Weather by month
Kailua-Kona
Hawaii
The dry side of the Big Island, where the mountains wring the rain out of the trade winds long before they reach the coast.
The best time to come
February through April is the pick — humpbacks still working the coast, the ocean glassy in the mornings, and the summer heat still a few months off. Honestly, though, Kona has no bad month; it only has busier ones.
