The National Oceanic and Atmospheric Administration in the United States confirmed Equitorial sea surface temperatures (SSTs) are near to above average, across the central and eastern Pacific Ocean.
This means there is now an 82% chance that an El Nino could emerge between May and July this year.
The El Nino could also continue through the Northern Hemisphere from December into February 2027.
It is warmer than average sea surface temperatures in the central and eastern tropical Pacific Ocean.
Above average temperatures were also confirmed in global oceans, in the last four weeks.
Scientists at the Climate prediction centre are also concerned about wind and pressure, related to the Madden Julian Oscillation (MJO), which could negatively affect conditions on the surface.
They are tracking a massive wave of warm water crossing the Pacific.
