About Johnstone Passage, Yakutat Bay tides
Tide predictions for Johnstone Passage, Yakutat Bay come from NOAA station 9453215 (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.
Johnstone Passage, Yakutat Bay 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.
The current water temperature near Johnstone Passage, Yakutat Bay is about 56°F, from the nearest reporting buoy (Yakutat, Yakutat Bay, AK buoy YATA2, 3 mi away). Water temperature shapes where fish hold and feed, and tells you what to wear in the water — check it alongside the tide before you head out.
Frequently asked
What time is high tide in Johnstone Passage, Yakutat Bay today?+
Today (Friday, September 11), high tide at Johnstone Passage, Yakutat Bay is at 1:34 AM (11.0 ft), 2:05 PM (10.8 ft). Heights are referenced to MLLW (Mean Lower Low Water).
What time is low tide in Johnstone Passage, Yakutat Bay today?+
Today, low tide at Johnstone Passage, Yakutat Bay is at 7:51 AM (-0.6 ft), 8:12 PM (0.2 ft).
What tidal datum do these Johnstone Passage, Yakutat Bay tide heights use?+
All heights are given in feet relative to MLLW (Mean Lower Low Water), the standard NOAA chart datum for US tidal waters. A tide of 0.0 ft equals the chart datum; negative tides fall below it.
How accurate are these tide predictions?+
These are NOAA harmonic predictions — highly accurate for the astronomical tide. Real water levels can still differ with wind, barometric pressure, and storms, so always check current conditions before getting underway.
What is the water temperature at Johnstone Passage, Yakutat Bay?+
The latest sea-surface temperature near Johnstone Passage, Yakutat Bay is about 56°F, from the nearest reporting buoy (Yakutat, Yakutat Bay, AK buoy YATA2, 3 mi away). Water temperature drives fish behavior and tells you what to wear in the water, so it's worth checking alongside the tide.
