Find a public fishing pier.
http://wdfw.wa.gov/fishing/piers/Finding good jigs can be tough. The fat plastic ones from Big 5 don't work AT ALL. The ones that do well are usually thin, made of lead and are painted with a sparkly, glow in the dark paint and the hooks are more squared off, rather than looking like a V. I usually use 2, spaced about a foot apart. You can have up to 4, but more than 2 has a tenancy to get tangled up. For me anyway.
I'd take a picture of mine, but they were stolen by an octopus last week. True story.
If the pier has electrical outlets, get a shop lite from an auto parts store for like 20 bucks. point it at the water in the most focused beam it can make. Don't worry about fishing right in the light. I usually like to do it right outside the light. Squid have huge eyes and I like the jigs to be just visible, but not so illuminated that they can see the hooks and line.
Fishing the incoming tide seems to work best, but it's not vital. Cloudy weather seems to work best, but it's not vital.
I like to go almost to the bottom and give it a couple cranks every few jigs. When they aren't schooled up, they can be at any depth. So it's good to vary. When they are schooled up, they will be at ALL the depths, and then its a matter of how many you can get before they move on.
Happy hunting. You've got a good 2 months left in the season.
