When Will Monsoon Reach Mumbai? IMD Predicts Rainfall From Next Week; Yellow Alert Issued for Thane, Raigad

Mumbai's long wait for the monsoon may finally come to an end next week as weather conditions turn favourable for the advancement of the southwest monsoon over the Konkan coast.

After weeks of intense humidity, rising temperatures and a significant rainfall deficit, the India Meteorological Department (IMD) has predicted an increase in rain activity across Mumbai and nearby districts from June 22 onwards, bringing much-needed relief to residents and easing concerns over falling water reserves.

Mumbai Weather Prediction: When Will Monsoon Reach Mumbai? IMD Issues Fresh Weather Update

Although Mumbai's normal monsoon onset date is June 11, the rain-bearing system has remained stalled and failed to make its expected progress over the region. The delayed arrival has resulted in an unusually dry June, with residents experiencing prolonged spells of heat and discomfort.

Mumbai Rain Update: Monsoon Likely to Advance Over Konkan by June 24

However, the IMD has indicated that atmospheric conditions are becoming favourable for the southwest monsoon to advance into the Konkan belt around June 24. Before its full arrival, Mumbai is expected to witness a gradual increase in rainfall intensity beginning June 22.

IMD Issues Yellow Alert for Mumbai, Thane, Palghar and Raigad Till 22-23 June

The weather department has issued a yellow alert for Mumbai and surrounding districts, including Thane, Palghar and Raigad, for June 22 and June 23.

During this period, the city is likely to receive light to moderate rainfall accompanied by thunderstorms, lightning and gusty winds reaching speeds of 30-40 kmph at isolated locations. The rainfall activity is expected to become more widespread over the next few days as the monsoon system strengthens over the western coast.

Mumbai Lakes Under Pressure as Water Stock Falls to Just 9%

While the expected rainfall offers relief, the delay in the monsoon has already put Mumbai's water security under stress. The city depends on seven major lakes for its daily drinking water supply, and the combined water stock has dropped to only around 9 percent of total capacity, equivalent to nearly 1.30 lakh million litres.

The situation is significantly weaker compared with the same period last year, when lake storage levels were around 25 percent of their capacity, highlighting the impact of the delayed and weak monsoon so far.

Mumbai Water Cut Continues for Next Few Weeks

The declining lake levels have already led to water conservation measures in the city. However, civic authorities have stated that the available lake storage, along with reserve water support from the state government and demand-management steps, should be sufficient to meet Mumbai's needs until around mid-August.

This provides temporary relief from an immediate water crisis, but the coming weeks remain crucial. Consistent monsoon rainfall over Mumbai's catchment areas will be necessary to replenish reservoirs and improve the city's water situation.
