Kailua-Kona Weather in September

Kailua-Kona on the Big Island's dry leeward coast is protected from trade winds by Mauna Kea and Mauna Loa. The result is one of Hawaii's sunniest, driest climates — perfect for the Ironman triathlon and world-class coffee cultivation. Evening downslope winds from the mountains provide natural air conditioning.

Excellent shoulder season — warm with fewer tourists in many destinations.
