HONOLULU (HawaiiNewsNow) - Dangerously high waves are forecast to build through the weekend for south-facing shores, with surf peaking Sunday near 24 feet.

The National Weather Service in Honolulu has issued a high surf warning for all south shores through 6 p.m. Monday.

The south swell may be one of the largest in recent years, with waves peaking at 18 to 24 feet.

The swell is lower slowly, with waves at 15 to 20 feet Monday.

Impacts will be high, with ocean water occasionally sweeping over usually-dry beach areas, strong breaking waves, and strong longshore and rip currents.

Large waves may impact south-facing harbor channels, making it challenging to control boats.

Large breaking surf and strong currents will make it very hazardous to enter the water. Beachgoers -- especially visitors who are unfamiliar with local ocean conditions -- should heed all advice from lifeguards and know their limits.

On Maui, official closed South Kihei Road from Uwapo Road to Leilani Road due to high surf Saturday evening.

The state Department of Land and Natural Resources said it will close several state parks on Saturday, including the Hapuna State Recreation Area, Kua Bay and Kekaha Kai on Hawaii Island. It is considering closing Makena State Park on Maui on Saturday. On Oahu, DLNR said it is closely monitoring the Kaiwi State Scenic Shoreline near the Makapuu Lighthouse and the Keawaula section of Ka’ena State Park.

Hawaii County officials have closed several beach parks along the south-facing coasts of Hawaii Island, including parks in Puna, Ka’u and Kona, due to high waves that were enhanced by swells generated by former tropical cyclone Darby. These parks include:

  • Isaac Hale
  • Punalu’u (Camping canceled for the weekend)
  • Whittington/Honuapo (Camping canceled for the weekend)
  • Milol’ii
  • Ho’okena (Camping canceled for the weekend)
  • Manini Point / Napo’opo’o
  • Honaunau Boat Ramp
  • Kahalu’u
  • Magic Sands / La’aloa
  • Pahoehoe
  • Wai’aha Beach Park (Honls)
  • Hale Halawai
  • Old Airport
