Models indicate a 69% chance of a record-strength El Niño by year-end
Forecasts give a 69% probability that the current El Niño will become the strongest event on record since 1950, with potential global weather impacts extending into 2027.
Forecast models give El Niño a 69% chance of becoming the strongest event on record since systematic observations began in 1950, raising the possibility of a so-called “Super El Niño.” Sea-surface temperatures in the equatorial Pacific are currently about 1.4 °C above average, close to the 2 °C threshold required for a three-month Super El Niño classification. Meteorologists expect average ocean temperatures to rise to between 3.0 °C and 3.4 °C by November-December, with some models projecting up to 4 °C.
"If these averages hold, this system will blow every historical event out of the water," said Noah Bergren, a meteorologist at FOX 35 Orlando.
El Niño typically reduces tropical cyclone activity in the Atlantic while increasing storm activity in the eastern and central Pacific. The phenomenon can also affect weather patterns far beyond the Pacific basin, potentially bringing wetter winters to the southern United States and Florida, and influencing precipitation in Europe. Analysts note that past strong El Niño events, such as those in 2015-2016 and 1997-1998, were associated with higher temperatures globally and, in some cases, severe weather outbreaks.
Bergren added that the extended warmth could push global temperatures well above average in 2027, underscoring the broader climate implications of a prolonged, high-intensity El Niño event.
