The water temperature on the tip of Florida hit hot tub levels, exceeding 100 degrees (37.8 degrees Celsius) two days in a row. And meteorologists say that could potentially be the hottest seawater ever measured, although there are some issues with the reading.
Just 26 miles (40 kilometers) away, scientists saw devastating effects from prolonged hot water surrounding Florida — devastating coral bleaching and even some death in what had been one of the Florida Keys’ most resilient reefs. Climate change has been setting temperature records across the globe this month.
Weather records for sea water temperature are unofficial, and there are certain conditions in this reading that could disqualify it for a top mark, meteorologists said. But the initial reading on a buoy at Manatee Bay hit 101.1 degrees (38.4 Celsius) Monday evening, according to National Weather Service meteorologist George Rizzuto. On Sunday night the same buoy showed an online reading of 100.2 (37.9 Celsius) degrees.
“It seems plausible,” Rizzuto said. “That is a potential record.”
While there aren’t official water temperature records, a 2020 study listed a 99.7 degree (37.6 Celsius) mark in Kuwait Bay in July 2020 as the world’s highest recorded sea surface temperature. Rizzuto said a new record from Florida is plausible because nearby buoys measured in the 98 and 99 (36.7 and 37.2 Celsius) degree range.
“This is a hot tub. I like my hot tub around 100, 101, (37.8, 38.3 Celsius). That’s what was recorded yesterday,” said Yale Climate Connections meteorologist Jeff Masters. Hot tub maker Jacuzzi recommends water between 100 and 102 degrees (37.8 and 38.9 Celsius).
