About the tides at Greenhead Slough
Tides here are mixed. On average the two daily highs differ by 1.4 ft, so check which low is the lower one before you head out. The range is large, about 8.8 ft on average. Flats and bars appear and vanish quickly, so keep an eye on the time. That is larger than most Washington stations on this site. From the average lower low to the average higher high, the difference is 10.7 ft. The next spring tides peak on October 27, with a range of 13.6 ft. Neap tides follow today, when the range shrinks to 6.2 ft. In the next 12 months the highest predicted tide here is 12.9 ft on December 24, and the lowest is −2.3 ft on July 5.
This is a prediction station. NOAA calculates its tides from past measurements at this spot, but there is no live gauge today. NOAA measured the tide here in 2016 to set up these predictions. The nearest other station is Naselle River, swing bridge, 5 mi away, where high tide comes about 23 min earlier. For tidal currents, see Baker Bay entrance, E of Sand Island Tower.
