In June, the U.S. Geological Survey placed a floating buoy just outside the swim line at the beach at Weirs Beach that monitors the water for bacteria, water quality, temperature and other conditions.
You can access the temperature info 24/7 :
https://www.usgs.gov/news/buoy-popul...ay-out-water-0 by going to the WaterQualityWatch link at the bottom, and then clicking on the small triangle spot in the center of New Hampshire, on the map. The water temperature is reported in degrees celsius, which is simple to convert with the internet ........ no more 'multiplying by 9/5 and add 32 = fahrenheit.'
At the moment it is reporting a water temperature of 24.3 c which is 75.74-degrees fahrenheit.
