Some of the highest tides of the year are coming on February 8-9. Please join our King Tide Photo Initiative to help document rising sea levels around Humboldt Bay! Baykeeper volunteers have been documenting King Tides since 2011. To get involved, all you need is a camera or a smartphone.

By capturing images of these extreme high tides, scientists and planners hope to gain insight into how rising sea levels will impact coastal areas in the future. The King Tides Photo Initiative is a great opportunity for Citizen Scientists 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.

Be very cautious of rising water, eroding shorelines, and flooded roadways!
The tides vary by location in both height and peak time. At the North Spit, the tides will peak on:

• Saturday, February 8 @ 10:28 a.m.
• Sunday, February 9 @ 11:18 a.m.

Be sure to check NOAA’s tide predictions for various locations around Humboldt Bay.
Recommended locations to observe high tides include:

  • Halvorsen Park & F Street boardwalk in Eureka
  • Fisherman’s Statue on Woodley Island
  • Arcata Marsh & Wildlife Sanctuary
  • HWY 255 Bridge over Mad River Slough, Manila
  • Liscom Slough on Jackson Ranch Road in Arcata
