A High Surf Advisory is now in effect until 2 p.m. Tuesday for the east-facing shores of most islands as strong trade winds will produce rough and choppy surf.
The National Weather Service in Honolulu said surf will rise to 6 to 10 feet by Saturday, and increase to 8 to 12 feet Sunday through Tuesday.
Surf is expected to remain high until the latter part of next week, when the trade winds are forecast to weaken.
Beachgoers can expect strong breaking waves and shorebreaks, along with strong longshore and rip currents that will make swimming difficult and dangerous. Swimmers and surfers should heed all advice from ocean safety officials and exercise caution.
