We're headed for an El Niño that is — quite literally — off the charts.
WMO's Global Seasonal Climate Update shows that El Niño is forecast to exceed the scale of global monitoring charts. Its impacts will be felt well into 2027.

El Niño is set to hit fragile communities hard.
@UNOCHA and @WMO are sounding the alarm, appealing for immediate assistance to support communities already affected by what has been described as the strongest El Niño on record.
news.un.org/en/story/2026/10…
El Niño is back, and it is more powerful than ever.
We must act urgently to limit the impact.
With @WMO, we have set out the potential impact. And called for action.
Join @WMO Secretary-General Celeste Saulo and @UNOCHA@UNReliefChief today as they call for early action as an unprecedented El Niño is set to hit fragile communities hard.

The total amount of water stored in groundwater, lakes and rivers, soil moisture, vegetation and ice and snow – has been in decline since mid-2010s.
Read the WMO #StateOfWater Report 2025 to learn about what this means for the water we depend on. bit.ly/WMOStateofWater2025Re…

Areas in blue depict above-normal storage, while orange indicates below-normal storage. The World Meteorological Organization (WMO) logo is in the corner. "#StateOfWater 2025" is at the bottom.
Grenada becomes the latest Member of the World Meteorological Organization, having deposited its instrument of accession to the WMO Convention.
WMO now has 194 Members: 188 Member States & 6 Member Territories.
Congratulations & welcome to the WMO family!

Swiss glaciers lost 5% of their ice in 2026, accdg to GLAMOS. Their total volume has shrunk by nearly 20% in the last 5 years.
This echoes the WMO’s #StateOfWater 2025 report, which found that every glaciated region on Earth lost ice in the last 5 years.

El Niño was first observed by Peruvian fishermen, who noticed that unusually warm coastal waters sometimes appeared and reduced their catches.
Beyond the Pacific, El Niño can affect the food that reaches our plates. Its impacts vary across regions. Read: bit.ly/4ymTbM4
As El Niño strengthens, above-normal temperatures are forecast across much of the world, threatening food systems.
Extreme heat can reduce fish catches and crop yields, stress livestock and endanger farmers’ health.

ALT This image is a global seasonal climate update for October to December 2026. It features two maps: one titled "Temperature Forecast" and the other "Rainfall Forecast." Both maps display color-coded regions indicating areas of below normal, normal, and above normal conditions. The bottom note states the forecast is probabilistic and issued in September 2026. The logo of the World Meteorological Organization (WMO) is present.
Today more than 120 countries have multi-hazard early warning systems, a big leap from ~50 countries a decade ago. But many are still unprotected. #EarlyWarningsForAll is not a luxury. It saves lives, reduces economic losses, & provides tenfold return on investment.

Sea-surface temperature anomalies across central-eastern equatorial Pacific, where El Niño develops, is forecast to reach 3.7°C above normal for the Oct-Dec 2026 season.
Set to be the highest on record and stronger than the previous record in late 2015.

Isaias has become the 1st hurricane of an exceptionally quiet Atlantic season.
@NOAA@NHC_Atlantic says Isaias is strengthening & expected to approach northern US Gulf Coast as a “dangerous hurricane” on Friday. Storm surge & hurricane warnings in effect.
