Your weather app says the monsoon hits Kerala on May 26 this year. Six days early. Your group chat is already throwing umbrella memes and Mumbai-flooding GIFs. And by August, your grocery bill is going to tell you a very different story.
Because here’s the thing nobody on prime-time TV is bothering to explain properly: IMD is forecasting India’s first below-normal monsoon in 3 years — only 92% of the long-period average. The monsoon is arriving early AND bringing less rain. That sounds like a contradiction. It isn’t. And the reason is sitting in the Pacific Ocean, slowly cooking the price of every onion you’ll buy this year.
Early Monsoon, Less Rain — Wait, That Makes Zero Sense
Onset date and total rainfall are two completely different things. Meteorologists keep saying this and nobody hears it. The day the first monsoon cloud touches Kerala has almost no relationship with how much it’ll rain across the country over the next four months.
2025 proved it the optimistic way — monsoon arrived May 24, the earliest in 16 years, and India got above-normal rain. 2015 proved it the brutal way — monsoon arrived on schedule, then collapsed into one of the worst droughts in decades. The arrival is the trailer. The seasonal total is the actual movie. And the 2026 movie has a very specific villain.
The Pacific Ocean Just Cooked Your Onion Budget
That villain is El Nino — and forecasters are saying this one might be a Super El Nino, the rare extreme version.
In one sentence: the central Pacific Ocean gets unusually warm, that scrambles global wind patterns, and one of the side effects is that India’s monsoon weakens. That’s it. Sea temperatures 10,000 km away decide whether your sabzi-wala raises prices in July.
The last time we got a Super El Nino — 2015-16 — India received just 86% of normal rainfall. Reservoirs dried up. Vegetable prices spiked for months. IMD has now flagged 2026 as carrying India’s most dangerous monsoon probability in 25 years. That’s not a Twitter thread. That’s the official forecaster.
And 92% of LPA isn’t an abstract number. Roughly 75% of India’s annual rainfall comes in these four months. Nearly half the country’s workforce — 46% — works in agriculture. Sixty percent of farmers are completely dependent on the monsoon for the kharif crop, which is most of what lands in your kitchen between October and February.
Less rain → smaller harvest → higher prices. Wholesale inflation already hit 8.3% in April. Fertilizer prices are up 50% thanks to the Iran war disrupting global supply chains. The monsoon was supposed to be the one thing holding food inflation steady. It’s about to become the second domino.
Drought in Delhi, Floods in Chennai — Yes, Both. Same Monsoon.
Here’s the twist nobody saw coming. A weak monsoon doesn’t mean less rain everywhere. It means uneven rain. Some places get parched, some places get hammered.
LiveMint and India Today both have IMD’s risk maps. Punjab, Haryana, Delhi — drought-zone red. Chennai and parts of Tamil Nadu — flooding-zone red. Same monsoon. Opposite disasters. Your city could be facing water rationing in August while another city is wading through knee-deep streets the same week.
If you’re in northwest India, watch your municipal water alerts now, not in July. Bengaluru is already living the heatwave horror story, and reservoirs going into a weak monsoon is exactly how “Day Zero” headlines come back. If you’re down south, check your building’s drainage before June — the pre-monsoon storms that just killed 111 people in UP are the same atmospheric chaos that floods Chennai when it switches direction.
The Bottom Line
An early monsoon is the kind of headline that feels like good news. It isn’t. It’s the trailer for a season IMD itself is calling the most concerning in a quarter-century — driven by a Pacific Ocean event nobody on this continent can control, layered onto an economy already taking hits on petrol prices and import-dependent goods.
The forecast you should actually care about isn’t the May 26 onset date. It’s the August grocery bill, the September water tanker rate, and whether your state ends up on the drought map or the flood one.
Either way, the early monsoon isn’t doing you a favour. It’s just giving you a slightly earlier warning.
