El Niño Promises Vibrant Fall Foliage Across U.S.
US · Published Oct 12, 2026
• This year's El Niño weather pattern is expected to bring wetter and warmer conditions, which could result in brighter fall foliage across the United States.
• According to Don Hagan, a forest ecology expert at Clemson University, the absence of extreme drought conditions during the summer has set the stage for vibrant leaf colors.

Impact & Risks

The wetter and warmer conditions associated with El Niño are expected to enhance the vibrancy of fall foliage, benefiting tourism and outdoor activities in regions known for their autumn colors. However, localized impacts from Hurricane Isais may have stripped leaves in certain areas, slightly diminishing the display. Additionally, the timing and quality of foliage depend on upcoming weather patterns, with mild cold fronts and sunny days being crucial for optimal color development.
