Mumbai saw heavy rain and thunderstorms on Monday as the southwest monsoon finally showed signs of life yet a massive 46% rainfall deficit means India is staring at one of its worst June droughts in over 100 years of weather records.

After nearly two weeks of stubborn inactivity, the southwest monsoon stirred back to life on Monday bringing with it heavy rain, thunder, and lightning to a rain-starved Mumbai. Moisture-laden winds began pushing into parts of Gujarat as well, offering the first real sign that India’s critical rainy season might finally be shifting gear.
Several parts of Mumbai woke up to moderate-to-heavy showers some areas recorded intense downpours within just a single hour. The rain brought welcome relief from the sweltering heat but also triggered waterlogging and significant traffic snarls across the city.
Mumbai Finally Gets a Break
Thundershowers lashed multiple city localities throughout the morning, sharply reducing visibility and slowing vehicles to a crawl at several intersections. Overcast skies and a cool breeze, however, made the morning feel genuinely refreshing after weeks of oppressive heat. Residents who stepped out found the city transformed roads glistening, air cooler, and the unmistakable smell of rain on hot tarmac filling the streets.
The southwest monsoon normally reaches Mumbai around June 10 each year. This time, it was markedly late it had advanced into south Konkan earlier this month, then simply stalled. Unfavourable atmospheric conditions blocked its further progress for days on end.
Monday’s heavy downpour immediately hit peak-hour traffic. The Western Express Highway already one of the city’s busiest arteries saw long jams following rain-related slowdowns. Waterlogging reports came in from multiple neighbourhoods. The weather office has issued a yellow alert running until Tuesday, with heavier spells predicted around Thursday and Friday as the system gains strength. A more significant intensification is expected around June 25 and 26. The southwest monsoon’s advance into more parts of Maharashtra is likely around June 23.
A Nation That Has Barely Seen Rain This June
But Mumbai’s showers, welcome as they are, cannot mask a deeply troubling picture unfolding across the rest of India. This June is on track to go down as the driest in more than a century and the numbers make for grim reading.
Between June 4 and June 22, the country received only 53.1 mm of rain, against a normal expectation of 97.6 mm. That translates to an overall rainfall deficit of 46 per cent. Vast belts of central, northern, and peninsular India remain parched falling squarely into the deficient and large-deficient categories on weather maps.
State-by-state data tells an even starker story. Maharashtra the very state where Mumbai sits has recorded a jaw-dropping shortfall of 85 per cent. Gujarat stands at 84 per cent below normal, making it among the worst-hit in the country. Madhya Pradesh, sitting at the heart of India’s monsoon belt, carries a 58 per cent deficit. Chhattisgarh and Jharkhand are both 71 per cent below normal. Meghalaya a state usually synonymous with some of the world’s heaviest rainfall has reported an 81 per cent deficit this June.
Satellite images released on June 22 help explain what went wrong. For several consecutive days, cloud formation stayed confined almost entirely to the Bay of Bengal, eastern India, and the Himalayan foothills. Central and western India sat under bare skies. Weak moisture flow and the absence of any organised monsoon systems stopped rain-bearing winds from pushing deep into the interior.
The Pattern Begins to Shift
Meteorologists say things are finally starting to change. Deep-layer moisture linked to the monsoon has begun arriving over Mumbai and nearby areas a promising development after weeks of dryness. Moist winds are also extending into south Gujarat, including the Surat region. Weather charts now show stronger moisture transport at mid-levels of the atmosphere an important technical signal that the Arabian Sea branch of the monsoon is rebuilding its momentum.
Rainfall activity is expected to pick up gradually over the next 24 to 48 hours across parts of Maharashtra, Gujarat, and central India.
Yet the recovery arrives after a damaging delay. Weather experts are now openly calling June 2026 one of the driest June periods in over 100 years of recorded climate data with deficits edging close to levels normally associated with major drought years. The weak monsoon has already disrupted kharif sowing schedules, intensified heat stress on both people and crops, and raised urgent concerns about water availability across several states. Farmers in Madhya Pradesh, Maharashtra, Gujarat, and Chhattisgarh have been waiting some anxiously, some desperately for consistent rain to start planting in earnest.
The coming days are critical. The monsoon has stirred but it now faces the enormous challenge of compensating for the massive deficit that piled up during the single most important phase of the entire season.
