We don't experience the great temperature changes associated with summer and winter like many places do. However, the seasons do bring other changes, especially in the waters surrounding us. Summer on the north shore means snorkeling in bays that are as calm as swimming pools on good days. During the winter those same bays are extremely dangerous to set foot in due to swells. World-championship surfers replace vacationing (and local!) snorkelers. Winter also brings the return of the majestic humpback whale to Hawaiian waters!
