About this data
Predictions for Koyuk, Koyuk Inlet are computed from NOAA CO-OPS harmonic constituents using Ebb's on-device engine (a Schureman/pytides harmonic model). They are astronomical tide predictions and do not account for weather, wind, or barometric pressure, which can shift real water levels. Solunar bite windows are a fishing-planning heuristic, not a guarantee. Ebb is a fishing- and trip-planning tool, not a navigation product — always consult NOAA Tides & Currents and official sources for navigation-critical decisions.
