Boat water temperature recorded using Airmar through-hull transducer/thermometer connected to Northstar 962 chart plotter. Approx. 2 feet below waterline.

It was a beautiful day on the harbor for the Boston Light Swim. Our early start time meant that there were very few pleasurecraft on the water until later into the swim. When we arrived at the starting area, there was a bit of surface chop on the water. Water temperature at 65 degrees was not an issue for most swimmers. As the race progressed, the water surface conditions improved, and the water became smoother. As the flotilla passed under the Long Island Bridge and towards Thompson Island, there was an increase in boat traffic, with some increased wave action from boats. Winds were generally calm all morning.

Thanks to the Goast Guard, Boston Police, and Coast Guard Auxiliary that were on the water helping to establish a safety perimeter around the swimmers.
