Here is my take on gauging the launch from buoy readings, since everyone asks this
question at our FastLane Kayak Fishing Seminars ...

TCS hit it right on the nose. I would go as far as saying that swell PERIOD matters a
whole lot more than direction at the Shores launch. Any swell, whether its from 195,
210, 270, or 295, with a long swell period (>12 seconds) will have very little effect at
the launch.

Short period "wind swells" (< 8 seconds) are the problem, as they disregard the canyon's
refracting effects and swarm the launch area at very consistent intervals when they
arrive.

At Big Rock, where I launch generally, its precisely the opposite. This weekend will have
excellent launch conditions at both places. Bring the sunhat and sunscreen though,
summer is finally here!
