The India monsoon 2026 onset actual progress is ten days old now, and the early numbers are doing something the IMD’s April model didn’t quite predict. The forecast called for 92% of normal — below normal, below trend, with a margin of error too thin to ignore.
Where the Rain Has Actually Reached
IMD’s June 9 advisory tracked the southwest monsoon into the remaining northeastern states, all of Sikkim, and parts of Sub-Himalayan West Bengal — roughly on the normal pace. Then on June 10, a western disturbance started dumping unseasonal rain across Punjab, Haryana, and Delhi, with the wet spell expected to continue till June 13 — weeks before the monsoon would normally arrive there. It fits a broader India’s extreme weather pattern that’s been intensifying through the pre-monsoon weeks.
That’s not a strong monsoon. It’s not a weak one either. It’s a wet northwest India in early June, which the April forecast didn’t account for.
What the 92% Number Actually Means
The April seasonal forecast pegged this monsoon at 92% LPA — roughly 800mm against the 50-year average of 870mm. The categorisation is unforgiving: below 96% is officially “below normal,” below 90% is “deficient.” The model carries a ±5% error band, which means actual rainfall could land anywhere between 87% and 97%.
IMD has been issuing these forecasts since 1886. The April number is the first cut. The updated forecast usually lands in late May with regional granularity — and ten days of post-onset data won’t confirm or break it.
Kharif Sowing 2026: The Decision Farmers Are Making This Week
Kharif sowing begins with monsoon onset. Rice, cotton, pulses, oilseeds — all of it planted on what the soil holds this week, not what a model predicted in April. Compounding the pressure: a fertilizer shortage colliding with kharif season, which means even farmers with adequate soil moisture may face input gaps. Farmers don’t plant on forecasts. They plant on neighbours, soil moisture, and the rain they can see.
A monsoon that delivers 92% evenly is workable. One that drops 110% in Assam and 60% in central India breaks rural balance sheets — and shows up as food inflation 90 days later.
Ten days in, the below-normal forecast is still on the books. The actuals are inconclusive — but unusually skewed northwest. India kharif sowing is underway regardless. Farmers are planting on what they see, not what the model said. The forecast can be wrong. The planting window can’t.
