High Surf Advisory HIGH SURF ADVISORY  
Mendocino County

  Effective: Fri, 11/6 2:30pm Severity: Minor
  Updated: November 6, 2026 8:45 pm Urgency: Expected
  Expires: Fri, 11/6 10:30pm Certainty: Likely

Areas Affected: Coastal Del Norte - Northern Coastal Humboldt - Southwestern Humboldt - Coastal Mendocino
 
Alert Details:
* WHAT...For the Beach Hazards Statement, increased threat of
sneaker waves expected. For the High Surf Advisory, large
breaking waves 22-24 feet.

* WHERE...Coastal Del Norte, Northern Coastal Humboldt,
Southwestern Humboldt and Coastal Mendocino Counties.

* WHEN...For the Beach Hazards Statement, until midnight PST
tonight. For the High Surf Advisory, from 4 AM to 10 PM PST
Sunday.

* IMPACTS...Dangerous surf conditions and localized beach
erosion. Beachcombing is highly discouraged! Large, unexpected
waves can sweep across the beach without warning, sweeping
people into the sea from rocks, jetties, and beaches. These
sneaker waves can also move large objects such as logs,
crushing anyone caught underneath.

Information:
Don't be fooled by an ocean that looks calm.  There can be
30 minutes of small waves before a sneaker wave strikes.  Avoid
rocks and jetties. Avoid steep beaches.  Stay much farther back
from the water and never turn your back on the ocean.

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.
