Fall Colors in Western Washington to Last Longer Than Usual

This fall, foliage in western Washington is expected to be more vibrant and remain on the trees longer. According to AccuWeather meteorologist Chad Merrill, the next week and a half will be the best time for walks and scenic drives: the region is expecting warmer, drier weather without major storms capable of prematurely bringing down the leaves.

The brilliance of fall foliage depends on how much moisture and nutrients trees have accumulated over the year. Drought has been relatively mild in the western part of the state, while Seattle received 2.32 inches of rain this summer — more than last year. As a result, the area can expect rich shades of gold, bronze, red and orange. In eastern Washington, where drought has remained moderate to severe for a fourth consecutive year, leaves may be duller and fall earlier.

Peak fall color in the Cascade Mountains is forecast for around mid-October, while areas along Interstate 5 are expected to peak in late October and early November. The western slopes of the Cascades will be more colorful than the eastern slopes, where wind and wildfires have already left more trees bare. While the weather remains calm, experts recommend visiting the Olympic Mountains, Mount Baker or the eastern slopes of the North Cascades to see golden larches.
