El Niño impact on North American fall foliage
Overview
A strengthening El Niño climate pattern, described by some experts as a ‘Super El Nino’, is expected to influence the timing and quality of fall foliage in parts of North America.
In the Chicago region, scientists at The Morton Arboretum suggest that warmer-than-average temperatures could delay the onset of autumn colors. While higher precipitation has recently offset some drought effects, the color season may become compressed, with leaves changing rapidly once freezing temperatures arrive.
Similarly, in Ontario, experts anticipate that warmer autumn temperatures may delay the appearance of vibrant pigments. However, because trees have not faced the same level of heat and rainfall stress as in previous years, the color progression could potentially be prolonged and more vivid.
