About the tides at Arcata Wharf

This is a mixed-tide station. Some days bring a deep low and a shallow low, and a few days have only one of each. The pattern follows the reference station at North Spit, Humboldt Bay. The average range is about 4.7 ft. Spring tides add a little more at both ends. The next spring tides peak on October 28, with a range of 9.5 ft. Neap tides follow today, when the range shrinks to 1.7 ft. In the next 12 months the highest predicted tide here is 8.9 ft on December 24, and the lowest is −2.1 ft on June 6.

Arcata Wharf is a subordinate station. NOAA predicts its tides by adjusting North Spit, Humboldt Bay: highs come about 48 min and lows about 54 min later than there. The nearest other station is Mad River Slough, 2 mi away, where high tide comes about 5 min earlier. For tidal currents, see North Bay Channel at Samoa Channel.

Predictions are based on North Spit, Humboldt Bay.
