Sounds like the AM boating is out for sure, at least it would be for
me. :-) Good day for a hot fire and a cold beverage ashore.

How much of your combined sea is a swell vs. wind wave when they're
running 16-19 feet?
I'm not well versed on your local conditions, but with only 15-25kt
winds it would seem like swells would predominate. At 16-19 feet, I
assume you're seeing the latent influence of the same storm that passed
through and generated those 50kt gusts. By way of comparison, what are
your typical summer swells and period outside of the gate?


Swells are without wind waves. They get thrown on top of the swell, but
sometimes are a different angle. Nasty then. Most of the summer is 3-8'
swells, and little wind until about 11:30 am. Most of the time, you get
your fishing done and head back in about 10:30. July is normally nicest
time. When you get the South winds, it is the worst. No shelter and the
Pt. Bonita area (North side of the Golden Gate at Lands End) gets really
sloppy.


As long as you're answering questions, what does 'dominant period of 13
seconds'
mean?

The time between crests. the closer together, the steeper, and nastier. 13
seconds, says they are really steep and nasty. In the summer we get 8'
swells with 20-24 second periods.


Thanks.
