Lost Coast Trail

The Beach Hazards Statement from NWS Eureka is active until 10 PM tonight — this typically means elevated surf and sneaker wave risk on the exposed beach sections, which is a lot of the Lost Coast Trail. If you're hitting the trailhead this afternoon, time your beach travel after the statement expires or stay high on the inland bypass sections until then. By tomorrow morning you're clear of the advisory and Monday looks fine — mostly cloudy, 54°F, light SE winds, essentially dry.

Monday night is where the trip changes. 80% precip chance with light rain, and that carries straight through Tuesday at the same probability. Temps stay above freezing (43–49°F) so this is all rain at trail elevation, no snowmelt factor. The concern is the coastal stream crossings — Gitchell Creek, Whale Gulch, and the Miller Flat drainages — which can spike fast after rain on this steep, short-drainage coastline. You won't get much warning from rising water before it becomes a problem. The USGS gauges available for this briefing are all inland Central Coast stations and don't reflect Lost Coast hydrology, so treat crossing conditions after Tuesday's rain as unknown. If you hit a crossing that's thigh-deep and moving fast on Tuesday afternoon, wait it out — these drainages drain quickly once rain stops.

Tuesday night clears to partly cloudy with precip dropping to 20%, and Wednesday is the gem of the trip: mostly sunny, nearly calm winds out of NNE, 52°F. That's a great day for the beach miles and the King Range views. Plan your itinerary to put your biggest mileage days on Monday and Wednesday, and keep Tuesday as a lighter day with flexibility to pause at crossings if needed.

Daylight is your other real constraint. Sunset at 5:13 PM gives you about 10.5 hours of usable light. On the southern sections, the beach is your trail — navigation is easy but hiking dark on wet cobble near active surf is not. Build your camp-by times around 4:30 PM to give yourself a buffer before golden hour bleeds into dark. Headlamps are obviously standard kit, but the point is to not be mid-crossing or mid-beach-section when light goes.
