Ontario is expected to be affected by an exceptionally strong El Niño, often described as a “super El Niño,” raising questions about whether the province’s peak fall foliage could start later than usual. Multiple outlets report that forecasts point to El Niño conditions that may be among the strongest on record.
Experts cited by the outlets say the main impact is likely related to timing rather than a complete loss of fall colour. They note that foliage development depends on a mix of weather factors—such as temperature and rainfall—rather than El Niño alone. While some conditions associated with El Niño can shift seasonal patterns, sources also emphasize that Ontario’s fall colour season typically continues and can still deliver strong results.
The coverage broadly aligns in framing: all outlets connect the forecasted El Niño to potential changes in the fall outlook, particularly the onset of peak colour. None of the sources suggest guaranteed outcomes, instead describing uncertainty in how regional weather will respond.
