October has not been to good to us the last couple of years and we're thinking about switching it up, any opinions?

When you can!

The Block in the fall is not anywhere near what it was in the 80s. DZ still finds quality fish in Nov but even he will admit that it is a shadow of what it once was. I don't know why either.
I I have hear that the Spring can be good.

I use to fish the Block every Fall religiously. Stopped 3 years ago when I had 5 years in a row with few and no fish.

If I were to make a long run in the Fall in the surf I think I would do Cutty or Montauk.

IMO , Montauk is better in late nov. I would still choose Block island over montauk in October.

June 25th-July 10th with the week of the July 4th being the best.

I used to have great results at the end of October back in the early 90s. Weekend of July 4th was reserved for the drunkfest.

when the fish are there, which is few and far between, September

June 25th-July 10th with the week of the July 4th being the best.

When I was w/o boat, I had a few conversations with Capt Mike Neto regarding fishing BI. He always recommended the same time frame, especially July 4th weekend out there.
