About Sullivan Falls
Sullivan Falls sits on the Sullivan River in Sullivan, Maine, offering a peaceful, picture-postcard cascade that draws locals and day visitors looking for a quiet nature escape. The falls are best appreciated up close, where the rushing water and wooded surroundings create a scenic spot for photography, a short picnic, or a restorative stop during a coastal Maine outing. The tread can be uneven and portions of the route are faint or unmarked, so bring sturdy footwear and basic route-finding sense. There are limited developed facilities at the site; the nearest maintained campground is Schoodic Woods Campground, about 19.6 km away.

How we calculate this
This is a transparent outlook, not a precise forecast. We take the waterfall's current flow strength (how it ranks against its historical normal for today, from the nearest USGS stream gauge), carry that ranking forward along the gauge's seasonal curve, and nudge it for forecast rain. Confidence is highest for the next day or two and falls further out. Always check official conditions and your own judgment before visiting — high flows can be dangerous.

Winter safety. Frozen falls are the one waterfall trip with a documented injury pattern: falling ice, and ice-glazed rock and trail. Wear microspikes, keep well back from the base and from overhangs, and never walk out on ice over moving water.
Estimate from Open-Meteo daily temperatures at the falls, the LiDAR-measured facing direction, and the nearest stream gauge. It is a likelihood, not a report from the trail. See every frozen waterfall in Maine.
