Your reason for asking if there are great white sharks in in Long Island Sound, maybe because you are worried about coming into contact with a great white shark when swimming on one of the Long Island beaches.
On the other hand you may like the idea of seeing one of these magnificent creatures. If you would like to see a great white shark close-up, see below about booking on a liveaboard from Mexico or on the MV Horizon liveaboard that leaves from San Diego to cage dive with great white sharks.
There are definitely great white sharks in Long Island Sound, as white sharks tracked by Ocearch shows that three of their tagged white sharks have visited the sound, including Cabot, Montauk and Scotia. The last ping of a tracked great white shark in Long Island Sound was on 18th October 2019.
The reason why Long Island Sound is visited by great white sharks is because the water temperature stays above 14.8°C (55.8°F) in May through to 14.6°C (56.8°F) in November, with a high of around 24.7°C (74.9°F) in August time. The sea temperature in the sound drops to below 12°C (56.8°) in December through April.
Great white sharks prefer water temperatures between 12-24°C (54-75 °F), which means they may visit Long Island Sound between the months of May and November each year when water temperatures in the sound are within this range.
The white sharks won’t be feeding on the harbour seals that migrate to Long Island Sound, as the seals leave the sound for Canada and Maine in March before the waters warm up, and then they return to the sound in December when the waters are too cold for great white sharks.
However, the great white sharks will be feeding on bait fish such as the Atlantic menhaden fish, which is now a protected species after a bill was signed to protect it against the fisheries. This has meant a rise in the number of white sharks off the east coast of America that often migrate down the east coast of America past Florida and into the Gulf of Mexico.
If you would love to dive with great white sharks, one of the best ways to do this is to book yourself on a scuba diving liveaboard that visits Guadalupe Island in Mexico. You can check the latest and best deals on liveaboards using the following window:
