Region-by-region read from the latest NOAA numbers.
Peru & Ecuador coast
Risk 3/3Warm Pacific waters bring heavy rain
The coast of Peru and Ecuador tends to see torrential rain and floods when the Pacific is warmer than normal, a well-documented effect that historically hits this region the hardest during El Niño years.
Southern Brazil, Uruguay & NE Argentina
Risk 3/3Persistent heavy rain for southern Brazil
Southern Brazil, Uruguay, and northeastern Argentina often experience persistent, extreme rainfall due to a strengthened jet stream during El Niño years, as seen in recent major floods.
Amazon & Northeast Brazil
Risk 3/3Drought and fires likely in Amazon
The Amazon basin and Northeast Brazil tend to suffer severe drought, with record-low rivers, fires, and crop failures, as fewer rain-producing storms occur when the Pacific is warmer than normal.
Colombia & Venezuela
Risk 2/3Less rain for Colombia and Venezuela
Colombia and Venezuela often face below-normal rainfall, stressing hydropower and agriculture, with a higher risk of wildfires in Andean valleys during El Niño years.
Central America: Dry Corridor
Risk 3/3Dry Corridor faces crop failures
Central America's Dry Corridor tends to experience failed rains, threatening basic maize and bean harvests and increasing food insecurity when the Pacific is warmer than normal.
Indonesia & Malaysia
Risk 3/3Indonesia faces drought and fires
Indonesia and Malaysia often endure severe drought, leading to large forest fires and haze, with reduced rice and palm yields, a well-documented El Niño tendency.
Eastern Australia
Risk 3/3East Australia faces dry heat
Eastern Australia typically experiences reduced rainfall and heatwaves, increasing bushfire danger and straining water supplies along its populated east coast during El Niño years.
India & Pakistan: monsoon region
Risk 3/3Monsoon rains may weaken in India
India and Pakistan's monsoon region often sees weakened southwest monsoon rains, impacting agriculture and stressing water and power supplies when the Pacific is warmer than normal.
Philippines
Risk 3/3Philippines faces delayed rains
The Philippines tends to experience delayed rains and a harsher dry season, affecting rice production and hydropower, with water rationing common during El Niño years.
Southern United States
Risk 2/3Wetter winters for Southern US
The southern United States often sees wetter and stormier winters, particularly across California and the Gulf Coast, with increased flood and severe weather risks when the Pacific is warmer than normal.
Horn of Africa
Risk 3/3Flooding likely in Horn of Africa
Kenya, Somalia, and Ethiopia's lowlands in the Horn of Africa tend to experience heavier October-December rains, causing flooding and displacement, often following drought periods.
Southern Africa
Risk 3/3Summer rains fail in Southern Africa
Southern Africa, including the maize belt, often faces failing summer rains, leading to crop losses and power supply stress in countries like South Africa, Zimbabwe, Zambia, and Mozambique.
Northern & Central Mexico
Risk 2/3Drought and heat for Northern Mexico
Northern and Central Mexico tend to experience drought and heat during El Niño winters, stressing reservoirs, agriculture, and city water supplies.
Mainland Southeast Asia
Risk 3/3Mekong region faces drought impacts
Mainland Southeast Asia, particularly the Mekong basin, often suffers from droughts, leading to low river levels, saltwater intrusion, and pressure on rice crops and water supplies.
