Fall foliage in Rhode Island

Rhode Island moves from the western woods to the bay over about two weeks. Arcadia and the South County forests turn in the third week of October; the Scituate Reservoir and the Blackstone Valley follow toward the end of the month; the bay shore at Colt State Park, Beavertail and Newport finishes in the last days of October. Red maple and oak dominate, with hickory and birch for gold. The water keeps the coast a few days behind the interior.

Those are the months when color is present somewhere in Rhode Island, from its highest ground to its lowest. Any one location changes over a much shorter period than that.

Why the timing shifts from year to year

Shortening days start the process, so most places in Rhode Island change at close to their usual time each year. Within the state, elevation and latitude account for most of the difference: higher and more northern ground generally changes first, and lower, sheltered ground last. Weather has more effect on how strong the color is than on when it appears. Cool nights and sunny days favor the reds, a dry summer mutes them, and a hard freeze or a windstorm can strip a slope in a day. What determines the timing goes through this in detail.

Timing for a specific place

This page describes a whole state, which is about as precise as a season can be described in words. Conditions at one overlook on one weekend are a narrower question, and that is the one Fallcast answers: an expected period of color for a specific location, with a confidence attached, updated through the season as the trees change. It is coming to iPhone this fall.
