I will go x2 on the no expert, however personal observation has water clarity, barometric pressure trends, and time of year playing a large part. I got into a good steady day bite last week in clear water just before a front moved in. We also have some lakes that are heavily stained with no night bite what so ever. Time on the water will get you up to speed real fast as to when the best biting occurs.
Good luck to you on the hunt!
