Newbie question

Now that its getting cooler in the morning should I start fishing later after the sun comes up? Say I try to fish 5 --5:30 am on, now its cooler and darker should I start at 6:30 7:00am ? Any advice appreciated!

Fish as much as you can. The water temps are in the 70's at most of the places I've been recently. That's prime

We haven't reached that point yet Around October, yes

THANKS GUYS!
