"Luckily there's no major water rescues today, which helps out, but we have a lot of swimmers because the oceans are nice and calm. That tends to increase the sting ratio," said the Beach Patrol's Dave Foley.

WFTV, Orlando, reported that the lifeguards went through several bottles of vinegar, which helps ease the sting.

Jellyfish stings can be quite painful, Suzanne Schloot will vouch for that.

"It felt like a fork electrocuting my leg. I jumped on the surfboard and pushed my sister off. I started crying and yelling for my brother to come pull me back in," said Schloot, who was stung by a jellyfish on Saturday.
