Minimal impact · 3/10 Weak signal in El Niño years
What changed since 9 Oct 2026

Score moved 2 → 3 . “A rare "Godzilla" El Niño is rewriting South Asia's monsoon script — and Bhutan's farmers are watching the sky”

A rare, record-strength El Niño has formed, with global coverage warning of "Godzilla strength" conditions and South Asia expected to receive below-average monsoon rainfall. Yet measured conditions in Bhutan for 9 July–6 October 2026 show rainfall about 25% above the 1991–2020 normal and mean temperatures about 0.9°C above normal, a reminder that El Niño's canonical signal for Bhutan is weak. The Kharif calendar stayed broadly on schedule, but fishers and farmers remain exposed to fuel-cost pressures and any late-season shift in the monsoon as the event peaks.

SIGNAL CHECK
On schedule

Kharif planting and the June–September monsoon proceeded broadly on schedule, with the October–November harvest and subsequent Rabi season likely to be shaped by how quickly El Niño conditions decay.

Sector by sector

Agriculture

Kharif planting and harvest are on schedule, but a below-average monsoon forecast for South Asia keeps late-season crop and pasture risk elevated.

Water & flooding

Above-normal rainfall has eased immediate water stress, though a strong El Niño could still bring erratic dry spells during the Rabi season.

Health

Warmer-than-normal conditions (+0.9°C) raise the risk of heat stress and vector-borne disease expansion, with nutrition security tied to the monsoon outcome.

Energy

Hydropower generation benefits from above-normal inflows, but a drying trend later in the season could reduce reservoir recharge.

Fisheries

Fishers face compounding pressure from a looming El Niño and a fuel crisis that raises the cost of every trip, as reported by Dialogue Earth.
