Im pretty sure sharks are found more often on nights around 7pm, thats where I normally find them and on the island later on in midday, I found 3 at around 8pm on the same side of the island right next to eachother, they're everywhere there
Thank you! I tried all your methods. I do have the island, but I found them more when it was raining and around the 7-9pm time slot. Thank you for all the replies!
Didn't realize there were specific times for it besides sunset on. I go to the Island after the shops or retail close so that's pretty late and I still get plenty in between my bug catching.
