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

You are here: Home >> Kailua Kona >> Weather at the Waikoloa resorts

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.

The Waikoloa coast is so popular due to it’s exceptionally dry and sunny weather. It almost never rains, clouds are rare, and temperatures range from pleasant to superb. This makes sense when you know that the official climate zone designation for this part of the Big Island is ‘Desert’.

You can see this in more detail below, where we present you the yearly averages at Waikoloa for the temperature, the precipitation and the number of cloudy days.
