For the June-July-August 2026 season, WMO forecasts indicate significant shifts in rainfall patterns—a classic atmospheric response to the rapidly developing Pacific El Niño.

🌧️ Increased chances of above-normal rainfall are forecast across the central and eastern equatorial Pacific east of the Date Line and southern parts of Africa.

☀️ Increased chances of below-normal rainfall are forecast over the tropical Indian Ocean, the equatorial Atlantic Ocean, the Indian subcontinent, the northern Gulf of Guinea, the Greater Horn of Africa, northern South America, northeast (Nordeste), and much of Australia.

Prepare for an El Niño.

WMO’s latest updates confirm that 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. Although some uncertainty remains about El Niño peak strength and timing, most forecast models suggest it will be at least moderate—and possibly strong.

Each El Niño event is unique, but it is typically associated with increased rainfall in parts of southern South America, the southern United States, parts of the Horn of Africa and central Asia, and drier conditions over Central America, northern South America, the Caribbean, Australia, Indonesia, and parts of southern Asia. During the Boreal summer, El Niño’s warm water can fuel hurricanes in the central/eastern Pacific Ocean, while it hinders hurricane formation in the Atlantic Basin.

Its effects vary depending on the intensity, duration, time of year, and how it interacts with other climate variability. Not all regions of the world are affected, and even within a region, impacts can be different.

The WMO community will continue monitoring conditions in the coming months.

Advance seasonal forecasts and are vital to save lives and cushion the impact on our economies and our communities.

Can you spot the areas where land surface temperatures reached records highs for May?

A heatwave is a period where local excess heat accumulates over a sequence of unusually hot days and nights. Intense heatwaves can pose serious health, social, environmental, and economic risks.

Timely heatwave information and help communities prepare, reduce risks, and save lives.

We are likely to experience a new warmest year on record in the next five years.

Annual global mean near-surface temperatures during 2026–2030 are predicted to range between 1.3°C and 1.9°C above the 1850-1900 average, according to a new and report.

The five-year predicted average temperature in the central tropical Pacific indicates a tendency towards El Niño conditions, particularly in 2027 and 2028.
