Coastal Flood Advisory
Coastal Flood Advisory issued November 12 at 3:28PM PST until November 13 at 3:00PM PST by NWS Eureka CA (Expires: November 13, 2026 5:00 pm)
Show Alert Details & Instructions
Description:
* WHAT...For the High Surf Warning, Dangerously large breaking
waves 30 to 35 feet. For the Coastal Flood Advisory, High
astronomical tides will cause minor flooding in low lying areas
around Humboldt Bay. 1.5 to 2.2 feet of saltwater inundation
above ground level is possible near shorelines and tidal
waterways. Between 8.7 and 8.9 feet MLLW at the North Spit tide
gauge is predicted.
* WHERE...Northern Coastal Humboldt County.
* WHEN...For the High Surf Warning, from 1 PM Friday to 4 AM PST
Sunday. For the Coastal Flood Advisory, from 11 AM to 3 PM PST
Friday. High tide is at 1:04pm at the Humboldt Bay North Spit
tide gauge. Saltwater inundation will be possible 1 to 2 hours
before and after high tide.
* IMPACTS...Flooding of low lying areas around Humboldt Bay
including parks and roads with only isolated closures
expected. Flooding will likely impact Jackson Ranch Road in
the Arcata Bottoms and several roads in King Salmon. Breaking
waves can sweep people off jetties and docks, and into
dangerous seas. Life- threatening surf conditions and
significant beach erosion can be expected.
* ADDITIONAL DETAILS...While astronomical tides are decreasing
each day, persistent southerly winds are aiding in raising water
levels for Humboldt Bay. The beginning of a very large incoming
swell could enhance coastal flooding if they overlap, but they
aren't anticipated to do so or will not overlap for long. After
only brief improvement in high swell late Saturday through
Sunday, a second large swell is forecast late Sunday through
Monday.
Instructions:
A Coastal Flood Advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.
Feet Above Ground is locally defined as feet above the Highest
Astronomical Tide or HAT.
Large breaking waves along the coast will lead to increased wave
run-up on beaches with waves topping and washing over large rocks
and jetties. These large waves can be erratic and unpredictable.
Use extra caution near the surf zone as these large waves will be
capable of sweeping people into the frigid and turbulent ocean
water. Mariners traversing the bar are urged to exercise extreme
caution or stay in port until the threat subsides. Please contact
the U.S. Coast Guard for information regarding harbor and bar
closures.

About Trinidad & Humboldt Lagoons
Trinidad & Humboldt Lagoons is an outdoor-planning page for Trinidad coast through the lagoon state parks. It has a distinct purpose centered on lagoon paddling, exposed beaches, coastal fog, and wind, with the forecast used to choose the safest and most comfortable version of the day.
Make the Most of a Trinidad & Humboldt Lagoons Day
Start by comparing conditions across Trinidad, Trinidad Head, and the rest of the coverage area. Choose among hiking, paddling, camping based on wind, precipitation, temperature, visibility, water or trail conditions, road access, smoke, and available daylight.
Weather Tips for Trinidad & Humboldt Lagoons
- Conditions around Trinidad coast through the lagoon state parks can differ sharply from nearby towns; lagoon paddling, exposed beaches, coastal fog, and wind are the main planning variables.
- Check wind, waves, current, tides where relevant, water temperature, and lightning before launching; keep a land-based alternative ready.
- Cold ocean water, marine fog, swell, beach wind, and winter storms can matter even when the inland forecast looks mild.
- Crowds and parking can narrow the useful weather window, so arrive early and keep a lower-commitment nearby option.

7-Day Forecast for Trinidad & Humboldt Lagoons
Trinidad & Humboldt Lagoons Weather by Season
Winter
At Trinidad & Humboldt Lagoons, pacific storms bring the wettest, windiest conditions, with slick bluff trails, high surf, and occasional coastal-road trouble. Breaks between systems can still support short hikes, but cold ocean water and fast-changing marine weather favor conservative shoreline and paddling plans.
Spring
Around Trinidad coast through the lagoon state parks, rain becomes less persistent, yet muddy trails, cool water, fog, and breezy headlands remain common planning factors. Longer daylight creates good hiking and camping windows when roads and trail surfaces have had time to drain.
Summer
For lagoon paddling, exposed beaches, coastal fog, and wind, marine layer and fog often keep mornings cool while inland pockets can be much warmer. Afternoon beach wind, cold water, limited visibility, and crowded parking can matter more than the forecast temperature.
Fall
Near Trinidad and the surrounding area, early fall can offer clearer, calmer outdoor windows before the main rainy season returns. Later fall brings shorter days, stronger systems, wetter trails, and a greater need to check coastal roads and campground conditions.
Key Climate Data Points
- Warmest months: Late summer into early fall, especially away from persistent fog.
- Coolest months: Winter mornings and foggy summer days.
- Wettest season: Late fall through winter.
- Driest season: Mid-to-late summer.
- Best outdoor window: Late summer and early fall for hiking, paddling, and camping when wind and fog cooperate.
