About the marine forecast for Plum Island Sound (south end)

This is the National Weather Service forecast for Plum Island Sound (south end) (Massachusetts), covering wind, wave height, temperature, and conditions over the coming week.

Remember that gusts, not the average, are what knock you around, and that wind blowing against the tide stacks the seas up steeper than the numbers suggest.
