HONOLULU (HawaiiNewsNow) -
The high pressure fan north of the Hawaiian Islands will remain in a weakened state through Friday as several cold frontal systems pass to the north of the region. Large scale atmospheric stability will keep Hawaii in a mostly dry weather pattern with limited shower potential into the weekend. Light winds will allow local scale land and sea breezes to develop over each island through the week.
Low pressure systems moving rapidly eastward across the north Pacific will send small to moderate northwest swells toward the islands through Friday. In addition, a new north swell will slowly fill in Tuesday, followed by a longer period moderate sized north-northeast swell starting Tuesday night. This swell will build, and may cause seas to reach the SCA criteria across some windward waters on Wednesday. In addition, since the swell has an easterly component, surf heights may reach the High Surf Advisory (HSA) threshold along east facing shores starting Wednesday.
A new large northwest swell is expected to start spreading across the waters adjacent to the western end of the island chain late Friday night. This swell will likely increase seas above the SCA threshold across exposed waters from Saturday through Sunday. Surf is also expected to be near the High Surf Warning criteria along most north and west facing shores of the smaller islands next weekend.
