Chuns Reef, Oahu, Hawaii Shark Attack - February 25, 2026 | All Information

SafeWaters.ai is investigating a shark encounter that occurred on Wednesday, February 25, 2026, off the North Shore of Oahu, Hawaii. A surfer sustained significant injuries to his left leg after an apparent shark bite. The incident has prompted immediate beach closures and increased aerial patrols in the area, advising caution for all ocean users.

What Happened

At approximately 10:45 AM HST, Mr. David Chen, 38, a local resident and experienced surfer, was reportedly surfing about 75 yards offshore from Chun's Reef. According to witnesses and Mr. Chen's account, he was paddling back out after catching a wave when he felt a sudden, powerful impact and a searing pain in his left leg. He described seeing a large, dark shape in the water before he was pulled under briefly. Mr. Chen managed to paddle aggressively back to shore, alerting other surfers and beachgoers to the presence of a shark. Emergency services were immediately called, and paramedics arrived within minutes to provide first aid.

The bite caused deep lacerations and significant tissue damage to his lower left leg, just above the ankle. Lifeguards quickly established a perimeter, hoisted shark warning flags, and began clearing the water. Police and Department of Land and Natural Resources (DLNR) officials are on the scene, conducting an investigation and assessing the situation. This incident marks the first confirmed shark bite on Oahu's North Shore for the year 2026.

Location Details

The incident occurred off Chun's Reef, a popular surf break located between Waimea Bay and Haleiwa on Oahu's North Shore. This area is well-known for its consistent winter swells and diverse marine life. The ocean conditions at the time of the incident were moderate, with waves in the 3-5 foot range and good visibility. Water temperature was approximately 75°F (24°C). The presence of baitfish, such as ʻōpelu and akule, is often noted in the area, particularly following periods of heavy rain or strong currents, which can attract larger predatory fish. Recent reports from local fishermen indicated an increase in schooling fish activity in the days leading up to the incident.

Shark Species Involved

While the exact species of shark involved has not been definitively confirmed, based on witness descriptions of the size and attack pattern, along with the nature of the injuries, experts from the Hawaii Institute of Marine Biology suggest a tiger shark (Galeocerdo cuvier) or a Galapagos shark (Carcharhinus galapagensis) as the most probable culprits. Both species are commonly found in Hawaiian waters and are known for their territorial behavior. Further analysis of the bite marks will be conducted by marine biologists to provide a more precise identification. It is relatively uncommon for sharks to directly target humans; such incidents are often a case of mistaken identity, especially in murky waters or at dawn/dusk.

Victim Condition

Mr. Chen was transported by ambulance to Queen's Medical Center in Honolulu. He underwent emergency surgery to address the extensive injuries to his left leg. Hospital spokespersons have confirmed that he is in stable condition, but faces a long recovery period. His family has requested privacy during this time. Medical staff are optimistic about his prognosis, emphasizing that timely first aid played a crucial role in preventing further complications.

Historical Context

Oahu's North Shore has a history of shark encounters, though serious incidents remain relatively rare compared to the number of people who use the ocean recreationally. The last confirmed unprovoked shark bite on the North Shore occurred in April 2024, involving a paddleboarder near Laniakea. Hawaii as a whole averages around 4-6 unprovoked shark bites per year, with a significant percentage resulting in non-fatal injuries.

How to Stay Safe

In light of this recent incident, SafeWaters.ai reminds all ocean users to exercise extreme caution and adhere to these safety guidelines:

• Avoid swimming or surfing at dawn, dusk, or night when sharks are most active.
• Do not enter the water if you have an open wound or are bleeding.
• Swim, surf, or dive with a buddy, and stay close to shore.
• Avoid murky waters, river mouths, or areas with significant baitfish activity.
• Heed all shark warning signs and lifeguard directives. If a beach is closed, stay out of the water.
