I use this page for the marine forcast : http://www.wunderground.com/MAR/lmm.html. Click on the section of Lake Erie you want to fish. sometimes this isn't super acuate. but what i did find on this, is after you click on the section, look to lower right side of the page and they have they the bouy information. The first one is for Port Colbourne. Look at the actual wave height for it. Thats usually a good gauge.
