About the marine forecast for Prospect Harbor

This is the National Weather Service forecast for Prospect Harbor (Maine), covering wind, wave height, temperature, and conditions over the coming week. Wind and seas are what make or break a day on the water, so start there. 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. Wave height here is the significant wave height, so some individual waves come through taller.
