Sharks love overcast sky and less clear water like storm periods. They come in closer and are more game.

To fight the Lionfish plague in the Caribbean, they began feeding sharks the lionfish off the tips of their spears.The sharks would eat them, via head first and this seemed like a successful act of making lionfish a target for sharks.
Trouble was, that the sharks associated the lionfish with humans and within a year, sharks were aggressively targeting divers for food, then biting the divers themselves.

When I was hanging out in Stewart Island, NZ. The local knowledge of diving with Great Whites in the strait, was that they were shy and harmless, in subordination to the local Orca. Divers had no trouble.
Then some group from the Bluff began 'research'. That research was for Cage Diving Tourism. They were chuming and feeding the Great Whites, to bring them to the cages. In 8 years, locals on both sides of the strait were angry as hell, as the Great Whites associated food & humans together as they had become aggressive, banging boats and tinnies, like seagulls for a chip. It was no longer deemed safe to open dive, as the Great Whites would also bump divers from out of nowhere.

Duh dum.
Duh ...dum.
Duh dum... duh dum... duh duh duh dum dum dum.

During drought spells bullsharks come 20km up the river, one stolen bream off the hook right next to my kayak about 7 years ago.

What I find amazing is that from all the time I've spent in the ocean, I've never seen a shark from a species considered dangerous.

I've swum with bull sharks.

I didn't know they were sharks at first though.

It was in Port Hedland, WA.

When I finally figured out what the things in the water were (bumping in to me), I got out REAL fast!

I was out before the heavy rain hit, so the water wasn't really murky.

Today it would have been like brown soup, I'd never go out in that.
