Monster surf continues to hit most islands today before gradually weakening by midweek.

The National Weather Service extended a high surf warning for the north and west shores of Oahu, Niihau, Kauai, Molokai and for the north-facing shores of Maui until 6 p.m. today.

Surf along north and west shores of Niihau and Kauai, and the north shores of Oahu, Molokai and Maui will be 20 to 30 feet.

Along the west shores of Oahu and Molokai, surf is expected to be between 12 and 20 feet.

The west-facing shores of Hawaii island will experience surf between 5 to 8 feet today while the island’s north-facing shores should see surf between 10 to 15 feet, according to the high surf advisory posted for the island this morning.

Surging ocean water sweeping over beaches, coastal benches and roadways could create the potential for significant damage to coastal properties and infrastructure.

The large breaking surf and dangerous currents will make entering the water very dangerous and anyone entering the water is urged to heed all warnings and instructions by ocean safety officials.
