If you are there only one night - and I have to assume it will be next Thursday as you said next and not today. You are going to have a 4:09 +- am high tide. Loose the sleep and fish that tide right in front of the Blues. There is a rocky breakwater there and you can toss a live eel there and catch a biggie. PI has been slow, but it is due to open soon.
Beach at high tide -- river at low tide, the river is swift but productive
Kay is the Guru of PI and will steer you right.
Good luck.
