Did you know… Along with the weather, Lake Tahoe is warming up?

Ryan Salm/Sierra Sun file photoLake Tahoe has been warming over the past 40 years, peaking at a highest-ever 78 degrees in 2006.

Over nearly 40 years the UC Davis Tahoe Environmental Research Center has kept track of conditions both above and below the surface of Lake Tahoe.

Over that time, Tahoe City nighttime lows have gone up by more than 4 degrees Fahrenheit, while the number of days with average air temperatures below freezing has decreased by 30 per year.

The combined effect means precipitation has increasingly fallen as rain instead of snow, with 34 percent now falling as snow, compared to 52 percent historically.

On the water, Lake Tahoe’s average surface temperature has risen by more than 1 degree over the last 35 years, reaching 52.6 degrees Fahrenheit in 2006.

The highest-ever recorded surface temperature was on July 26, 2006, when Tahoe’s shallow water registered a balmy 78 degrees.
