About Blaine, Semiahmoo Bay tides
Blaine, Semiahmoo Bay is a NOAA harmonic tide station (9449679): its predictions come from the tidal constituents NOAA derived from water levels measured at this spot. Heights are in feet above MLLW (Mean Lower Low Water), the datum of US nautical charts, so they line up with charted depths.
In the next 30 days, Blaine, Semiahmoo Bay has two highs and two lows on 23 days, one high and one low on 3 days and three turns on 4 days, and the daily range runs from 2.5 to 14.2 ft. That is a mixed tide: some days bring two highs and two lows of clearly different heights, others only one of each.
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, air pressure and river flow can push the real water level above or below the prediction. The daily tidal range in the tables shows how much water moves each day: bigger ranges around the new and full moon mean stronger currents.
