Scientists said the increase in encounters is likely because there are more ocean users, more cameras and more public awareness. Plus, the peak of Hawaii's whale season is late January to early February.

"There's not a better place on the planet to be in the winter months," Yee said.

Federal law prohibits all ocean users from approaching within 100 yards of a humpback. If the whale approaches you, the National Oceanic and Atmospheric Administration asks that you remain still and let it pass. If you're in a motorized vessel, put your engine in neutral.
