The tides vary 6+ hours daily,say high at 1:00am then low at about 7:30 am then high again at 2:00 pm etc.This time of year there are negative tides that allow for good beach running or poke pole fishing in the shell beach rock areas. Its not so much the tides but if the creek starts running again. As you saw the creek exits the levee and goes far south now. It used to go straight out until the storms in 95 or so?? Best bet usually is to watch others first, cross between sets of waves when the water is out so to say and dont stop or let some dumb ass stop in front of you either. If this happens it can get ugly fast as the water rushing under your rig will wash the sand out from under your tires quickly and you be sitting on your undercarrage and stuck.. Some dude did this to me when I was in D50 2wd truck, it buried me and within 30 seconds the waves were over the hood. Luckly a friend pulled me out before the truck got wasted.
