low tide high tide date
location is H H I
what more need to know?

I ask again?
If you know where you are and you are on Hilton Head Island.
If you know where you are and you know when high tide and when low tide is.
If you know where you are and you know the date.
If you know where you are and know what the colors of the warning flags mean.
Red flags mean there is a high hazard of dangerous currents and / or surf OR Sharks OR lightning seen in the area.
And that’s a pretty good lists of hazards to be aware of.
Yellow flags mean there is a medium hazard of moderate current and / or surf and it says nothing about sharks (though a good friend of mine says if you put your finger in the water and then taste it; if it tastes salty there are sharks in the water).
Purple flags mean there are Marine Pests Present. Marine Pests mean things that STING like jellyfish or stingrays while I include anyone on the beach that has to, and I mean HAS TO play some game that involves throwing something. I mean really, you put all this effort into getting to the beach and relaxing in the sun by the water and yet there are those who after one or two minutes of relaxing, jump and say, “who wants to throw something.” That includes baseballs, tennis balls, footballs, frisbees and just anything that can be thrown if any of those items were not brought along. It also involves kicking soccer balls, bumping volleyballs and golfing. It makes no matter if its low tide and there are acres of beach, they set up right next to you or high tide where there is no space for such games but these pest persist in throwing footballs or baseballs or kicking soccer balls through a crowded mass of people like its their lives depended on it. And as a good part of these pests are imbibing beverages of an adult nature, their accuracy steadily diminishes as the day goes on. These pests possibly the biggest hazard on the beach.
BUT I DIGRESS!
If you know where you are and you know the when high tide is.
If you know where you are and you know the when low tide is.
I ask you.
What more do you need to know?
