Florida’s Manatees Seek Warmth Amid Polar Vortex Chill
RIVIERA BEACH, Fla. — A recent polar vortex sweeping across the U.S. has brought icy conditions to much of the country, including a rare chill to Florida’s coastal waters. This sudden drop in temperature has prompted the state’s manatee population, still recovering from a devastating mass starvation event several years ago, to seek refuge in warmer waters.
Manatees, often referred to as “sea cows,” are highly sensitive to cold temperatures. When water temperatures dip below 68 degrees Fahrenheit, these gentle giants migrate to warmer areas to survive. While Florida’s natural springs are a popular destination, the warm-water outflows from power plants have become a critical sanctuary for these aquatic mammals.
Power Plants: A Lifeline for Manatees
For decades, manatees have been drawn to the warm-water discharges from about a dozen power plants across Florida. These locations, including Riviera Beach, Fort Myers, and Apollo Beach, have become essential habitats during the colder months. Mother manatees even pass down these migration routes to their calves, ensuring the survival of future generations.
One such hotspot is the manatee Lagoon, a free, two-story, 16,000-square-foot attraction opened by Florida power & Light Company in 2016. Located near the Riviera Beach power plant, the facility offers extensive viewing areas where visitors can observe dozens of manatees congregating in the warm waters.
“Manatees are such a special species that we have in our waters here in Florida,” said Rachel Shanker,education manager at Manatee Lagoon. “they are a sentinel species, which means they’re an indicator for any water problems or environmental issues we may have. they’re kind of the first animals to start to respond to any changes in the habitat.”
ManateeFest: A Party of Conservation
To celebrate these beloved creatures, manatee Lagoon is hosting a family-kind ManateeFest on February 1. The event will feature educational exhibits, interactive activities, and opportunities to learn more about manatee conservation efforts.

Why Manatees matter
Manatees are more than just a Florida icon; they play a vital role in the state’s ecosystem. As herbivores, they help maintain healthy seagrass beds, which are crucial for marine life. However, their reliance on warm-water outflows from power plants highlights the need for long-term conservation strategies, especially as natural habitats face increasing threats from climate change and human activity.
Plan Your Visit
If you’re eager to see these gentle giants in person, now is the perfect time. From November to March, manatees gather in large numbers at warm-water refuges, making it easier to spot them.Whether you visit Manatee Lagoon in Riviera Beach or explore other viewing areas, you’re sure to leave with a deeper gratitude for these remarkable creatures.
As florida’s manatees continue their recovery, every sighting is a reminder of the importance of protecting their habitats. So bundle up,head to a warm-water refuge,and witness one of nature’s most heartwarming spectacles.Florida Manatees Face Ongoing Threats Despite Slight Decline in Deaths
Florida’s beloved manatees, frequently enough referred to as ”sea cows,” continue to face notable challenges despite a slight decline in mortality rates in recent years.According to the Florida fish and Wildlife Conservation Commission (FWC), 565 manatee deaths were recorded in 2024, a figure similar to the 555 deaths reported in 2023. While these numbers are lower than the devastating 1,100 deaths recorded in 2021, the species remains vulnerable due to habitat loss, pollution, and climate-related stressors.
The Role of Seagrass in Manatee Survival
Manatees rely heavily on seagrass as their primary food source. Though, pollution from agricultural runoff, urban advancement, and other sources has led to widespread seagrass die-offs, particularly in the Indian River Lagoon, a critical habitat for these gentle giants.
“The center of those problems was in the Indian River Lagoon, where over the years, they’ve had these problems with all these algal blooms,” said Martine de Wit, an FWC manatee veterinarian. “And that affected the water clarity and quality, and seagrass had died off in that area.”
The Indian River Lagoon, located along Florida’s Atlantic Coast, is home to more than 8,000 manatees, with at least a third of the population living or migrating through this vital ecosystem. The loss of seagrass has forced manatees to travel farther for food, increasing their risk of starvation and cold stress.
Efforts to Save the Manatees
In response to the crisis, state wildlife officials launched an unprecedented effort to feed manatees lettuce temporarily. This intervention, combined with natural seagrass recovery, has contributed to the recent decline in manatee deaths.
“after two especially deadly winters, seagrass in the area began to recover, and manatee deaths have dropped,” officials noted.
the Impact of Cold Stress and Human Activity
While starvation remains a significant threat, cold stress and boat collisions are also major contributors to manatee mortality. During colder months, manatees seek out warm water sources, such as those discharged by power plants, to survive.
“So during the power generation process, that power plant puts out clean, warm water, and that warm water draws the manatees in when it gets cold,” explained Shanker, a spokesperson for Manatee Lagoon, a facility that provides a safe haven for manatees during winter.
The facility, open year-round, sees the highest number of manatees between November 15 and March 31, when water temperatures drop below 68 degrees Fahrenheit—a potentially deadly threshold for these marine mammals.
A Glimmer of Hope
Despite the challenges, there are signs of hope. The recovery of seagrass beds and ongoing conservation efforts have helped stabilize the manatee population. However, experts emphasize the need for continued vigilance to address pollution and habitat degradation.
“The manatees come here to Manatee Lagoon for that warm water, but we don’t have a large population of seagrass right here on our property,” Shanker said. “And so they’ll come here to get warm, then when they start to get hungry, they will travel out to find those seagrass beds, and they’ll go feed until they get full, and they get cold, and they’ll come back to our warm water to get warm.”

Florida’s manatees are a testament to the resilience of nature, but their survival depends on our collective efforts to safeguard their habitat and address the environmental challenges they face.Florida’s Manatees: A Story of Resilience and Renewed Challenges
Florida’s iconic manatees, often referred to as “sea cows,” are making a slow but steady recovery after years of hardship. However, their journey is far from over. Recent developments highlight both the resilience of these gentle giants and the ongoing threats they face.
The Seagrass Comeback and Manatee Recovery
Seagrass, the primary food source for manatees, has shown remarkable resilience. “seagrass is resilient, and it came back on its own, and manatees found it,” said de Wit, a key figure in manatee conservation efforts. This resurgence has been a lifeline for the species, which suffered a devastating seagrass famine in recent years.
The famine left many manatees so malnourished that they were unable to reproduce for several years. However, as seagrass beds began to recover, so did the manatees. “When the food returned, those previously starving animals all began reproducing at the same time,” de Wit explained.
This reproductive boom, while a positive sign, has also led to a spike in calf mortality. “When you have higher pregnancy rates, more manatees being born, you always have a proportion that does not make it,” de wit noted. “I think that was just a measure of the reproduction coming back after all those lean years as 2020.”
A Controversial Decision: Manatees Remain “Threatened”
Despite the challenges, the U.S. Fish and Wildlife Service recently rejected efforts by several Florida environmental groups to reclassify manatees as endangered. The species was downgraded from endangered to threatened in 2017, and it will remain in that classification for now.
this decision has sparked debate among conservationists. While the manatee population is recovering, experts warn that the species is not out of danger. “Florida’s manatee population is recovering, but officials and residents need to remain vigilant in protecting the threatened species,” de Wit emphasized.
Ongoing Threats and the Need for Vigilance
The future of Florida’s manatees is far from secure. “We always look into the future, and there are significant threats to manatees statewide,” de Wit said. “it’s looking better now, but you cannot sit back and watch it unfold, as we certainly know it needs management and conservation efforts to protect them.”
Key threats include habitat loss, water pollution, and boat strikes. These challenges underscore the importance of continued conservation efforts to ensure the survival of this beloved species.
