Dearman:I wasn't too fond of Edmonds, but it may have been my luck. The day before several divers saw a whale (grey I believe). The park itself doesn't get very deep (45'), so they must have gine past it. Mukilteo also has a site I'll dive this weekend. Alki beach is popular. There is a site out on Whidbey island. On the penninsula Cresent lake is fresh water that is supposed to be phenonimal vis. There are multiple shore sites along the San Juan straits. Tides can play a major factor. Check with a local shop. Many do day trips to the San Juans.
www.lighthousediving.com is the one I use.
I haven't dove most the sites, but you can find many people who have in the NW Orca Bait forum.
Edmonds can be a spectacular dive, but it is wind wave affected. Too much wave action kills the vis. Actually the whale I saw at Edmonds was a Minke whale, it's the second one I've seen this year(from the surface) at Edmonds. he was within the buoys just south of the Cathedrals so it was about 30 FSW. I've dove most of the sites in the Puget Sound and the Straits, (that I know of), but I'm always up for something new.
