Shark sightings have increased along the southern Maine coast this summer, prompting officials to urge beachgoers to use caution. Several white sharks were recorded on video near beaches in Scarborough and nearby areas. Researchers say the reports may reflect both a recovering shark population and the growing use of drones, mobile phones and social media to find and document sharks. Warmer ocean conditions and abundant prey could make sightings more common in the future.
Reports began arriving frequently in early July, with sharks first seen near Pine Point Beach before moving toward Scarborough Beach State Park and Higgins Beach. Officials said sightings continued daily for roughly three weeks as of late August.
Marine scientists caution that more reports do not necessarily prove that the total number of sharks has sharply increased. Better beach weather, heavier tourism and improved technology have made sharks easier to spot and record than in previous decades.

Sightings spread across southern Maine beaches
Scarborough officials began receiving numerous reports in early July. Several sightings were captured on video, and sharks remained near Pine Point Beach for a substantial period. By late August, reports had shifted toward Scarborough Beach State Park and Higgins Beach, where officials said sharks were still being observed daily.
The reports involved white sharks, including juveniles, in waters used by swimmers and other beachgoers. Residents described the frequency as unusual compared with their past experiences.
Weather and technology increase reports
Researchers said reported sightings are shaped by who is on the beach and how actively people are searching. Favorable weather brought more visitors near the water. Photographers, beachgoers and law enforcement also used drones to scan the coast, while phone video and social media amplified individual sightings.
Those factors make comparisons with earlier decades difficult. People did not previously search for sharks with the same intensity or aerial equipment. Scientists said the increase in sightings is clear, but determining whether it represents a larger shark population requires a more nuanced assessment.
“There’s no question that there’s been a lot more sightings this year. Does that translate into a higher number of sharks is a little bit of a nuanced question.”
Protections and prey support white sharks
Researchers said white shark numbers have been recovering gradually for decades after federal protections were established in the 1990s. Maine’s seal population has also grown, creating a more reliable food source. The recovery could indicate that the white shark population is approaching a more natural level after years of depletion.
Juvenile white sharks have access to bait fish along the Maine coast, including striped bass and Atlantic menhaden. These conditions may help explain why young sharks appear closer to shore. The return of an apex predator is considered an ecological success because it can help restore balance in the marine food chain.
Warming waters may extend the season
Scientists said rising ocean temperatures could eventually allow white sharks to remain in the Gulf of Maine for longer periods. If that trend continues, frequent sightings may become a more regular feature of the southern Maine coast rather than a short seasonal event.
Future sightings will depend on water temperature, prey distribution, shark age and the movement of seals and bait fish. Researchers have not said warmer water alone explains this summer’s reports, but they consider it a possible long-term influence.
Officials issue swimming precautions
Officials urge people to remain alert near reported shark activity. Recommendations include avoiding swimming alone, staying out of the water at dawn and dusk, and avoiding murky conditions where visibility is limited. Swimmers are also advised to remain in waist-deep water or shallower when possible.
People with open wounds should avoid entering the water, and swimmers should remove jewelry before swimming. Beachgoers are encouraged to pay attention to their surroundings and make decisions based on current conditions and location.
| Number | Key Point |
|---|---|
| 1 | Shark reports rose across Scarborough beaches during summer. |
| 2 | Weather, beach crowds and drones increased detection. |
| 3 | Protections, recovering seals and bait fish support white sharks. |
| 4 | Warming waters could keep sharks in the Gulf of Maine longer. |
| 5 | Officials recommend avoiding dawn, dusk, murky water and solo swimming. |
Summary
The increase in southern Maine shark sightings reflects a likely recovery of white shark numbers, more seals and bait fish, favorable summer weather and widespread use of drones and phones. The evidence does not establish that the population suddenly surged, but sharks are being detected more often near popular beaches. Officials urge swimmers to remain aware of conditions and follow basic safety measures.
Frequently Asked Questions
Where were the sharks seen?
Reports began near Pine Point Beach and later shifted toward Scarborough Beach State Park and Higgins Beach.
Why are more sightings being reported?
Researchers cited favorable weather, larger crowds, drone searches, phone video and social media, along with a possible recovery in the white shark population.
What safety steps should swimmers take?
Officials recommend not swimming alone, avoiding dawn and dusk, staying out of murky water, remaining in shallow water when possible and avoiding the water with open wounds.
Could sightings become more common?
Warming ocean temperatures could allow sharks to remain in the Gulf of Maine longer, potentially making regular sightings more common.
