monsoon has weakened significantly across large parts of the country, leading to a sharp decline in rainfall activity.
Satellite images show an absence of the widespread cloud cover typically associated with an active monsoon. Vast stretches of central, eastern, and peninsular India appear unusually dry, raising concerns among meteorologists and farmers alike.
Rainfall Deficit Touches 64 Percent
Data released by the India Meteorological Department (IMD) for the period between June 4 and June 15 paints a concerning picture. During this period, India received only 19.2 mm of rainfall against the normal average of 53.7 mm.
This translates into a rainfall deficit of nearly 64 percent, significantly below seasonal expectations. The deficit has heightened fears over water availability and the timely sowing of kharif crops, which heavily depend on monsoon rains.
IMD maps indicate large parts of central, southern, and eastern India under severe rainfall deficiency, with many regions witnessing conditions resembling an early-season drought.
Satellite Images Reveal Unusual Monsoon Pattern
One of the most striking indicators of the monsoon slowdown comes from images captured by the INSAT-3DS satellite on June 15. Normally, weather maps during this period are covered with dense cloud formations associated with active monsoon systems.
However, the latest images show extensive clear skies over central and peninsular India, highlighting the abrupt weakening of monsoon activity.
Meteorologists say the lack of cloud formation is not due to a shortage of moisture over the surrounding seas but because of atmospheric conditions preventing rain-bearing systems from developing.
Battle of Winds Behind the Monsoon Slowdown
Weather experts attribute the current situation to an unusual interaction of upper-level wind systems in the atmosphere.
The Westerly Jet Stream, which typically remains farther north, has shifted significantly southward. This has interfered with the Easterly Jet Stream, considered one of the key drivers of monsoon circulation over India.
Under normal conditions, easterly winds help lift moist air upward, leading to cloud formation and rainfall. However, the stronger-than-usual westerly winds are suppressing this process, effectively blocking the monsoon’s progress.
As a result, despite abundant moisture over the Arabian Sea and the Bay of Bengal, the water vapour is unable to convert into widespread rainfall over the Indian mainland.
Impact on Agriculture and Water Resources
The prolonged dry spell has triggered concerns among farmers, especially in regions dependent on timely monsoon rains for kharif sowing. Delayed rainfall could affect crop planting schedules and put additional pressure on reservoirs and groundwater resources.
Agricultural experts are closely monitoring the situation, as the coming weeks will be crucial for crop establishment in several states.
Relief Likely by End of June
Despite the current setback, meteorologists say the situation is unlikely to persist for long. Forecasts suggest that the Westerly Jet Stream is expected to weaken gradually later this week.
Once this atmospheric barrier eases, monsoon circulation is likely to regain strength. Weather models indicate that rainfall activity could revive significantly during the last week of June, bringing a fresh spell of widespread showers across many parts of the country.
Monsoon Pause May Soon End
Experts describe the current phase as a temporary “monsoon pause” rather than a complete failure of the season. With favourable conditions expected to return in the coming days, hopes remain high that the monsoon will regain momentum and help bridge the rainfall deficit.
Until then, farmers, water managers, and millions of Indians will be closely watching the skies, waiting for the monsoon’s second innings to begin.
