** PENNSYLVANIA 2025 FALL FOLIAGE FORECAST **
With us heading deeper into September, we are closer to the fall foliage season! Fall foliage is a spectacular sight here in Pennsylvania, which helps to bring in millions of tourists into the state to enjoy the spectacular colors of a variety of trees across our forests and state parks. This map was created based on the recent peak fall foliage times over the last few years, elevation data, recent temperature/precipitation trends, and what is expected with our weather conditions in the future.
In general, I expect fall foliage to peak a little earlier this year than in most regular years, due to the recent cool and dry pattern. The developing drought stress from mid-to-late summer is already causing leaves to drop across portions of the state. While a general warming trend is still expected into mid-September, we will still have plenty of cooler nights to satisfy the leaves changing. The best conditions for fall foliage colors are cool, crisp nights followed by seasonable/warm sunny days.
FALL FOLIAGE PA WEATHER PLUS PROJECTED PEAKS:
AREA A - Leaning toward early October. Exact dates may be anywhere between October 6th - October 13th
AREA B - Leaning toward mid-October. Exact dates may be anywhere between October 13th - October 21st
AREA C - Leaning toward mid to late October. Exact dates may be anywhere between October 21st - October 29th
AREA D - Leaning toward late October to perhaps early November. Exact days may be anywhere from October 29th - November 5th
If our pattern turns windier or more filled with precipitation, this may shift the peak forecasted dates. High wind events will increase the leaf drop rates, and precipitation may help dull colors.
