Not like the small and non-stinging types, these will sting. Please take care swimming over the next few weeks. Suntan lotion is said to reduce the chance of a sting on arms,face, etc. Vasaline helps as well. Clearly wetsuits help so it might be advisable to wear yours if you had been sans-suit.
Cure:? I have used Ammonia to good success on some bad stings on Sunday. I will be carrying Ammonia in my tool bag in case you happen to be swimming when I am.
I don't think it should stop plans for you to swim, just watch out while swimming for brownish/redish jellyfish. Their tenticles can go for a few feet so eyes open :) Goggles are a must IMO. A sting in the eye can cause serious problems.
Rougher waters do reduce their presence in the water so hoping for some wind this week.
