These are my best tips for deep south bowhunting. To qualify, I live 50 miles north of the Gulf of Mexico and have 90k acres of WMA literally bordering my backyard. Double that acreage within an hour drive. Have hunted Alabama, Florida, Mississippi, Louisiana, and Georgia. Since I got out of college I average 5-10 deer a year on public land. I don't consider myself an expert, but I do ok and know a lot of guys who are really and truly experts.
First, piss on any weather that doesn't necessitate at least a pullover for the first couple of hours. I lost gallons of blood and sweat on 80 degree or hotter sits before I realized that I'm better off fishing. Cold fronts are the name of the game. They're more pleasant, get the deer frisky, and offer you at least a chance at keeping your funk level low.
Second, at least where I'm at, is knowing that while it may look like there's a lot of browse, most of it is woody and low value. Deer right now are about as hungry as they're gonna get. If you have a corn feeder, food plot, or a hot oak...that's where you want to be sitting. I live and die by
@WHW's advice surrounding feed trees during early season, because once they start dropping they're about the only wild food source, and they're naturally preferred anyway. Deer live to eat and screw, and right now it's not screwing season. They're just going from hidey spots to acorn-snarfing spots. And usually, in my experience, the hiding spot is within 100 yards of the snarfing spot. Hang directly over the food and be as quiet as possible while doing it.
If you disregard point number one, I'd say the first and last hour are your best bets. No sense in an all day sit. On a cold day, I've had luck in the middle of the day. You stand a decent chance at catching a group of bachelors, so keep that in mind when a fork horn comes bebopping down the trail.
