HONOLULU (HawaiiNewsNow) - A cold front approaching from the northwest will erode the trade wind-producing high pressure ridge north of the islands, resulting in lighter southeast winds for Friday. The winds will become light enough to allow for afternoon clouds and isolated showers for interior sections. Showers could become heavier Sunday night and Monday as an upper trough digs down over the islands, with a slight chance of thunderstorms. The trough should depart to the east Tuesday and allow more typical trade wind weather to return.
At the beach, north shores will see small but steady surf through the weekend. A slightly larger northwest swell is possible Sunday, peaking Sunday night and Monday. There’s also some surf expected for south shores due to storms near New Zealand. Unfortunately, the fetch isn’t aimed directly at Hawaii, but we’re still expecting some higher waves. East shores will have minimal surf due to the absence of trade winds.
