The global climate system is currently showing signs of developing **El Niño conditions**,
a major climate phenomenon that can significantly influence temperature, rainfall
patterns, and extreme weather events worldwide. According to recent global assessments
and research by meteorological experts, the 2026 El Niño event is expected to strengthen
in the coming months and may have important impacts on Sri Lanka’s weather conditions.

## **What is El Niño?**

El Niño is one phase of the large-scale atmospheric and oceanic phenomenon known
as the **El Niño–Southern Oscillation (ENSO)**, which develops over the Pacific 
Ocean region. This condition occurs when sea surface temperatures in the tropical
Pacific Ocean become warmer than normal, disrupting regular atmospheric circulation
and altering global wind patterns. Typically, El Niño events occur every **2 to 
7 years**, and their strength can vary from weak to strong, influencing weather 
systems across many parts of the world.

## **How El Niño Affects Weather Patterns**

According to research conducted by the **Department of Meteorology**, the weather
impacts associated with ENSO depend on when the event begins and how intense it 
becomes. Climate experts categorize these events as weak, moderate, or strong, and
each level can produce different effects on rainfall and temperature distribution.

Scientists also note that another climate factor known as the **Indian Ocean Dipole(
IOD)** can develop at the same time as El Niño. The IOD refers to changes in sea
surface temperatures in the Indian Ocean, which may further influence weather patterns
in South Asia, including Sri Lanka.

The Department of Meteorology continuously monitors these climate developments and
includes updated information in its monthly seasonal weather forecasts.

## **Current Global Situation**

According to the **World Meteorological Organization (WMO)** based in Geneva, Switzerland,
warmer-than-average sea surface temperatures in the tropical Pacific Ocean are currently
contributing to the development of El Niño conditions.

Meteorologists report that El Niño is strengthening and is expected to affect global
temperature and rainfall patterns throughout the coming months. The WMO has also
warned that the risk of **extreme weather events** may increase worldwide as the
phenomenon develops further.

## **Climate Messages for 2026**

Several important climate trends have been identified as El Niño conditions continue
to develop:

 * Warmer ocean waters are driving the development of El Niño conditions.
 * El Niño generally increases global temperatures and contributes to more extreme
   weather patterns. Above-normal temperatures are expected in many regions during
   the **June to August 2026 period**. Improved weather forecasting systems are 
   helping communities prepare for climate-related risks. Public awareness and preparedness
   remain essential for effective planning and disaster risk management.

## **Probability of El Niño in 2026**

According to the latest **WMO ENSO Outlook**, there is currently an **80% probability**
that El Niño conditions will occur during the **June to August 2026 period**.

Climate models indicate that these conditions are likely to continue until at least**
November 2026**, with forecasts showing a **90% or greater probability** that El
Niño conditions will persist beyond that period.

Although some uncertainty remains regarding the exact strength and peak timing of
the event, most global climate models suggest that El Niño will likely reach **moderate
intensity**, with the possibility of becoming a **strong event** later in the year.

## **Possible Impact on Sri Lanka Rainfall Patterns**

Research conducted by Sri Lanka’s **Department of Meteorology**, using nearly **
75 years of historical weather data**, shows that El Niño conditions can significantly
alter the country’s normal monthly rainfall patterns.

During El Niño years, rainfall levels in Sri Lanka may either increase or decrease
compared to long-term monthly averages depending on the season and regional climate
conditions.

These rainfall variations can affect agriculture, water resources, hydropower generation,
and disaster management planning. Weather experts emphasize that close monitoring
and early preparation are essential as climate conditions continue to evolve.

## **Need for Preparedness**

As El Niño develops further in 2026, governments, businesses, farmers, and the general
public are encouraged to stay informed through official weather updates and seasonal
climate forecasts.

Understanding these climate patterns helps communities make informed decisions, 
reduce risks, and better prepare for possible extreme weather conditions in the 
months ahead.

The Department of Meteorology will continue monitoring global climate developments
and provide updated forecasts regularly to support national preparedness efforts.
