Just to throw my own observations of Sherman from this weekend.
I sailed the Access Sunday from 2-6pm. 2-4pm on 6.0m OP'd (175lbs.) and
4-6pm on a 5.0m.
The wind was SW and from the beach with a hand wind meter I read about
20mph at 2pm and about 25mph at 4pm. Checking with the COTW at those times
this measured about halfway between the Average and Gust measurements. I'd
say you can add another 5mph to all those readings as to the max gusts out
on the water.
It was my first time this year out on my 5.0m so I was quite happy I made
the trip from the peninsula.
Alex.

>Here are my observations about Sherman wind patterns:

>Spring:
>Where there are strong N/NW pressure gradients,
>windy cove and the jungle are good launches - the ideal is a flood tide
>for the best ramps vs. Ebb in summer. COTW is very accurate
>for NW winds at the delta.

>Summer:
>When the wind has a strong W component, the access
>will be better. When the wind has a strong S component,
>powerlines/the sign will blow a bit better.
>For dawn patrol, powerlines seems to blow about 30 min. longer
>The sign seems to have the best ramps - best direction and the
>biggest in size. For the PM session, the access seems to blow
>a bit more steady and earlier.
>
>When I do dawn patrol I use two data points. The first one is
>look outside my bedroom window - I live in the Oakland hills. If the
>fog is moving pretty fast and my chimes are ringing, the delta will
>be happening; skip other checks, get coffee and drive.
>If the fog is dense, not moving much and condensing
>on everything, not much wind is to be expected: back to sleep.
>The second data point that I use when the fog appears to be
>moving up high and my chimes are not ringing is to call the
>windtalker/look and COTW. If the top windspeed number is >20,
>get in the car and drive, else return to warm sheets/covers/body;-)
>
>I have been 95% right using this simple decision tree.
>
>Last night was solid 5.2/8'8" Enduro (207#) at the access. Nice ramps.

>Anyone hear any news on the levee project? I thought it was going to
>be started by now....Z
