May 2 visit
I got to lot 5 just after 12 and there were no spots to be had. Back to lot 4 and plenty of spots. The only folks I saw were nude. A lot of seaweed is washing up on the beach so I think the flies might be a nucience. They were also flying the purple flag but I'm not sure what for. Lot 3 is open now also. It was another beautiful hereby day at Apollo today.
Did a little looking around and came up with this info.
Don't know how accurate it is.

from tripsmarter
A GREEN flag means that the water is calm. The undertow is slight to non-existent and it is safe to swim using the proper amount of caution!
A YELLOW flag indicates the presence of light surf or currents and additional caution should be used while swimming in the Gulf.
A RED flag indicates the presence of strong surf and currents. Swimming in these conditions is not recommended as it presents a very high hazard to all swimmers.
A DOUBLE RED flag, however, means that the water is closed to the public! No one is allowed in the water when a double red flag is posted!
Finally, a PURPLE flag indicates the presence of marine pest in the water such as jellyfish, stingrays or dangerous fish.
