Kona Annual Rainfall Total: Kailua-Kona receives around 18″ of rainfall per year. Generally, most precipitation events are soaked up by the ground. During tropical storms or severe weather, more rain may fall than the ground can handle and therefore you can receive flooding. The excess rain will follow well-defined water run-off channels.
