The National Weather Service has issued a high surf advisory for the south shores of all Hawaiian islands, effective until 6 p.m. today.
A swell from the east of New Zealand will keep surf above advisory level, at 6 to 8 feet, for south shores through this evening, forecasters said, then subside on Tuesday.
The public should expect strong, breaking waves and currents along south shores, making swimming difficult and dangerous. Beachgoers should heed all advice from ocean safety officials.
Today’s forecast, meanwhile, includes an increased possibility of rain this morning across Kauai, Oahu and Molokai, mainly windward and mauka. Scattered showers are also expected for most isles this afternoon.
Highs today are expected to range from 85 to 90 degrees Fahrenheit, while lows dip to 69 to 74.
Trades are expected to remain light to moderate today through Friday.
Forecasters also say the Kona coast may see extended evening showers from sunset until midnight due to on-shore winds converging with downslope mountain breezes.
Surf on north shores is expected to rise from 3 to 5 feet this morning to 4 to 6 feet Tuesday, while surf on west shores is expected to lower from 3 to 5 feet this morning to 2 to 4 feet Thursday.
Surf on south shores, where an advisory is in place for today, will lower from 6 to 8 fee today to 4 to 6 feet Tuesday.
Surf on east shores remains stable at 2 to 4 feet today and Tuesday.
Forecasters say a few more southern hemisphere swells will produce small surf along south shores through the second half of the week.
A new northwest swell will produce small surf along north and west shores through Tuesday, with another small northwest swell expected Wednesday. Surf along east shores may increase a bit over the second half of the week as winds strengthen off California.
