UPDATE: High surf advisory extended through Tuesday for eastern shorelines

Update at 4:19 a.m. Feb. 16, 2026: Strong trade winds will maintain relatively short period high surf along east-facing shores of the Big Island lasting into Wednesday.

As a result, the National Weather Service forecast office in Honolulu has extended the high surf advisory until 6 p.m. Tuesday (Feb. 17) for the eastern shores of the North Kohala, Hāmākua, North and South Hilo, Puna and Kaʻū districts.

Large breaking waves of 7 to 12 feet are still expected.

Story originally posted at 5:38 p.m. Saturday, Feb. 14, 2026: Already strong trade winds will strengthen another notch Sunday (Feb. 15) and produce high surf along east-facing shores during the next several days throughout the state.

As a result, National Weather Service forecasters in Honolulu issued a high surf advisory in effect until 6 a.m. Tuesday (Feb. 17) for eastern shorelines of North Kohala, Hāmākua, North and South Hilo, Puna and Kaʻū districts on the Big Island.

A high surf advisory means surf will be higher than normal. Strong breaking waves and strong currents also will make swimming and other ocean activities dangerous.

Large breaking waves of 7 to 10 feet are forecast, rising to surf of 8 to 12 feet by late Sunday into Sunday night for eastern shores.

“Beach-goers, swimmers and surfers should heed all advice given by ocean safety officials and exercise caution when entering the water,” said Hawai‘i County Civil Defense in a message Saturday afternoon.

National Weather Service forecasters reminded the public: when in doubt, don’t go out.

Winds are expected to stay strong through the middle of next week, so the advisory could be extended.
