Hawaii marine forecasts: common questions

Is there a small craft advisory off Hawaii right now?

No advisory or warning is in force in any of the 15 Hawaii marine zones at the moment. Advisories are issued per zone by the National Weather Service and appear at the top of a zone's page as soon as one is posted.

How windy is it on the Hawaii coast right now?

Buoys off Hawaii are reporting 3 to 15 knots, the strongest at Alenuihaha Channel. A knot is 1.15 mph, so 20 knots is about 23 mph. Wind measured offshore is usually stronger than the same wind felt in a harbor.

How rough are the seas off Hawaii today?

The highest seas measured right now are 7 ft off Alenuihaha Channel, out of the 14 of 15 Hawaii zones with a wave-capable buoy nearby. Seas are significant wave height, the average of the highest third of the waves, so individual waves run noticeably higher than the figure.

Who issues the marine forecast for Hawaii?

The National Weather Service, from its Honolulu, HI office. Each of the 15 zones on this page gets its own bulletin in a legacy teletype format, reproduced here in full underneath the charts and the live buoy readings.
