Marine Weather Message in Effect for the Coastal Waters

Marine section from the Area Forecast Discussion
issued at: Jun 15, 2019 8:05 PM HST

High pressure far northeast of the state will maintain fresh to locally strong trades through the middle of the coming week. Winds may veer east-southeasterly Monday into Tuesday as a weak trough develops far west of the state. A Small Craft Advisory (SCA) is in effect for the typically windy waters around the Big Island and Maui through early Monday morning. This will likely need to be extended at least into Wednesday.

Elevated surf is expected along south facing shores through early Sunday morning. Due to the swell still holding strong into this evening, the High Surf Advisory has been extended through tonight. For next week, we should see several reinforcing south- southwest swells for the first half of the week with surf heights around the summer average through the middle of the coming week.

A reinforcing northwest swell is filling in tonight and will continue to produce surf in the small to moderate range along north facing shores through Sunday. Additional pulses of tiny northwest swell are expected through next week. Surf along east facing shores will remain small through the weekend, then rise early next week.

The marine forecasts issued are based on marine observations and model data. Marine observations include buoy and ship reports. Ship reports are invaluable to the NWS, and are reported through the U.S. Voluntary Observing Ship Project. If you are a mariner, please consider joining the nearly 1,000 volunteer ships from around the world that observe the weather at their location.
