El Niño impacts around the world
A strong El Niño rearranges rainfall and temperature on every continent — some regions flood while others burn. Pick a region on the map or browse the guides below for the historical record and the 2026–27 outlook.
Argentina
One of the few countries where El Niño is usually good news — until the rain arrives at harvest.
Atlantic Basin
The one El Niño impact that arrives before winter: shear-suppressed Atlantic activity — with the 'it only takes one' asterisk written in 1992.
Australia
Dry east, primed fuels, a wheat belt on edge — Australia faces the sharpest downside of a strong El Niño winter and spring.
Brazil
One country, two opposite signals: drought in the north and northeast, flooding rain in the south. Coffee sits on the wrong side of it.
California
California's wettest winters cluster in strong El Niño years — and 2026–27 is forecast to be one of them.
Colombia
Dry season deepens, reservoirs fall, and the world's biggest washed-arabica crop takes the strain.
East Africa
The October–December short rains arrive loaded: flood and outbreak risk for a region still recovering from its longest drought in decades.
Europe
The teleconnection is faint and fickle — but the coffee in your cup and the reinsurance on your books are exposed all the same.
US Gulf Coast & Southeast
The subtropical jet parks overhead: more rain, cooler days, and the one El Niño hazard the Southeast underestimates — winter tornadoes.
India
A billion-person economy runs on four months of rain — and El Niño historically loads those months toward deficit. With famous exceptions.
Indonesia
The archipelago sits under El Niño's departing rains — drought, peat fires and regional haze are the historical price of a strong event.
US Northeast & Midwest
The mildest-leaning region of the El Niño map — and the one where a single storm can rewrite the season's story in a weekend.
Pacific Basin
The Atlantic gets quieter in an El Niño. The Pacific does something more interesting: the same storms form somewhere else, and arrive different.
US Pacific Northwest
The storm track goes south, the mountains stay warm, and the snowpack pays for it — with consequences that last into next summer's rivers.
Philippines
Dry dams, water rationing and a rice crop under pressure — but fewer typhoons making landfall. The Philippine El Niño is a trade, not a straight loss.
South Africa
The clearest El Niño drought signal in the southern hemisphere, aimed straight at the maize belt.
Peru & South America
The place that named El Niño still takes its hardest punch: coastal floods, a collapsing fishery — and a wetter windfall far to the south.
Southeast Asia
From the Mekong Delta's salt lines to Manila's water taps, a strong El Niño squeezes the region that feeds the world its rice.
United States
El Niño loads the dice for a wet, stormy South and a milder North — and 2026–27 is forecast to be a strong to very strong event.
Vietnam
Drought in the Central Highlands hits the world's robusta supply; salt pushes up the Mekong Delta behind it.
What often gets mixed up
El Niño shifts the odds by region and by season — it does not do one thing everywhere. Six claims that travel well and read wrong, each checked against its source.
Often said: El Niño brings more Atlantic hurricanes.
Actually: It tends to suppress them: stronger upper-level westerlies raise the vertical wind shear over the tropical Atlantic, which tears developing storms apart or stops them forming.

Often said: El Niño means drought across the southern United States.
Actually: The typical winter is the opposite: an exceptionally stormy season with more precipitation than normal across California and the southern U.S.
Winter, December–February · NOAA Climate Prediction Center — North American winter features
Often said: El Niño makes every U.S. winter warmer.
Actually: Only the northern states tend to be milder than normal. Along the Gulf Coast, winters tend to run cooler than normal.

Often said: El Niño dries out South America.
Actually: Not its southeast: southern Brazil and central Argentina tend to be wetter than normal — the opposite of a continent-wide drought.

Often said: El Niño does the same thing to all of Africa.
Actually: It pulls the continent in two directions: southern Africa tends to be drier in its main rainy season, while equatorial eastern Africa tends to be wetter.

Often said: El Niño guarantees floods in East Africa.
Actually: It frequently enhances the "short rains", but local drivers and the Indian Ocean Dipole matter too, so the effect varies from year to year. The widespread flooding of 1997 came when El Niño and a positive Dipole were in place together.

Events whose own source names El Niño. We quote the source and link to it; we do not summarise it and we do not attribute anything El Niño was not blamed for by the people reporting it.
