Tideline is a beach-discovery and water-safety app for Washington's shoreline — built by Windward Holdings LLC, now piloting on California's Central Coast. Tide-aware conditions, legal access, surf spots, and reports from people who were just there.
Filter by activity, surf conditions, and how far you're willing to walk in.
Tide-aware timing and legal access badges, so you're not guessing at the trailhead.
Community field reports, location-verified, keep conditions current between visits.
Every access point in Tideline is checked against NOAA tide stations and verified in the field — starting with Puget Sound, expanding across the state, and now piloting a first region outside Washington on California's Central Coast.
