About Coos Bay tides
Tide predictions for Coos Bay come from NOAA station 9432845 (Oregon), 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.
Coos 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.
Frequently asked
What time is high tide in Coos Bay today?+
Today (Tuesday, July 21), high tide at Coos Bay is at 7:47 AM (4.7 ft), 7:55 PM (6.7 ft). Heights are referenced to MLLW (Mean Lower Low Water).
What time is low tide in Coos Bay today?+
Today, low tide at Coos Bay is at 1:53 AM (1.0 ft), 1:19 PM (1.8 ft).
What tidal datum do these Coos 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.
