A decaying whale carcass off the coast of Martin’s Beach, south of Half Moon Bay, has drawn a gathering of juvenile and adult great white sharks, serving as a visual indicator of shifting marine behavior along the California coastline. Drone operator Sammy Rigling documented between six and eight sharks feeding on the remains, with some predators estimated to reach 15 feet in length. This event follows a series of recent shark sightings near Santa Barbara and Aptos, as ocean temperatures and El Niño climate patterns influence predator migration.
Why Are More Sharks Appearing Near California Beaches?
Marine experts attribute the surge in shark sightings to a combination of abnormally warm ocean temperatures and the onset of an El Niño cycle. According to reports from regional observers, these environmental shifts are pushing juvenile white sharks northward from their typical habitats in Mexico into waters stretching from Southern California to Monterey. This seasonal movement, often described by observers as a “sharky summer,” creates higher probabilities for encounters between humans and predators in areas traditionally known as natural habitats for the species.
How Do Recent Sightings Compare to Past Encounters?
The recent feeding frenzy at Martin’s Beach mirrors a pattern of increased proximity between sharks and coastal recreation. Earlier in June, a large shark was observed swimming near a surfer off the coast of Aptos, near Santa Cruz. This follows a high-profile incident where two paddle boarders were tracked by a great white shark off the coast of Santa Barbara. Robert Kagan, one of the paddle boarders, told ABC that the encounter shifted from an adrenaline-filled search to a “terrified” retreat to shore once the predator was sighted.

Comparison of Recent Shark Activity
| Location | Type of Activity | Reported Source |
|---|---|---|
| Martin’s Beach | Feeding on whale carcass | Sammy Rigling (Drone footage) |
| Santa Barbara | Stalking paddle boarders | ABC News |
| Aptos | Proximity to surfer | Local reports |
What Should Beachgoers Know About Shark Safety?
While sightings are increasing, authorities emphasize that these interactions are part of a natural ecosystem. Experts suggest that swimmers and surfers stay aware of local advisories and avoid areas where marine mammal carcasses are present, as these act as primary attractants for sharks. If a shark is spotted, the recommended action remains exiting the water calmly and immediately.
Frequently Asked Questions
Are shark attacks becoming more common in California?
While sightings have increased due to environmental factors, experts note that actual human-shark conflicts remain statistically rare even as predator populations utilize more of the coastline.

Why do sharks feed on whale carcasses?
Whale blubber is a high-calorie food source. Great whites often utilize these “underwater buffets” to sustain themselves during long migratory periods.
What should I do if I see a shark while surfing?
According to safety officials, remain calm, keep the shark in sight, and move toward the shore or a boat without splashing excessively.
