Weather in Waikoloa (Kona resort coast): temperature, rainfall and cloud cover

Waikoloa is a small community on the north Kona coast. It also is close to some of the biggest and most popular resorts on the Big Island: Waikoloa Beach Resort, Hilton Waikoloa village, and the Waikoloa Beach Marriott Resort & Spa, the Fairmont Orchid, and many luxurious vacation rental condo’s at Mauna Lani, to name a few.
