Try a new spot. I have some real favorites, but if I show up and I don't see signs of action (especially this time of year) I leave.
This is the time of year to catch lots of fish real quick. They will be moving in big schools, and surfacing. The problem with that is they won't be in the same spot they were in the summer.
You will either catch 10 or catch 0.
Try looking for some new spots. Look for seagulls hovering over, or crashing into, the water.
Cast to the boils and catch 10.
