A new high pressure area to the north of the state will bring the return of moderate northeasterly trade winds. An upper level low will linger around the western end of the state and will enhance incoming showers, especially for Kauai’s windward side. An old frontal boundary will bring more widespread showers around the middle of the week, with showery and breezy trade winds heading into the upcoming weekend.
At the beach, surf will remain well below advisory levels. A series of moderate short-period swells will boost north shore surf Tuesday, followed by larger long-period swells Thursday and again Saturday. East shores will be small to start the week, but rough and choppy waves will rise later in the week as trade winds increase. South shore surf will remain small all week.
Higher than normal ocean water levels and high astronomical tides will also bring some nuisance coastal flooding during the early-morning hours during the next few days. Predicted high tides of about 2.5 feet have actually come in about half-a-foot higher. Be prepared for minor coastal inundation of roadways, normally-dry beaches and boat ramps.
