Great white sharks breaching off California beaches can be thrilling and concerning moments for beachgoers. These rare events, like a recent breach at Marina State Beach, reveal a natural seasonal pattern that occurs each fall. This explainer breaks down why these sharks appear nearshore in autumn, what ‘Sharktober’ means, and practical safety guidance for people enjoying the California coast.
What Was the Recent Shark Breach in Marina, California?
On October 17, 2026, a great white shark was recorded breaching just off the shore at Marina State Beach in Monterey County, California. The sighting was captured on video by local resident Erin King and independently confirmed by California State Parks with matching footage from a Surfline camera at The Sanctuary Beach Resort.[1][2]
The rare moment prompted a shark advisory for Marina State Beach, reminding the public that this behavior is typical for fall months along the Central Coast.
Why do Great White Sharks Breach California Beaches in Fall?
This seasonal pattern is no coincidence. Autumn, particularly from September through November, is when mature great white sharks migrate from offshore areas back toward California’s coast.[3]
Migration and Feeding Behavior
- Sharks spend many months offshore near an area called the “White Shark Cafe,” a remote spot in the Pacific where they gather in spring and summer.
- In the fall, they undertake long-distance migrations back toward the California coastline, including areas like Monterey Bay, Point Reyes, and the Farallon Islands.[3]
- This migration is motivated primarily by feeding opportunities. These locations are rich with key prey such as seals and sea lions, which haul out on rocky headlands and beaches in cooler months.
- The sharks’ hunting behaviors include breaching—the act of leaping out of the water to capture prey like seals—resulting in dramatic sightings close to shore.[1][3]
What is ‘Sharktober’?
“Sharktober” is a colloquial term used by scientists and ocean advocacy groups to describe the peak season of great white shark activity along California’s coast during fall.[3]
While the term can evoke fear, conservation organizations like Shark Stewards encourage people to see it as a celebration of the sharks’ important ecological role, not a threat. Great whites help maintain healthy, balanced marine ecosystems by preying on seals and other species.[3]
How Common Are Shark Interactions with People During This Time?
Despite increased sightings and occasional beach advisories, shark attacks remain extremely rare. As shark expert Chris Lowe from Cal State Long Beach noted, “sharks are around people all the time.” The recent Marina breach was an unusual but brief event, and no attacks were reported.[3]
What Safety Measures Should Beachgoers Take?
- Check for Shark Advisories: Always look for and heed official beach advisories or warning signs, especially during Sharktober months.[1][2]
- Avoid Swimming During Dusk and Dawn: Shark activity tends to be higher around these times.
- Stay in Groups: Sharks are more likely to approach isolated individuals.
- Avoid Areas With Seals or Sea Lions: Sharks follow their prey, so steer clear of rocky outcroppings or haul-out spots.
- Refrain From Wearing Shiny Jewelry or Bright Clothing: Avoid attracting sharks by mimicking fish scales or contrasting colors.
- Report Sightings: If you see unusual shark activity, notify lifeguards or local authorities promptly.[2]
Why This Matters
Understanding the seasonal patterns of great white sharks can help the public appreciate these predators and coexist safely. Shark breaches, while dramatic, are natural behaviors connected to the local marine ecosystem’s rhythm. They highlight the thriving marine life along California’s coast but also call for respectful caution.
Summary
- Great white sharks breach near California beaches mainly during fall months as part of feeding and migration behaviors.
- “Sharktober” marks the seasonal period of heightened shark activity coinciding with their return to coastal waters.
- The recent breach at Marina State Beach was verified by multiple independent sources and prompted a shark advisory.
- While sightings can be startling, shark attacks are rare, and simple safety measures help reduce risk.
- Appreciating these events supports marine conservation and awareness of the sharks’ role in ocean health.

- Chris Cerney on Instagram: "SHARK VIDEO IS REAL: HERE’S WHY
Many people called this Marina State Beach shark video fake. But a second camera, the Surfline camera at The Sanctuary Beach Resort, captured a breach in the same area at the same time, and California State Parks confirmed a shark breached there.
The video reached me first, before anyone checked a surf camera. For it to be fake, it would have to match a real breach in the same area, in the same minute.
State Parks confirmed the breach, not the phone video’s authenticity. Species is not known, but they say it appears to match great white behavior in Monterey Bay in the fall and winter. Shark advisory signs will be posted.
My two reports on this have now been viewed nearly 4 million times across Facebook, Instagram and TikTok.
Check the advisory signs before entering the water. If you recorded anything Saturday, send it to my tipline: chriscerney.org/upload
