80% chance of 'El Nino' developing by Jul. 2026, 33% chance it could rise to 'super El Nino': US forecasters

There is supposedly an 80 per cent chance of "El Nino" developing by July 2026, according to forecasters at the U.S. National Oceanic and Atmospheric Administration (NOAA).

El Nino is a natural climate pattern that can disrupt weather worldwide, the Radio France Internationale (RFI) reported.

RFI added that it develops in the Pacific every two to seven years and brings drought to some regions and heavy rain to others.

Effects

El Nino would also strongly impact marine life off the Pacific Coast, NOAA's website stated, adding that warmer waters could also bring tropical species into areas that are too cold.

According to the RFI, this reportedly saw sea temperatures in key parts of the equatorial Pacific climbing quickly, with a large pool of unusually warm water building beneath the surface.

In addition, Pacific temperatures could apparently rise by 2.5°C or more above average later in 2026, based on predictions by several weather services, RFI reported.

It added that there had only been three El Ninos that have crossed the 2°C mark. These happened in 1982, 1997, and 2015.

Episodes

According to NOAA, there is a one in three chance of this episode reaching 2°C or above.

That would put it in the "super El Nino" territory, RFI reported the administration as saying.

However, RFI noted that according to scientists, its final strength would depend on winds that would still be difficult to predict.

RFI reported that the strongest El Ninos usually form when trade winds weaken across the Pacific.

This would allow more warm water to spread across the ocean surface, it stated, adding that those winds could also strengthen unexpectedly.

The NOAA noted that while episodes typically last nine to 12 months, they may last for years at times, and do not occur on a regular schedule.
