Hi Bill:
I'm no expert, but two things I've read about and observed seem to be true regarding conditions:
1. They like a moving tide. Slack tides seem to shut off the bite.
2. They don't like wind that ripples the surface. That seemed to shut them off as well. In coves where we had caught fish, if the wind was moving the water they wouldn't bite. So we'd move to coves out of the wind and we'd catch fish there.
Tight lines and let us know how you do if you get out again,
Jamie
