Default Water temp???

Safe to assume the lack of posted water temp change herein means it's still about 78? It seems to be pretty close to where it was earlier this month, even with the rain. We saw 76 on Sunday at our friends' on Camp. anybody seeing much different?

Exclamation ..... 82-degree, Aug 6 surface water, all time high?

August 6, 2018: 82 degree Lake Winnipesaukee surface water temp, according to Barney Bear on Bear Island, is the all time record high from what I know. See the other Water Temp-2018 thread in the General Discussion section.

Usually, the high is from 76-78, and in 1998 it got up to 80 due to high air temp combined with little to no rain that made for relatively low lake level.

Looks like this summer, it was high air temp and little to no rain had it up to 82. Is possible it even got maybe higher?

Is too bad the U.S. Geological Survey solar powered monitor buoy stationed just outside the swim line at Weirs Beach swim area, depth about eight feet with sandy bottom, in 2016 and 2017 was not in use in 2018 and not used this summer on Lake Winnipesaukee. That would go a long way to verifying, and making it a believable number. The USGS monitor buoy measured water temperature down to hundreds, for example 82.13, along with the water ph, and other measures.

Recall reading somewhere the USGS has an annual budget over one billion dollars, (Wikipedia).

https://www.pwd.org/news/new-sebago-...rch-and-public ....... May 16, 2018: Lake Sebago in the great state of Maine gets a 145-lb, solar powered, water monitor buoy ..... with 1:07 video of buoy deployment by Portland Water District.

So, maybe the NH-DES could get the same buoy for Lake Winnipesaukee ...... like, why not?

The water temperature at East Bear Island is 77 degrees 18" below the surface. Our guests from Japan have raved about our beautiful, special lake. 🇯🇵

Besides air temperature, humidity has a big effect. High dew point air (humid) retards evaporation, which has a cooling effect. When a dry air mass comes in with some NW wind behind it, the surface temperature drops notably.

Water temp is 10 degrees warmer than this time last year. Reading 78 on my chart plotter (1’ deep but air is cooler) all across area north of Cow today. Still above my swimming threshold.....isn’t this September?

Pretty sure the warmest lake temp is usually the end of Aug/beginning of Sept.

They didnt have thermometers in 1822 but I'm probably wrong and mid August would be more like it.

I've got a model of Galileo's "thermometer"—invented in 1593. Not a mercury thermometer, I feared it might freeze and break in our unheated cottage last winter. It came through OK. It uses mineral spirits as a suspension medium. Some "Galileo thermometers" sold today don't recommend freezing temperatures.

I think the weather has changed. It seems the last couple of weeks of August used to be windy and a bit cooler but it doesn’t seem that way any more.
