HONOLULU (HawaiiNewsNow) - The National Weather Service issued a high surf warning which is in effect from 6 p.m. Monday through 6 a.m. Wednesday.
A north-northwest swell will produce warning level high surf for north and west facing shores along Niihau, Kauai and Oahu, and the north facing shores of Molokai, Maui, and the Big Island of Hawaii.
A high surf advisory is also in effect for east facing shores of Oahu.
The weather service said waves along north shores could reach 25 to 35 foot face heights, with some sets to 40 feet along the outer reefs. Similar heights are possible for Kauai and Niihau's west shores.
Waves along the west shores of Oahu and the north shores of the Big Island could see 15 to 25 foot waves, with higher sets.
The waves could result in rip currents which can easily overpower even strong swimmers, and cause coastal erosion along shores exposed to the northwest swell.
