Weather buoy 45005 is the most accurate way I have found to tell current wave conditions (when DOUBLED). From my experience this season so far, that is verrrry accurate. Thanks for sharing that with me earlier this year guys.

The rule of 1ft for every 5mph of wind is accurate enough as a starting point, but is very dependent on the wind direction and where you plan to fish. 12mph wind out of the east or northeast can churn up 3-4ft'ers when not knocked down by an island or peninsula. 12mph winds out of the south seem to usually only kick up 1-2ft'ers.
