Set us as preferred As wildfires rage across Canada and the American West, the announcement from federal forecasters that an El Niño warming is forming thousands of miles away in the tropical Pacific Ocean may offer some regions relief — next year, at least.The El Niño climate pattern materializes erratically every two to seven years and can last up to a year.During its tenure, El Niño often brings wetter conditions to the Southern United States.

While extra rain can bring flooding and landslide risks, it can also keep vegetation moist, lowering the potential for wildfires.Forecasters with the National Oceanic and Atmospheric Administration, which announced in June that El Niño had arrived, predict this iteration will be “very strong,” bringing a greater promise of a wet winter.Despite an active El Niño, experts say the Southwestern United States likely won’t feel its damping effect until next year.A recent study from NOAA researchers found that it’s El Niño’s wet fall, winter and spring seasons that often bring a notably milder wildfire season the following summer.Meanwhile, the Western U.S.

is still suffering the consequences of a hot winter and meager snowpack, in part thanks to El Niño’s polar-opposite sister, La Niña, which brought cool ocean water to South America’s Pacific coast and drier conditions to the Southern U.S.through early 2026.“Unfortunately, the ‘helping effect’ of El Niño in much of the United States won’t be felt until sometime next year,” said NOAA Research Meteorologist Andrew Hoell, a study author.

With the most recent La Niña just ending, “we’re still in the crosshairs.”Hoell and his colleagues analyzed nearly four decades of El Niño and La Niña oscillations and wildfire burn areas to understand how often the fire season mirrors the climate cycle.They found...
