How risky is a shark bite?

The International Shark Attack File investigates reports and classifies incidents rather than treating every rumor as equivalent. Its 2025 summary confirmed 65 unprovoked bites worldwide. That count can vary year to year and should be compared with the enormous number of beach visits and ocean recreation events occurring over the same period.

A population-wide probability includes people who never enter the ocean, while a surfing-hour rate requires reliable participation data that many places do not collect. Comparing sharks with lightning or household accidents can provide perspective, but the denominator, geography and time period must match before the numbers become analytically useful.

Encounters concentrate where sharks, natural prey and people overlap. Murky water, dawn or dusk, nearby schooling fish and fishing activity can change local conditions. Surfers spend more time at the surface and may enter zones with breaking waves and baitfish. Those patterns explain more than the idea of sharks deliberately hunting humans.

Follow local beach guidance, avoid swimming near active fishing or visible bait schools, stay with a group and leave the water calmly if large predators or unusual fish activity appear. These are proportionate precautions for a rare wildlife interaction. Fear-driven culling can harm ecosystems and does not substitute for location-specific evidence.
