At the North Spit, the tides will peak at the following times:
  • Saturday, Jan. 1 at 9:39 am 
  • Sunday, Jan. 2 at  10:30 am
  • Monday, Jan. 3 at 11:21 am

These King Tides are predicted to reach from 8.38-8.47’ but could be higher depending on rainfall, atmospheric pressure, and wind. 

Please be very cautious of rising water, eroding shorelines, flooded roadways, and moving vehicles. 

Tides vary by location in both height and peak time. Check NOAA’s tide predictions for various locations around Humboldt Bay. The best photos show the water level next to familiar landmarks such as roads, bridge supports, piers, etc. 

By capturing images of these extreme high tides, we gain insights into how rising sea levels will impact coastal areas in the not-so-distant future. The King Tides Photo Initiative is a great opportunity for volunteers to contribute to a long-term dataset, while helping inform scientists, residents, and planners about the need to plan for the coming changes to our natural and built environments.

Some great spots to observe King Tides include: 

  • Halvorsen Park in Eureka 
  • Fisherman’s Statue on Woodley Island
  • Arcata Marsh & Wildlife Sanctuary
  • Mad River Slough Bridge on Highway 255 in Manila
  • Liscom Slough on Jackson Ranch Road in Arcata
  • King Salmon
Baykeeper volunteers have been documenting King Tides since 2011, collecting over 1,000 images. Check out some of the past photos on our Humboldt Bay King Tides Photo album.
