I fished the island once back in 1998 and I don't have much to offer access-wise. But what I can tell you to get your juices flowing, is that I went 4th of July - July 10 and the fishing was good... with several fish in 20's... but everyone I talked to said that the best weeks had been the 2 previous. Who knows if it will pan out that way... but a pretty good rule of thumb if you're gonna try a new destination in RI or MA June is the month to do it. You should do well. We fished "Surfside" and around the airport... also Madaket. Hope I'm not spot burning here... I think that's general enough
