Bay of Bengal Systems May Revive India’s Monsoon Activity
Weather scientists are watching the Bay of Bengal for new low-pressure systems.
These systems can help create rain when they move over land.
Several may travel toward central India in the next five to seven days.
They could bring more rain to eastern and central parts of India.
Some areas need this rain because their monsoon rainfall is below normal.
Early September may be very important for the final monsoon result.
India has received less rain than usual overall this season.
However, some places have received much more rain, while others have received much less.
Several low-pressure systems may form over the Bay of Bengal and move toward central India within five to seven days.
The systems could bring widespread rain to eastern and central India, including areas facing monsoon deficits.
Early September is expected to be crucial for determining the Southwest Monsoon’s final seasonal performance.
India has received 587.8 millimetres of rain against a normal 679.5 millimetres, a 13 per cent deficit.
Rainfall remains uneven, with Ladakh 204 per cent above normal while Meghalaya is 58 per cent below normal.

- When
- The systems are expected over the next five to seven days, with early September considered especially important.
- Where
- The systems are expected to form near the Bay of Bengal and move toward central India, affecting eastern and central regions.
- Why
- Their rainfall could reduce regional deficits and influence the final performance of the 2026 monsoon season.
- Current national rainfall
- India has received 587.8 millimetres against a normal 679.5 millimetres.
- Overall seasonal status

- Expected weather systems
- Several low-pressure systems may form and move westward toward central India within five to seven days.
- Critical period
- The first half of September could significantly influence the season’s final rainfall totals.
- Potential seasonal swing
- Final monsoon rainfall could vary by about 5 per cent above or below current levels, depending on activity.
