Invasion of Giant Jellyfish !

I can confirm,as reported,that there are lots of Giant jellyfish off the Coast of Cornwall.I have seen them today when out on jetski with friends.
Also i normally dont go that way in June as the waters off the North Cornwall coast dont usually warm up till Aug/Sept.So we tend to go further South.
Very odd swimming in the sea yesterday,like when you are in a swimming pool and swim past the warm water jets ! Really warm currents then cold bits.Not had that before.
Jellyfish probably about four or five foot across.Kicked a little one yesterday whilst surfing but lucky this lot dont sting bad.
