Predictions come directly from NOAA CO-OPS harmonic predictions for station 9418767 (North Spit, Humboldt Bay) and are the same data used in official tide tables. Actual water levels can vary with storms and barometric pressure, so treat predictions as planning guidance, not navigation data.
Eureka sits on Humboldt Bay, the largest protected water between San Francisco and Coos Bay. The North and South jetties produce rockfish and lingcod in fishable swell, redtail perch stack along the spits in spring, and the bay itself holds leopard sharks and the occasional halibut all summer. When the salmon are in, the entrance can be shoulder to shoulder.
