The third wave of this winter's King Tides are coming on January 11-12, 2021. Please join our King Tide Photo Initiative to help document rising sea levels around Humboldt Bay! Photo:Expanding erosion under the railroad dike next to Highway 101 at Bracut, Jan. 11, 2020.These tides will peak at 9:30 a.m. on Jan. 11 and 10:20 a.m. on Jan. 12 at the North Spit tide gage (check your favorite tide tables or NOAA’s tide predictions for various locations). These high tides are predicted to reach 8.4’ but could be higher depending on rainfall, atmospheric pressure, and wind. Corresponding very low tides ("minus tides") mean excellent mid-day tidepooling!Baykeeper volunteers have been documenting King Tides since 2011. To get involved, all you need is a camera or a smartphone and submit your photos to This email address is being protected from spambots.

The King Tides Photo Initiative is a great opportunity to contribute to a long-term dataset, while helping inform residents and decisionmakers about the need to plan for the coming changes to our natural and built environments.Recommended locations to observe high tides include:
Halvorsen Park and the F Street boardwalk in Eureka
Eureka Slough behind Target: This site has a pole with water level measurements, and a sign showing current projections of sea level rise.
