UPDATE: High surf advisory extended for east-facing shores of the Big Island

Update at 7:08 a.m. Nov. 14: The high surf advisory that was issued for east-facing shores of the Big Island has been extended until 6 a.m. Thursday. Surf of 7 to 10 feet, building to 8 to 12 feet tonight, is expected.

The National Weather Service says large and rough surf associated with strong onshore winds and large seas will lead to hazardous beach conditions through midweek for exposed north and east-facing shores.

Original story: The National Weather Service in Honolulu issued a high surf advisory for east-facing shores of Hawai‘i Island, in effect from 6 a.m. Tuesday till 6 p.m. Wednesday.

A large and rough surf is expected due to the combination of very strong to gale-force trade winds and a large northeast swell generated by a gale-force low far northeast of Hawai‘i. Surf will gradually lower during the second half of the week as the trades begin to ease and the northeast swell fades.

It’s anticipated the rough surf will be 7 to 10 feet on Tuesday, with a possible increase on Wednesday. Impacts will be moderate with strong breaking waves and strong currents making swimming dangerous.

Head all advice from ocean safety officials. When in doubt, don’t go out.
