El Niño: Meteorologists predict the climate pattern will likely develop by summer

Meteorologists now predict a 92% likelihood of El Niño conditions emerging between June and August 2025, with a probability exceeding 98% by fall. The National Oceanic and Atmospheric Administration (NOAA) confirmed these forecasts, citing weakening Pacific trade winds and warming equatorial waters—hallmarks of the climate pattern. Historically, El Niño reduces hurricane activity in the Northeastern U.S., but global warming has disrupted these patterns, increasing uncertainty. The World Meteorological Organization classified the 2023-2024 El Niño as one of the five strongest on record, contributing to extreme weather like Brazil’s flooding, southern Africa’s droughts, and coral reef die-offs. Jase Bernhardt, a climatologist at Hofstra University, warned that climate change exacerbates these uncertainties, making predictions less reliable. The most recent La Niña phase ended in March 2025, transitioning the planet into a neutral state before El Niño’s expected return. For Long Island, El Niño’s impact is less direct than in other regions, though NOAA meteorologist Nat Johnson noted warmer winters and reduced snowfall in the Northeast during these events. Atlantic hurricane seasons tend to weaken under El Niño, but rising ocean temperatures may offset this trend. The pattern’s global reach includes heightened risks of droughts, floods, and wildfires, as observed in past strong El Niño years. NOAA’s Climate Prediction Center emphasized the high confidence in El Niño’s development, citing data from the past months. The shift from La Niña to El Niño follows natural cycles but aligns with broader climate trends, including record global temperatures. Experts caution that while El Niño’s effects vary by region, its potential for extreme weather demands global preparedness.
