Most surfers will never see a shark in the water, even after years of regular sessions. The vast majority of shark encounters go completely unnoticed because sharks pass beneath or near surfers without surfacing, and surfers have extremely limited visibility from their boards. When actual bites do occur, surfers and board sport participants account for about 32% of unprovoked shark incidents worldwide, but with only around 65 confirmed unprovoked bites globally in a typical year, the raw numbers are tiny relative to the millions of surf sessions happening annually.
That said, “seeing” a shark and “being near” a shark are very different things. Research using drones and underwater cameras has repeatedly shown that sharks swim near surfers far more often than anyone on a board realizes. What surfers actually want to know usually breaks down into a few practical questions: how likely is an encounter, where and when is it most common, and what do sharks actually do when they’re nearby?
How Often Bites Actually Happen
The International Shark Attack File, maintained by the Florida Museum of Natural History, is the most comprehensive global database of shark incidents. In 2025, the United States recorded 25 confirmed unprovoked bites, and Australia recorded 21. Florida alone accounted for 11 of the U.S. cases, with Volusia County (home to popular surf spots around New Smyrna Beach) responsible for more than half of Florida’s total. Globally, the yearly total of unprovoked bites typically lands between 60 and 80.
Surfers and people on boards make up roughly a third of all bite victims. That’s partly because surfers spend long periods in the water, often in areas where sharks feed, and partly because of how surfers look from below (more on that shortly). But even at 32% of global incidents, that translates to roughly 20 to 25 surfer bites per year worldwide. For perspective, tens of millions of ocean recreation sessions happen annually in the U.S. alone.
Sightings vs. Close Passes
Visual sightings from a surfboard are rare because conditions work against you. Glare on the water surface, murky water (especially after rainfall), and the low vantage point of sitting on a board all make it nearly impossible to spot a shark even a few feet below. Queensland’s SharkSmart program specifically advises surfers to stick to clear water with good visibility, but even in clear conditions, a shark cruising at depth is effectively invisible.
Drone studies off beaches in Australia, California, and South Africa have captured footage of sharks swimming within meters of surfers who had no idea anything was there. These studies consistently show that close passes happen orders of magnitude more often than sightings or bites. The takeaway is straightforward: if you surf regularly in shark-inhabited waters, sharks have almost certainly been near you. You just didn’t know it, and nothing happened.
Where Encounters Are Most Common
Geography matters enormously. Florida’s warm, murky nearshore waters are home to abundant blacktip, spinner, and Atlantic sharpnose sharks, which accounts for the state’s consistently high bite numbers. Most Florida bites are minor, often involving small sharks in shallow water with poor visibility. Southern Australia and the eastern U.S. coastline have both seen shark encounter rates roughly double over the past 20 years, though absolute rates remain low.
In highly populated coastal regions like eastern Australia and the U.S. East Coast, the combination of growing human populations in the water and recovering shark populations has pushed encounters upward since the 1990s. Three of the unprovoked fatalities in 2025 involved white sharks biting surfers in Australia, and researchers have noted increasing numbers of white sharks at aggregation sites near popular Australian surf beaches. Hawaii also shows a noticeable upward trend in encounter rates over recent decades.
Countries with smaller coastal populations sometimes show higher per-capita attack rates, but the actual numbers are small and fluctuate widely from year to year. The places where surfers are statistically most likely to see or encounter a shark are the places with the most surfers and the most sharks sharing the same water: Florida, eastern Australia, South Africa, Hawaii, and parts of California.
When Sharks Are Most Active Near Shore
Time of day and season both influence how likely you are to share water with a shark. Dawn and dusk are the highest-risk windows. Sharks rely on vision to detect prey, and the dim light of early morning and late evening creates conditions where misidentification is more likely and where many shark species actively hunt.
Seasonally, patterns vary by region. White sharks in the Gulf of Maine and along Cape Cod typically appear from early summer through fall, with activity peaking in August. In Florida, blacktip sharks migrate south along the coast in winter, creating seasonal spikes. In Australia, white shark activity near popular beaches has been increasingly concentrated at known aggregation sites during warmer months. Water temperature plays a role in shark distribution, though researchers caution that warming oceans aren’t the sole driver of increased sightings.
What Sharks Do When They’re Close
This is where the science gets reassuring. The overwhelming majority of close passes result in nothing. Sharks investigate, lose interest, and move on. Even when a bite does occur, the pattern is telling: white sharks typically bite once and release. With their natural prey (seals and sea lions), white sharks strike, retreat, and wait for the animal to weaken before returning to feed. With humans, the shark almost never comes back after the first contact.
A 2021 study published in the Journal of the Royal Society Interface tested the long-hypothesized “mistaken identity” theory using a model of shark vision. Researchers found that from below, the visual profile of a person paddling a surfboard is statistically indistinguishable from a seal when processed through a white shark’s visual system. The silhouette, the motion patterns, and the shape cues all overlap. This doesn’t mean every shark bite is a case of mistaken identity, but it provides the first direct evidence that when white sharks target surfers from below, they may genuinely not be able to tell the difference.
Other possible explanations for bites include simple curiosity (sharks lack hands and use their mouths to investigate unfamiliar objects) and defensive behavior. But the fact that sharks so rarely follow through on a bite strongly suggests they aren’t treating humans as food. For the surfer sitting in a lineup, this means the shark that swam past you last Tuesday probably identified you as “not food” and kept going without you ever knowing it was there.
Practical Factors That Change Your Risk
Several things shift the odds of a visual encounter or a close pass. Murky water after storms brings sharks closer to shore to hunt disoriented fish and reduces your ability to see them. River mouths and inlets concentrate baitfish, which concentrate sharks. Surfing alone removes the safety buffer of other people in the water and eliminates the chance that someone on the beach spots a fin.
Your location in the water matters too. Sitting in a lineup farther from shore puts you in deeper water where larger species patrol. Surfing near seal colonies, especially in regions with white shark populations, meaningfully increases the chance of an investigatory approach. And surfing during the twilight hours combines reduced visibility with peak shark hunting activity.
None of these factors make a shark encounter likely in absolute terms. They shift an already tiny probability slightly higher. The most honest answer to “how often do surfers see sharks” is: almost never visually, probably more often than they’d like to think about in terms of proximity, and with vanishingly rare consequences either way.
