The Southern United States may benefit from increased rainfall during El Niño, which could reduce wildfire risks by keeping vegetation moist. However, this wetter weather also raises the potential for flooding and landslides. Northern regions, including parts of Canada and the northern U.S., may experience drier and warmer conditions, which could exacerbate wildfire risks. The effects of El Niño are not guaranteed, as other ecological and weather factors can influence outcomes. For example, Arizona and New Mexico often see reduced wildfire activity due to unique summer monsoon rains.
