Waterfall Season by State
Peak waterfall season changes from snow-charged Rockies to rain-fed Appalachia. Use this calendar to time your trips.
Pacific Northwest
- November–May delivers constant rain recharge for Oregon and Washington gorge waterfalls.
- Summer sunlight lasts late, but expect lower flow by August unless snowpack was deep.
Sierra Nevada & Southwest
- Sierra waterfalls run wild from April through June as high-country snow melts.
- Desert oases like Havasu Falls keep flow year-round thanks to spring-fed creeks.
Appalachian Highlands
- Late winter rain plus early spring snowmelt light up Georgia, Carolina, and Virginia waterfalls.
- October brings a second surge when tropical systems brush the Blue Ridge.
Great Lakes
- April–May has the highest volumes, but fall color and early winter ice add texture.
- Plan for frozen boardwalks from November through March.
