About Koyuk, Koyuk Inlet tides
Tide predictions for Koyuk, Koyuk Inlet come from NOAA station 9469031 (Alaska), computed from long-term harmonic analysis of observed water levels. Heights are shown in feet relative to MLLW (Mean Lower Low Water) — the same datum used on US nautical charts — so they line up directly with charted depths.
Koyuk, Koyuk Inlet typically sees a mixed semidiurnal tide, with two highs and two lows of differing heights each day. Use the curve above to time a harbor entrance, a beach walk, fishing a moving tide, or clearing a shallow bar — and remember that wind and pressure can push the real water level above or below prediction. The daily tidal range in the 30-day table shows how much water moves each day: bigger ranges around the new and full moon mean stronger currents.
Frequently asked
What time is high tide in Koyuk, Koyuk Inlet today?+
Today (Tuesday, July 21), high tide at Koyuk, Koyuk Inlet is at 9:51 AM (3.0 ft), 7:59 PM (2.1 ft). Heights are referenced to MLLW (Mean Lower Low Water).
