Anything we could not observe is labelled predicted. Every Monday’s forecast is frozen, and in November we publish how we did. Under the hood it is a logistic phenology model, fitted per location against ten years of climate normals, then corrected every day by a greenness index and by human reports. The full methodology is here, including what it gets wrong.

Common questions

When is the best time to see fall colour in Ontario?

It moves from north to south. Algonquin and Killarney typically peak in the last days of September and the first week of October, Muskoka and Haliburton through the first two weeks of October, and southern Ontario including Toronto's ravines from mid to late October.

When the leaves change in Ontario, region by region

Where is the best fall colour near Toronto?

The closest colour to the city is along the Niagara Escarpment: Rattlesnake Point in Milton, Forks of the Credit, Mono Cliffs and Hockley Valley, Spencer Gorge and Dundas Peak, and Scenic Caves in the Blue Mountains. They turn later than the north, usually through the middle of October, so they are the right answer once Algonquin is past.

The Rouge and the Don Valley inside Toronto are the last to turn, often into late October.

The full guide to fall colours near Toronto

When does Algonquin Park peak?

The Friends of Algonquin have recorded the sugar maple peak on the Highway 60 corridor every year since 1973. Across those 53 seasons the mean peak is 27 September, and the record runs from 15 September at the earliest to 9 October at the latest.

That is the historical record rather than a forecast for this year. Algonquin is the only location on this site whose baseline rests on a record that long; the rest are estimated as offsets from it, and each page says which it is.

Algonquin fall colours, and this year's forecast

How long does peak colour last?

Roughly 10 to 14 days in one location, though wind and rain can end it early. That is why we check against webcams and reports rather than trusting the calendar.

Is this a fall foliage report?

Yes, under a different name. The Ontario Parks fall colour report is the province's official weekly status, filed by park staff, and it is one of the four sources here. This site is a daily forecast built on top of it: it predicts the week each location will peak rather than only recording where the colour has already reached.

Fall colors and leaf peeping are the American terms for the same thing, and this is that report. Ontario spells it colour, and everything here is Ontario.

Every source, and what the model gets wrong

Where does the data on this site come from?

Four sources, and every reading on the site records which one it came from and when. The Ontario Parks fall colour report, which parks file themselves. Public webcams, read every day for how green the trees still look. Open-Meteo weather, for cold nights, September warmth, drought and frost. And reports sent in by people who went and looked, each one moderated by a person before it appears.

Anything we could not observe is labelled predicted, on every chip, every marker and every week of the season slider.

The full methodology, including what it gets wrong

How far ahead can you actually predict this?

Honestly, not very far. Inside two weeks the forecast is reasonable; beyond that the confidence band widens. After the season we score every prediction against what happened.

That scorecard is here

Can I send in a report from a trip?

Yes, and they carry real weight: a verified report from the ground outranks the model for that location. Say where you were, what the colour was doing and when you saw it, and add a photo if you have one.
