I'm on a 3 day out of Cisco's from 6/12-6/15, with a new moon on the 13th. What are my WSB chances? 100% better than if you stay on the beach. The best time to go they just whenever you can. There are other factors to increase your success rate. Like a boat and crew that fish them seriously. The 3-day trip is obviously going to improve your odds further still. I would say you are going at the right time. Check with the landing office or the boat crew and ask what their potential plans are for that trip. Best of success to you and the boat.
