Leaf-peepers planning Northern Michigan drives this fall may need to wait longer for the region’s most vivid colors. A warmer-than-normal start to the season could slow the breakdown of green chlorophyll in hardwood leaves, delaying the yellows, oranges and reds that draw visitors north.
The early signs are already visible around Alpena. A maple along the drive at Holy Cross Cemetery showed the first hints of red among still-green leaves on Tuesday afternoon, while overnight lows remained milder than usual.
National Weather Service meteorologist Sean Christensen said the Climate Prediction Center’s latest trends point to a warmer start to September than normal. That pattern can slow the seasonal fade of green chlorophyll, which currently masks some of the colors developing inside the leaves.
Day length continues to establish the season’s calendar, but weather determines how bright the final display becomes. The strongest combination is a run of sunny, warm autumn days paired with cool overnight temperatures above freezing.
Why overnight temperatures matter
During sunny days, sugars left in the leaves become more concentrated. Cool nights help hold those sugars in place as green chlorophyll breaks down, allowing red anthocyanin pigments to become more visible.
A hard freeze can interrupt that process by damaging leaf cells and sending foliage to the ground before it reaches its full color. Extended cloudy, wet weather can also make the display look less vivid.
For people watching the forecast, Christensen recommends paying close attention to overnight lows rather than relying only on the seven-day outlook. Warm afternoons can support the transition, but nights in the 30s and 40s that remain above a hard freeze are especially important.
Where Northern Michigan color may be strongest
Dense stands of evergreen trees are less likely to provide a broad fall-color display. Areas dominated by hardwoods—especially maple and oak—offer better chances for vivid scenery.
Among the destinations highlighted in the report is SkyBridge Michigan at Boyne Mountain Resort in Boyne Falls. The 1,200-foot suspension bridge rises about 118 feet above the Boyne Valley. Visitors take a chairlift to the summit before crossing the swaying bridge, which includes a glass-floor section over the hardwood canopy. Seasonal hours typically continue into late October.
Other hardwood-viewing options include the Tunnel of Trees along M-119 between Harbor Springs and Cross Village; Deadman’s Hill Overlook west of U.S. 131 near the Jordan River Valley; Avalanche Preserve in Boyne City; Pigeon River Country State Forest north of Gaylord; and Hartwick Pines State Park near Grayling.
The inland locations can offer especially strong views, although areas with a mix of hardwoods and remaining pine may show more patchy color. Great Lakes shorelines often change several days later than inland forests because lake air remains milder.
When peak color may arrive
Foliage maps and tourism forecasts for 2026 generally place peak color in the northern Lower Peninsula during the second and third weeks of October. That timing is only an estimate. A warm spell, drought stress or an early freeze could move the peak by about a week in either direction.
For Alpena residents and visitors, the practical takeaway is to monitor overnight temperatures as autumn approaches. A stretch of warm, sunny days followed by cool nights may produce the brightest hillsides, while continued warmth or an early freeze could change the timing of the region’s fall-color show.
