The scorching heat affecting parts of Florida this week has also led to warmer ocean temperatures, which hit record levels around the state’s coasts last year. While hot water can herald a busy hurricane season, it also reduces the enjoyment of beach activities, as 90- to 100-degree water offers little refreshment.

Current Ocean Temperature Trends in Florida

As of now, water temperatures in Florida haven’t reached dangerously high levels, though some areas are already seeing surface temperatures approaching 91 degrees. For instance, on July 9, 2024, Apalachicola in the Florida Panhandle and Long Sound near the Florida Keys recorded ocean surface temperatures at 90.9 degrees. Last year, it wasn’t until mid-July that South Florida waters hit 100 degrees. Despite these high readings, many beaches across the state still have ocean temperatures in the mid-80s, making them more suitable for swimming.

Risks of Swimming in Hot Water

Swimming in excessively warm water can be hazardous. According to a report from Livestrong, water temperatures exceeding 90 degrees can lead to overheating and exhaustion. “Warm water increases your body temperature, which also raises your sweat rate and quickens dehydration,” the report explains. “Open-water swimming in warm climates can expose you to water temperatures that are too warm, causing muscle spasms and severe fatigue.”

The Consumer Product Safety Commission (CPSC) also warns against the dangers of hot water immersion. According to the CPSC, water at 106 degrees Fahrenheit is unsafe for humans to submerge in. “Soaking in a hot tub with water heated to 106 degrees Fahrenheit can raise human body temperature to the point of heat stroke or impair the body’s ability to regulate its internal temperature,” the CPSC report states. “These conditions can be fatal even to fully healthy adults.”

Historical Records and Safety Concerns

In July 2023, a buoy south of Miami recorded ocean water at 101.1 degrees Fahrenheit, more than 11 degrees hotter than what is considered safe for swimming. Such extreme temperatures are not only uncomfortable but pose significant health risks.

The increasing frequency of high ocean temperatures is a concern for both safety and enjoyment. As temperatures continue to rise, swimmers need to stay informed and cautious. Monitoring local water temperatures and understanding the risks associated with warm water swimming can help prevent heat-related illnesses.

Beachgoers are advised to be mindful of current water temperatures and avoid swimming in excessively warm waters to prevent overheating, dehydration, and other heat-related conditions. With proper awareness and precautions, it is still possible to enjoy the beautiful Florida coastlines safely.
