Yesterday, the beach was emptier than I’ve ever seen it. Figuring it was due to the high wind — the retreating edges of Tropical Storm Fred, by then pushing north to the panhandle — I took off walking as I usually do, tennis shoes slung over my shoulder, sinking my toes in the sand, warm water flowing up to my ankles as I skirted the waves.
It was a perfect beach walking day — except it was anything but.
I had heard about Red Tide, an algae bloom that kills fish and other wildlife, but mistakenly thought that if you couldn’t see it, it wasn’t there.
But then the cough I had noticed earlier became more insistent and my eyes watered so much I could scarcely keep them open. Could Red Tide hurt humans, too?
The lifeguard station was farther up the beach, and by the time I reached it there was another coughing, sneezing, watery-eyed person asking the same question.
“It’s really bad today,” said the guard, who was wearing one of those bandana masks that’s not allowed on airplanes but which seemed to be helping him cope with Karenia brevis, the organism that was causing the symptoms.
When I looked closer, I noticed the little red flag flying from the lifeguard stand. Red Tide: I have a healthy respect for it now.
