Science Like a hot tub: Water temperatures off Florida soar over 100 degrees, stunning experts

On Monday, as much of the country stewed in bubbling heat, a boiling milestone was hit — a buoy in Florida registered a jaw-dropping 101.1 degrees Fahrenheit water temperature.

This was on the heels of the same buoy in Manatee Bay registering 100.2 degrees on Sunday. For perspective, the average hot tub temperature is 100-102 degrees F.


While the readings would've been considered a possible outlier or sensor error, surrounding buoys recorded similarly high temperatures, with 99.3 F at Murray Key and 98.4 F at Johnson Key.

Another reason why these water temperature readings are being taken seriously is the fact that experts have been tracking the exceptionally warm water temperature readings that have ranged from 92-97 degrees since early July.

For the majority of the month, an unusual weather pattern for the summer months for the region has been the driving factor. That pattern has featured a stagnant set-up fueled by a strong area of high pressure that has led to days of above average, and in many cases, record-setting air temperatures.

The pattern has also led to weaker than average trade winds. Trade winds usually produce southeast winds and a sea breeze for south Florida, which helps to keep the sea surface temperatures in check. Instead, winds have been out of the west and weak, allowing sea surface temperatures to heat up.

Still, despite a month of record-setting water temperatures already in the history books, Sunday and Monday's 100-degree water temperature reading stunned experts.

Factors that could have played a role in spiking the water temperature above 100 degrees include:

• Air temperatures in the mid-to-upper 90s.
• Weak winds across the region of less than 10 mph.
• Strong sunlight hitting shallow water, which heats up faster than deep water.
• Silty water leading to darker color, causing more absorption of sunlight and additional heating. Think of clear water vs. murky water as being similar to cement vs. asphalt. The darker the color, the more absorption and hotter the temperatures.

The water temperatures recorded Sunday and Monday would challenge the record for hottest sea surface temperature in the world. While official world water temperature records aren't kept, a 99.7 degree temperature recorded in Kuwait Bay is considered the world record at this time. Due to factors like proximity to land and the silty nature of the water, the temperatures recorded off Florida would have to go through an extensive verification process.

According to the National Oceanic and Atmospheric Administration (NOAA), ocean warming since 1991 doubles the size of the marine heat wave forecasted for September 2023.


According to the experimental forecast issued in June, 50 percent of the global oceans could experience heat wave conditions by September.

The forecast system also estimates how large and intense heat waves are without global warming’s influence on the ocean over the past three decades. Without the warming effect, the models predict that only 25 percent of the global ocean will be affected by heat waves in September.

Water temperature is what fuels hurricanes. The hotter the water, the stronger the hurricane.

Yep--104 for us as well.

 

That's pretty old. Consider replacing it.
