Puget Sound and the San Juan Islands are very day sail and week end friendly..Or spend the summer...Lots of anchorages and several marinas and small dockages or public mooring balls. Tides are bigger then yours but currents you should be use to for the most part...but can run 6 to 7 knots in places... Good weather July thru Sept ( Most of the time) 70 to 85 degrees on the water. Can be crowded on week ends at prime locations...but there is always the off beaten gunk holes.
Check this site out for a pretty good write up on what to expect.
