Re: When is the wind speed too much?
That is a pretty good explanation of waves vs swells etc. Where I was saturday, at some time less than 1/4-1/2 mil from shore, the mid 20 knot winds had no waves per say. Meanwhile when we went out around west point......2-3 footers as the waves had time to build some. Went I went north to home some 12 miles farther, I was getting 3-4' waves with the same wind speeds.
If any of you have a chance to drive across a literal floating bridge, like I do across Lk Washington, amazing that in a 30-40 knot wind what the windward side is like, the next 100 yds to the other side, one could waterski across the lake! You get a really good feel for what fetch or distance will do for waves/swells. Meanwhile 6 miles or so north o 520 where I grew up along the lake, we had 2-3' waves, a mile north at the end of the fetch, sometimes 3-5 as the depth went from 100-200 to 20', so the waves/swells built up, such that even swells have waves. I also had that saturday evening too. Not sure how deep I was, as typically in puget sound it is 300-500', many hrs spend with NO depth registering on the depth guage, ie over 600'.
Then add in a 3-4knot current against the wind, waves are short and steep, tide/current with the wind, waves are longer, many times shorter in height, and one can tell when the tide/current changes, just by wave changes!
