High Surf Advisory to be issued Tuesday for north-facing shores of Big Island
Surf will trend up Monday night along north- and west-facing shores as a small to moderate, medium-period northwest swell builds down the island chain, according to the National Weather Service.
As this swell peaks later Monday night, a more significant north-northwest swell is forecast to drive surf to advisory levels Tuesday as it peaks.
Surf is expected to build to 15 to 20 feet along the north-facing shores of the Big Island, from 6 a.m. Tuesday to 6 a.m. Thursday.
Impacts will be moderate. Strong breaking waves and strong currents will make swimming dangerous.
