On coastlines around the United States jetties are often used to protect harbor and inlet entrances. They are also some of the most dangerous waters for swimming. According to NOAA, jetties can contribute to increased drowning risks, especially due to the presence of rip currents and the potential for dangerous currents and changes in water depth near the structures. Jetties can also make it more difficult to enter and exit the water safely due to sharp rocks and the force of waves. 

The placement of jetties can alter water flow, creating areas with unpredictable and strong currents, making it difficult to swim or navigate. Jetties and even some piers can disrupt natural water flow and contribute to the formation of rip currents, which are powerful, fast-moving channels of water that can sweep swimmers away from shore. 

Many local jetties are made from rock, creating a risk on land. They become slippery, sharp, and dangerous. It can be very easy to slip on the rocks, as they are often covered with a layer of foam or a slick moisture coating. A slip on the rocks can lead to broken bones, head or other internal injuries.

Stay aware, while jetties have a purpose in protecting harbors and shorelines, they also create potential hazards for swimmers and beachgoers, including rip currents and changes in water depth, making them a place to be cautious around.

Let’s enjoy the beauty of our shoreline while also keeping in mind that we need to respect it as well.
