Warming Oceans Drive Unusual Marine Life to Massachusetts Coast

According to a report published on August 15, 2025, the waters around Massachusetts have been steadily warming due to the ongoing effects of climate change. This warming trend has led to a number of unusual sightings and health advisories along the state's coastline.

Colleen Bowie, a longtime visitor to Revere Beach, has noticed significant changes to the area over the years. "It's still beautiful, we're lucky to be here," she said. "But I wish it wasn't changing so much."

Researchers have confirmed that this summer's ocean temperatures in Massachusetts are part of a clear climate change pattern. The warmer waters have allowed new species to migrate northward and created conditions for harmful bacteria and algal blooms to thrive.

Just earlier this month, a manatee was spotted in Mashpee, a rare occurrence this far north. Additionally, an alert was issued in Falmouth about vibrio vulnificus, a flesh-eating bacteria typically found along the Gulf Coast. "The idea that you would see a manatee is just nuts," said Dr. Kristina Dahl of Climate Central.

The warming trend is also driving traditional Massachusetts marine life, such as cod and lobster, further north in search of colder waters. "One of the remarkable things is just how quickly the oceans are changing," said Glen Gawarkiewicz, a senior scientist at the Woods Hole Oceanographic Institution.
