Water Temperatures In The Potomac At Little Falls Hit 94F 7/24 - A New Record High
The 12-day heat wave that just ended in Washington turned the Potomac River to veritable bath water.
On the river at Little Falls, Sunday’s 93.7 degree reading 4.1 feet from the shoreline is the highest on record in that location by a half degree and almost 10 degrees hotter than average (84.2 degrees). That temperature tops the highest mark of 93.2 degrees set in 2011 and 2012, two of Washington’s hottest summers on record. […]
As if the air wasn’t hot enough, the steamy water pushed humidity levels through the roof along adjacent shores. The heat index, a measure of how hot it feels factoring in the humidity, topped out as high as 115 to 120 degrees near the water’s edge.
Relentless heat over the past four weeks pushed water temperature this high, culminating in the hottest weather of the year this past weekend. […]
From 25 June 2019 to 22 July 2019, 23 days hit at least 90 degrees. Only 1977 saw more days (24) that hot in that time frame.
