El Niño is forming, the monsoon has arrived, and the headlines are loud. The only question worth asking as an investor: is this a 2015-style problem, or noise? Too early to call — but we can read the scorecard as it stands.
The four dials
The forecast itself barely moved — but the odds of a poor season nearly doubled (deficient-season odds rose from 35% to 60% between April and June).
- IMD monsoon forecast: 90% of LPA. Below 96% is "below normal"; below 90% is "deficient". The lowest official call in three years — a caution flag, not an alarm.
- Deficient-season odds: 60%. Up from 35% in April as the El Niño signal firmed.
- Reservoir storage: ~34%. Down to about a third by late May and still drawing down. The tank is not full; it needs this monsoon to refill.
- Inflation cushion: ~4%. Near the RBI's target — far from crisis — but ticking up on vegetables, fuel and a weaker rupee.
Read together: a below-normal season is the base case, and the shock absorbers are only partly charged.
What the rains have done
The monsoon reached Kerala on 4 June — three days late — then advanced briskly across the northeast and peninsula. But the timing is the part most people miss: *El Niño years tend to suppress the back half of the monsoon.* June–July can look fine on leftover atmospheric moisture; August and September are the real test, and September is when standing kharif crops are most exposed, right before harvest.
The buffers, only partly charged
The reassuring version says India has full reservoirs and low inflation. The accurate version is more mixed:
- Mumbai's supply lakes: ~13.6% — a 10% supply cut has run since mid-May; one of the seven lakes already empty.
- Krishna basin: ~22% — among the lowest of the large peninsular basins.
- Godavari basin: ~41% — near the national average, not above it.
- All-India (166 reservoirs): ~34% — down from ~39% at end-April, still falling.
Across Maharashtra, 700-plus water tankers were running across ~15 districts through May, with Marathwada among the hardest hit. Much of the northern kharif heartland — which leans on already over-drawn groundwater — was still outside the monsoon's reach by mid-June. Inflation, the more real buffer, was 3.48% headline in April (food 4.20%) and tracking near 4% in May — close to target, but rising, not easing.
The missing counterbalance
In 1997 a super El Niño hit, yet India's monsoon finished near normal — rescued by a positive Indian Ocean Dipole, the Indian Ocean's own see-saw that pulls moisture back toward India. The catch for 2026: the IMD expects the Dipole to stay neutral through the season, developing positive only near the very end — too late to help the crucial Aug–Sept window. The 1997-style rescue is largely off the table. That's the single most important nuance in this year's outlook.
The bottom line, today
The monsoon has started steadily but late, the official forecast leans below normal, the odds of a deficient season have risen, reservoirs are low, and the inflation cushion is real but thinning. None of that is a crisis — and none is "all clear" either. The most useful thing to hold in your head is the calendar: June and July tell you little; August and September tell you almost everything. Until then, the right posture is informed patience.
