About a year and a half ago, in Monterey, there had been a huge jellyfish swarm that had been lingering around the harbor for awhile. I had just gotten a new tray for my little Gopro hero 4 black and wanted to dive a sunken barge that's located off of the Breakwater (San Carlos Beach). I had a friend who had never dove the barge so me and my buddy Leo throw on some tanks and head down to the water.

So Leo and I are swimming out to number 11 to drop down and we see a couple jellyfish here and there. They do sting but the water there's so cold that you need a full body wetsuit plus hood just to get below the surface, so the only things exposed are your cheeks really. With all those jellyfish in the water we still thought we could make the dive since it was along open ocean and sandy flats and there couldn't possibly be more than what we were seeing.

Boy were we wrong. The further out we swam the denser they got, one was even 7 feet long. Wasn't long before we couldn't swim under or around them anymore. We took a compass heading back to the breakwall. Surprisingly neither of us got stung and we decided to continue to dive in the shallows with less jellyfish about after that.
