UN weather agency warns strong El Nino to intensify from August
The United Nations weather agency warned on Friday that a strong El Nino is expected to intensify starting in August, warning that the phenomenon is likely to
increase above-normal temperatures globally and significantly shift rainfall patterns.
El Nino, a period of warming of sea surface temperatures in the central and eastern Pacific Ocean, will continue to steadily intensify into a strong event during August–October 2026.
In addition to a strengthening El Nino, a positive Indian Ocean Dipole (IOD) is forecast. An IOD is a climate pattern in the western Indian Ocean that becomes warmer on average, while the eastern Indian Ocean becomes cooler than average.
Together, these phenomena can amplify regional climate impacts including drought, floods and wildfire risk, particularly around the Indian Ocean basin.
