Despite the recent warm weather that has hardly felt like fall, Southern Ontario's leaves continue their annual colour transformation. Parks around Lake Huron, Georgian Bay, Lake Simcoe, and extending into the Ottawa Valley now report an approximate 10% change in leaf colours. While no park in Southern Ontario has yet reached 20% colour change, the forthcoming weekend's anticipated colder temperatures are likely to expedite this natural progression as we venture into the coming week.
Please note: This forecast relies on extrapolating data collected from various parks throughout Southern Ontario. Given that some parks do not provide daily updates, we may draw data from adjacent regions to formulate our estimated leaf change predictions. This also means that the data displayed on the map may not exactly match what is being experienced in your backyard.

The peak of fall colours in Southern Ontario typically lasts for about one to two weeks, although the exact duration can vary from year to year depending on weather conditions.
