About Old Kona Airport
- Old Kona Airport faces west-northwest (290°): swell from that side arrives head-on.
- Swim or kayak in from shore, or go by boat from Honokohau Small Boat Harbor.

What spoils the visibility here
- North and northwest swells, mostly October to April, hit it head-on and stir up the bottom.
- It is sheltered from the usual trade winds; Kona (southerly) winds and swells are its weak spot.
- Heavy rain sends brown runoff into the water for a few days; Hawaii DOH posts Brown Water Advisories when it does.
