In early January, extreme high tides (known as King Tides) coincided with a major storm, resulting in many dramatic images submitted by volunteers that reveal the vulnerability of roads, bridges, and other low-lying infrastructure around Humboldt Bay. 

To see some of the best submitted photos from the 2021-22 King Tides, check out our King Tides Photo Album 2021.

If you missed it, there will be another set of King Tides on January 1-3. 
The highest tides of the year (known as King Tides) are coming Saturday & Sunday, December 4 & 5, and all you need to get involved is a smartphone or a camera! 

This year, we are focusing on the old railroad tracks around Humboldt Bay. Built over a century ago when sea level was 18 inches lower than it is today, the railroad hasn't operated in decades. But coal interests are scheming to seize the railroad from the State of California to export coal to Asia via Humboldt Bay. Visit for more info on the growing coalition fighting this terrible proposal.

King Tides are the highest tides of the year which happen during full or new moons around the winster solstice. They provide a glimpse into the future, when higher tides will become more frequent as sea level rises.

On the north end of Eureka, along Eureka Slough just behind Target, there's a pole showing the height of the water level. And there's a sign explaining the relationship between certain water levels and scientific projections of sea level rise.
