Kona Storm and South Swell Exposure (West Maui Roadsteads)

20° 52.0′ N · 156° 41.3′ W · approximate

West Maui's roadsteads are calm in the normal northeast trades but open to the south and west: a kona (southerly) storm or a big south swell turns Lahaina, Mala and Kaanapali into lee shores.

Practical

Coordinate is approx (Lahaina roadstead). The Coast Pilot calls the Lahaina anchorage exposed in kona weather and Maalaea Bay 'completely exposed to kona storms' with poor holding. Kona systems are most likely in winter (area overview); south swells mainly in summer. Have a plan to run to Kahului (inside the breakwaters) or a sheltered harbor on another island, and leave shallow anchorages on a tsunami warning.

Best for

Knowing when to leave the West Maui moorings

Season
