Timeline: 2015-16 super El Nino gave India 86% of average rain; NOAA declared El Nino in June 2026, peak Oct-Dec

NOAA declared El Nino conditions in June and said the event could reach historic strength. India's 2026 monsoon was already deficient. Here is what the last super El Nino did, and what is still unknown for 2027.

Original report

Reporting as of 14 October 2026.

Will a super El Nino hit India in 2027? As of 14 October 2026 no 2027 monsoon forecast exists, but the US agency NOAA declared El Nino conditions in June and said the event was likely to strengthen to historic levels, Outlook India reported.

The last super El Nino, in 2015-16, left India with 86% of its average rainfall (Outlook India, 2026). It arrives after a weak year: India's 2026 monsoon was deficient, as we reported in Monsoon 2026 ends 12.6% short, India's driest season in 11 years.

A super El Nino is the strongest kind of event

"Super" is the label for a very strong El Nino, and 2015-16 was the last one, Outlook India reported. The exact threshold NOAA uses was not in the material we read, so we do not give one.

Ken Graham, director of the US National Weather Service, cautioned against assuming a repeat: "Every El Nino is not the same; each one is unique." Still, the last one is the clearest guide India has.

In 2015-16, India got 86% of its average rain

India received 86% of its average monsoon rainfall in 2015-16, Outlook India reported. IMD's long-period average is 868.6 mm (Down To Earth, 2026).

86% of 868.6 mm is about 747 mm, a shortfall of roughly 122 mm. That is our arithmetic on the two sourced figures, not an IMD statement.

Before this season, IMD had forecast below-normal rain at 90% of the long-period average, with a 60% chance of a deficient monsoon, Down To Earth reported. Farms feel any shortfall first.

Farms and reservoirs were already on watch

About 90% of India's pulses and oilseeds area is rainfed, Down To Earth reported. In June the government flagged 150-200 districts as high-risk and ordered contingency plans, the same report said.

Reservoir storage stood at 63.232 billion cubic metres on 14 May 2026, down 8 BCM in two weeks, according to Down To Earth. What comes next depends on forecasts not yet issued.

What we don't know yet about 2027

IMD has not issued its winter outlook or its 2027 monsoon forecast. NOAA's strong event is expected to peak between October and December 2026, Outlook India reported.

How long it lasts into 2027, and whether it overlaps the 2027 monsoon, is not settled in the sources we read. The next IMD outlooks are the dates to watch.

How we did this

We read Outlook India's report on NOAA's El Nino declaration and Down To Earth's report on the government's district contingency plans. We set the 2015-16 rainfall outcome against IMD's long-period average, did the arithmetic ourselves, and built the timeline in the chart.

The two outlets stressed different risks: Down To Earth the 200 districts and farm impact, Outlook India the chance of a record-hot 2027. We did not open NOAA's or IMD's own bulletins, so forecast details are as those outlets reported them.
