HONOLULU, Hawaii (HawaiiNewsNow) -Moderate trade winds will gradually strengthen through Sunday as high pressure builds far north of the state. An upper level trough passing overhead will produce some high clouds and will enhance rainfall in the trade wind flow this weekend, especially over the eastern half of the island chain late tonight and Sunday. A drier and increasingly stable air mass will set up over the state on Monday, leading to a decrease in shower activity. Trade winds will decrease on Wednesday and remain at moderate strength into next weekend, leading to typical trade wind weather.
East facing shores will experience greater than 8 foot breakers that may prompt an early week High Surf Advisory (HSA) for many eastern exposures. Due to the northerly component of this swell, surf along north facing shores will also pick up to more moderate 7 to 11 foot heights. North surf is expected to remain under the 15 foot HSA criteria. A small, long period south swell will maintain near seasonable surf along the southern shores.
