You can often spot whales breaching offshore from the resort's beach and oceanfront rooms—especially from the Main Tower Oceanfront Deluxe and Beachfront Deluxe Suite categories.
Does it rain a lot at Mauna Kea Beach Hotel?

What are the ocean conditions like at Kauna'oa Bay?
Kauna'oa Bay, the resort's crescent-shaped beach, is generally calm and protected year-round. December through February can occasionally bring winter swells that create impressive waves offshore, but the bay itself typically stays swimmable. April through November offers the calmest conditions for snorkeling, swimming, and water activities. The bay is known for excellent snorkeling with sea turtles and tropical fish.
