Unprecedented Ocean Temperatures

Satellite data reveals that sea surface temperatures around Florida have reached record highs. This alarming trend is occurring earlier in the year than usual and can be attributed to the human-induced climate crisis, which is exacerbating extreme weather events.

In July, the surface ocean temperature around the Florida Keys soared to a staggering 101.19°F (38.43°C), potentially setting a global record for ocean heat. A water temperature buoy located in the waters of Manatee Bay at Everglades National Park recorded this scorching temperature, with nearby buoys also registering temperatures in excess of 100°F (38°C) and the upper 90s°F (35-37°C).

Climate Change & Anomalous Temperatures  

These extreme temperature readings deviate significantly from the normal water temperatures for this time of year, which should typically range between 73°F and 88°F (23°C and 31°C), according to the National Oceanic and Atmospheric Administration (NOAA). To put it in perspective, the level of heat recorded in July was akin to that of a hot tub.

As Florida grapples with these unprecedented ocean temperatures, it serves as a stark reminder of the profound impact of climate change on our planet. While the state’s beaches remain a beloved destination for sun-seekers, the warming of its waters underscores the urgent need for global efforts to mitigate climate change and protect our natural environments for future generations to enjoy.
