Plan a fall trip without pretending “peak color” is one exact number
Use historical foliage timing to choose the broad window, current ground observations to add context, and first-freeze information as a separate seasonal signal.
Optional device location is rounded before lookup and is not sent to analytics.
Check the season from two angles
Fall Color Timing
Historical USA-NPN satellite timing plus separate recent Nature’s Notebook colored-leaf observations and current weather context.
First Freeze Context
See historical fall freeze probabilities and the current NWS cold forecast without using either one as a foliage percentage.
Historical timing is a window
Satellite greendown history can show when autumn transition usually occurs and how variable that timing has been. That is more defensible than presenting an unsupported nationwide “82% peak” value.
Ground observations are evidence, not a statewide score
Recent USA-NPN Colored leaves records describe individual monitored plants. They can reflect normal autumn change or stress color, so they remain a separate evidence layer rather than moving the historical timing model.
Cold weather is context, not a color meter
Freeze climatology and the current forecast can matter for a trip, but neither directly measures the surrounding landscape’s color. The tools keep those claims separate.
Michigan remains its own deeper destination
Michigan fall intent should continue to use the established Michigan Fall Color Map, which has deeper state-specific reporting.
