We're headed for an El Niño that is — quite literally — off the charts.

The latest WMO Global Seasonal Climate Update shows that El Niño is forecast to exceed the scale of global monitoring charts used over the past four decades. Its impacts will be felt well into 2027.

As El Niño intensifies and fuels more extreme weather, it could compound humanitarian needs, particularly among refugees, conflict-affected communities, displaced people and other vulnerable populations.

WMO and United Nations OCHA are calling for early action to save lives and livelihoods, especially fragile communities.

WMO Secretary-General Celeste Saulo and United Nations OCHA Humanitarian Chief Tom Fletcher call for urgent humanitarian action as the unprecedented El Niño is set to hit fragile communities hard.

Extreme weather events are expected to multiply as El Niño intensifies.

Already vulnerable populations such as refugees, communities living in conflict, and displaced populations where housing, water, sanitation and health services are already under pressure, are at greater risk.

The new WMO Global Seasonal Climate Update, released today, indicates that El Niño is forecast to peak towards December 2026.

But extreme weather does not need to turn into a humanitarian emergency. WMO is working closely with UNOCHA and partners across the United Nations and the humanitarian community to turn climate forecasts into practical decisions that protect lives and livelihoods.

𝐓𝐡𝐞 𝐥𝐚𝐭𝐞𝐬𝐭 𝐖𝐌𝐎 𝐆𝐥𝐨𝐛𝐚𝐥 𝐒𝐞𝐚𝐬𝐨𝐧𝐚𝐥 𝐂𝐥𝐢𝐦𝐚𝐭𝐞 𝐎𝐮𝐭𝐥𝐨𝐨𝐤 𝐟𝐨𝐫𝐞𝐜𝐚𝐬𝐭𝐬:

📍 East Africa: Wetter-than-normal conditions are more likely in parts of the region during the October–December rainy season, increasing concerns about heavy rainfall and flooding.

📍 Southern Africa: Increased risks of drier conditions that could affect crop production, water availability and livelihoods from November, the typical start of the rainy season.

📍 Southeast Asia: Warmer conditions and rainfall deficits increase the risk of heat exposure and place additional pressure on agriculture and water supplies.

📍 The Americas: increased rainfall in Northwest US and southern parts of western South America. North America and the northern portion of the Caribbean is also expected to face above normal precipitation. Increased drought risk is likely in parts of Central America, the southern Caribbean and the Amazon.

Behind the application of weather, climate and water services is a technical commission that supports their consistent and reliable development and delivery worldwide.

The Commission for Weather, Climate, Hydrological, Marine, and Related Environmental Services and Applications (SERCOM) is meeting at WMO this week to continue supporting the implementation of the WMO Strategic Plan by developing and implementing globally harmonized services and applications.

Discussions between WMO Members and technical experts will include early warnings, flood forecasting, storm surges and aviation safety among others.

Welcome to the WMO family, Grenada 🇬🇩!

Grenada becomes the latest Member of the World Meteorological Organization (WMO), having deposited its instrument of accession to the WMO Convention on 18 October 2026.
The new addition brings WMO’s membership to 194: 188 Member States and 6 Member Territories.

Grenada, which consists of several small islands, is vulnerable to impacts of severe weather and the changing climate. In 2024, Grenada suffered widespread devastation and disruption when it was hit by a strong Hurricane Beryl.

What does it mean to be a member of the WMO?

Grenada will be integrated into WMO’s Regional Association for North America, Central America and the Caribbean (RAIV) and the RAIV Hurricane Committee. It will have access to WMO’s full range of services to improve forecasts and early warnings, strengthen its observing network and develop institutional and technical capacity.

Congratulations!

This pole below measures how much ice the Great Aletsch Glacier in Switzerland lost during the summer of 2026. Almost 6 meters of ice.

A winter with little snow, followed by prolonged and intense heatwaves from May to September, has left Switzerland's glaciers facing an exceptional year of ice loss.

Data from the Glacier Monitoring Switzerland (GLAMOS) show that 5% of the remaining ice on Swiss glaciers have melted in 2026. That means that the mean thickness of individual glaciers fell between 2.5 to 4 metres.

In the past five years, the volume of ice in Switzerland has already fallen by almost 20%.

These findings echo the WMO’s 2025 report, which found that every glaciated region on Earth had lost ice for the last four years.

Essential Climate Variables provide the critical evidence we need to understand Earth's climate, track how it is changing, improve climate predictions and support informed climate action.

This month, we're looking at 𝐬𝐞𝐚-𝐬𝐮𝐫𝐟𝐚𝐜𝐞 𝐭𝐞𝐦𝐩𝐞𝐫𝐚𝐭𝐮𝐫𝐞!

Swipe to discover what it means, why it matters, how it is measured, and what rising ocean temperatures tell us about our changing climate.

Understanding and monitoring Essential Climate Variables relies on a strong global climate data ecosystem. Together with the Global Climate Observing System and Group on Earth Observations, we are working to strengthen climate information and help communities, governments and businesses make better-informed decisions.

Did you know that El Niño was first observed by Peruvian fishermen, who noticed that unusually warm coastal waters sometimes appeared and reduced their fish catches?

Beyond the Pacific, El Niño can affect the food that reaches our plates in more ways than we might realize.

From South America to the Greater Horn of Africa and South Asia, discover how El Niño’s impacts on food systems vary across and within regions.

🌡️ Above average temperatures are very likely during the October-December 2026 season in most land areas worldwide, according to the latest WMO Global Seasonal Climate Update.

This prediction indicates a strong signal that heat extremes and heat-related impacts are likely during the season. It does not mean every location will be warmer than average every day.

The WMO update also forecasts large and coherent shifts in rainfall patterns that are consistent with a strong El Niño event.

☔️ Above-normal rainfall is predicted across the central and eastern equatorial Pacific east of the Date Line. Wetter-than-normal conditions are also more likely across the Greater Horn of Africa; parts of Central Asia and coastal East Asia; northern parts of the Arabian Peninsula; parts of North America south of 45°N; and southeastern South America.

☀️ Meanwhile, a broad dry signal is forecast over both the western Pacific and the equatorial Atlantic Ocean, stretching across the South Pacific to the southern tip of South America. Drier-than-normal conditions are forecast over the Indian subcontinent; southern Central America and parts of the Caribbean; northwestern South America.

Friendly reminder: These signals describe where wetter- or drier-than-normal seasonal conditions are more likely, but they are not a substitute for national and local forecasts!

Take note: Colours in these maps represent forecast probability, not temperature or rainfall magnitude.
