Overview
- Northern New England is forecast to rebound this autumn, with experts saying peak color should arrive in late September into early October because recent heavy snow and spring rains improved soil moisture.
- Explore Fall is rolling out an app this season that the site's founder says will collect live, crowdsourced foliage reports to refine its interactive map, which the service reports averages about plus or minus three days of accuracy.
- Forecasters warn that a developing Super El Niño and September–October weather remain the main wildcards that could either extend and deepen colors with cool nights and light rain or shorten and delay displays with warm, dry, or stormy conditions.
- Popular destinations will see uneven results: Great Smoky Mountains is expected to peak around mid‑October and face heavy visitor congestion that the National Park Service says can be eased with shuttle use, while Colorado aspens may be muted because of low winter snowpack.
- Snowmelt and spring moisture matter because they refill soil water that trees use to sustain leaf pigments; without that moisture, stressed trees can show a short, early 'false fall' of muted color and premature leaf drop.
