Overview

• Ontario experienced higher than normal temperatures in September, particularly impacting the Greater Toronto Area.
• Experts indicate that optimal fall colors require a combination of sunny and cold weather, which was lacking this year.
• Vibrant foliage typically results from a mix of chlorophyll, carotenoids, and anthocyanins in leaves, influenced by weather conditions.
• Climate change is contributing to a trend of warmer falls, potentially leading to less colorful foliage in the future.
• Recent cold snaps could still enhance colors in some areas, though the display is expected to be shorter than in previous years.
