A worrying change is currently being seen in the world’s climate system. The natural process of increasing temperatures in the Pacific Ocean, El Niño ‘, has become very strong in mid-2026.
The latest Global Climate Report from July 2026 says that the Pacific Ocean’s temperature has risen by about 1.7° to 2° Celsius above normal. This rise has raised the risk of extreme weather around the world many times. This ‘Super El Niño’ has raised the global average temperature. It is also a big problem for food security and the environment.
Scientific background of El Niño & La Niña (El Niño-Southern Oscillation): When the sea surface temperature in the Pacific Ocean becomes unusually warm than normal, it is called El Niño. And the opposite situation, when the sea water is cold, is called La Niña. Science
Currently, in 2026, we are going through a strong El Niño phase. Meteorologists call it an “evolutionary crisis” because it has sped up the way the ocean and atmosphere interact like never before.
Global situation in July 2026: The World Meteorological Organization (WMO) and climate research groups worldwide have confirmed their new report that El Niño will get much stronger quickly from July to September.
There is a chance that the rise in sea temperatures in the central Pacific Ocean will cause more extreme heat (heatwaves), unusual rainfall, and more storms (hurricanes and typhoons) around the world. Its effects have already begun to be visible in almost all countries in the equatorial region.
The effect of El Niño in Bangladesh is not always clear and straightforward. According to historical data, rainfall variations are seen in Bangladesh during El Niño years. However, some specific risks are being observed in the case of this strong El Niño in 2026:
Impact on monsoon winds: The effect of El Niño changes the tendency of cloud formation in the Pacific Ocean, which can weaken the South Asian monsoon. As a result, there is a risk of reduced rainfall during the rainy season or prolonged drought.
Heat waves: El Niño has been showing a tendency to increase the average temperature of the land of Bangladesh, which has been proven by the intense heat waves in the last few months.
Heterogeneous effects: Research has shown that not all El Niño years cause drought in Bangladesh; rather, during the strong El Niño of 2015-16, Bangladesh also received significant rainfall. This is due to the temperature of the Bay of Bengal, the Indian Ocean Dipole (IOD), and local low pressure, which often lessen or change the impact of El Niño.
Why is it difficult to judge the weather of Bangladesh based on El Niño alone? Although El Niño is an important influencer in determining the weather patterns in Bangladesh, it is not the only regulator. Our location affects the Madden–Julian oscillation (MJO), the rough weather in the Bay of Bengal, and the power of local winds. These factors are very important here.
Therefore, the idea that there will be severe drought in Bangladesh when El Niño starts is not entirely correct. Rather, it combines with regional climate factors to create a complex weather pattern.
This strong El Niño in 2026 reminds us that climate change is no longer a future event, but a reality of the present. The strong weather cycle is putting not just Bangladesh’s weather, but also the whole farming system and water management in South Asia at risk. ClimateChange & Global Warming
We need to regularly check information about El Niño. We should also focus on creating agriculture and infrastructure that can withstand climate change. Greenpage will always present you with objective and scientific information on this complex environmental change.
