World Meteorological Organization urges people to prepare for El Niño
On Tuesday, June 2, 2026, the World Meteorological Organization (WMO), based in Geneva, Switzerland, urged people to prepare for coming El Niño conditions. The WMO, a specialized agency of the United Nations that focuses on weather, climate and water resources, said:
Fueled by unusually warm ocean waters in the tropical Pacific, El Niño conditions are developing and are set to influence global temperature and rainfall patterns, increasing the risk of extreme weather over the coming months.
The newest update on El Niño conditions now shows an 80% likelihood of El Nino developing in the next three months. Plus, the likelihood that El Niño conditions will continue until at least November are around 90%. And there is still a possibility that it will become a super El Niño event.
UN Secretary-General António Guterres did not hold back in a statement:
The science is clear: El Niño is arriving on our doorstep in the coming months with 90% certainty. The world must treat it as the urgent climate warning it is. El Niño conditions will pour fuel on the fire of a warming world. Impacts will hit even harder, travel even farther, and cross borders with devastating speed. The only effective response is climate action equal to the crisis – ending the addiction to fossil fuels, accelerating the shift to renewables, protecting the most vulnerable, and delivering early warning systems for all.
What could El Niño bring?
WMO Secretary-General Celeste Saulo said:
We need to prepare for a potentially strong El Niño event – which will exacerbate drought and heavy rainfall and increase the risk of heatwaves both on land and in the ocean. The most recent El Niño, in 2023-24, was one of the five strongest on record and it played a role in the record global temperatures we saw in 2024.
Just like any weather event, preparation is key. The WMO said that nearly everywhere can expect above average temperatures for June to August. Do you know how to beat the heat? Meteorologist Rachel Duensing provides tips below.
Celeste Saulo also said:
Advance seasonal forecasts and early warnings are vital to save lives and cushion the impact on our economies and our communities.

What is a super El Niño?
So what is an El Niño and a super El Niño? Let’s start with what a typical El Niño is. There are three types of conditions that can guide global weather: El Niño, La Niña and neutral. These three conditions make up ENSO, or the El Niño–Southern Oscillation. ENSO is a natural climate pattern in the tropical Pacific Ocean that shifts between warm and cool phases. El Niño is the warm phase and La Niña is the cool phase. And these phases influence weather around the world, including rainfall, droughts and storms.
So an average El Niño occurs when warm water pools up in the eastern Pacific Ocean, around the equator. Once the temperatures reach 0.5 degrees Celsius (0.9 F) warmer than normal in the sea surface, an El Niño has formed. El Niño conditions can last for up to a year.
A super El Niño is a stronger event. Meteorologists often call it a super El Niño when the sea surface temperature anomalies peak at about 2.0° C (3.6 F) above normal. And currently, some models are calling for the coming El Niño to exceed 2.5° C (4.5 F) above the seasonal average by October.
You can follow along with NOAA’s El Niño watch here. The next update will be on June 11. As of May 16, 2026, NOAA said:
El Niño is likely to emerge soon (82% chance in May-July 2026) and continue through Northern Hemisphere winter 2026-27 (96% chance in December 2026-February 2027).
Higher temperatures with El Niño
An El Niño usually brings higher global temperatures. The excess heat in the Pacific Ocean eventually enters the atmosphere. This causes warmer global temperatures. However, the rise in temperatures often has a lag time of a few months.
Some forecasters have already said that if a strong El Niño emerges, 2027 could become one of the hottest years on record. Northern Illinois University meteorology professor Victor Gensini told PBS:
A strong El Niño could plausibly push global temperatures to new record levels in late 2026 and into 2027.
This comes on the heels of the hottest March on record for the contiguous United States. NOAA said:
The contiguous U.S. average temperature in March was 50.85° F (10.4 C), 9.35° F (5.19 C) above the 20th-century average, marking the first time any month’s average has exceeded 9° F (5 C) above that baseline.
Other impacts from El Niño
In the summer, El Niño can dampen hurricane formation in the Atlantic. But it’s in winter that we feel El Niño the strongest. Often the jet stream will drop south, steering storms into California and Arizona and bringing much-needed rain. If the jet stream drops, then the southern and eastern U.S. can expect wetter and cooler weather. Meanwhile, drier weather could prevail in the northern U.S. and Great Lakes region.
Across the globe, El Niño brings drought conditions to places such as Australia, India and central Africa. And it can bring heavy rains to southern South America and eastern Africa.
Staying safe in extreme heat
From EarthSky’s weather author, meteorologist Rachel Duensing:
Staying safe in extreme heat can vary a bit depending on your situation. But the main idea is to avoid the heat as much as possible. If you are able to stay inside, ideally in air-conditioning (A/C), this is your best option. But as mentioned, if you cannot avoid the hot weather, there are things you can do. Take frequent breaks in the shade. Make sure you’re staying hydrated. Wear light color, loose-fitting clothing. And pay close attention to how you’re feeling as the day goes on.
If you, or someone you are with, is sweating heavily, feeling weak, tired, dizzy or nauseated, these could be signs of heat exhaustion. Immediately move yourself or the other person into A/C. Loosen their clothing, give them sips of cool water and put cold compresses on their body.
If someone is acting confused and slurring their speech, has red and hot skin or passes out, this is likely a heat stroke. They need medical attention immediately! Call 911. While you wait for help to arrive, move the person to A/C, add cool compresses to lower their body temperature, but do not give them anything to drink.
The heat can also be more dangerous to the very young, the very old, people with chronic medical conditions and pregnant women. In addition, the unhoused and lower income communities, who may not be able to afford to run their air-conditioning, are also at risk. Check on your friends, family and neighbors before, during and after extreme heat.
Bottom line: The World Meteorological Organization said on Tuesday, June 2, 2026, that people should start preparing now for above average temperatures and extreme weather due to coming El Niño conditions.
