Welcome to IDA Whip.
There are a few things to consider when trying to pinpoint a Prime-time for Channels.
This is the time of year when the Channels start to bite pretty aggressively. (you want to start when water temps hit 40 or greater, the warmer the water the more active.) I’m guessing that your water temps could be above 50F already.
Time of day for channels doesn’t seem to matter, though my experience is the the larger ones seem to prefer the early evening hours, (could be that I’m trying for bigger flats and only the large channels would be able to take a shot at my bait).
Talk to some other fishermen in the area and see if you can’t find out some info on whats working for them. Also we have a lot of info if you look at previous posts, As you read through you will see that there are patterns but spots can dictate what times and techniques to use.
Good Luck Mate.
