What might change by your visit?

The photographs keep their capture dates when you choose a future visit. A peak date is an estimate for the place named by its source; the trees beside a road or a camera can be on a different schedule.

Wind, rain and frost can change a view between its photograph and your visit. Check the newest pictures and the local weather before leaving.

Two forecasts that agree may simply be reading the same weather, so their agreement is no proof that either is right.

Algonquin sugar-maple record

For Algonquin Highway 60 · Dorset lookout area · Algonquin Provincial Park, Highway 60 · Dorset Scenic Lookout Tower · Algonquin Highlands — Five Viewpoints area.

For the western Highway 60 sugar-maple canopy, the park’s Friends report September 29 as the 2026 peak, September 25 in 2025 and September 27 as the long-term average. This year was two days later than that average. This is one tree, the sugar maple, along one stretch of road; it says nothing about the other trees or about any forecast’s wider window.

Compare the zone and the leaf-drop column, not just the colour label. The archive keeps its north and south divisions, and sometimes records a peak after the weekly reports had stopped. Open each report by its date rather than its heading: when we looked on October 4, the 2026 heading pointed at the 2025 reports.
