I can't top Jay's post, so I'll just give you my two cents about the Plymouth
Nuke. It's a tough place to fish from the breakwaters due to crowding at this
time of year, but the fish are definitely hanging in the warm water outflow
pigging out on the bait attracted to the area. Drifted mackerel chunks and surface plugs
that don't bounce all over the place in big standing waves (like Ranger plugs)
are probably your best bet. Daytime fishing for blues is good from now to whenever
they leave for the season. Small stripers there now but bigger ones will mix in
starting consistently in September. I've seen a couple of nice blitzes here
(stripers and blues mixed) in September, with fish boiling in both the outflow
and on either side of the jetties.
Fishing from a boat will eliminate the jetty access
problem, but just watch out for the plugs, snagging hooks, and taunts hurled
from shore ;-)
