Strong trade winds will bring increased short-period surf to east facing shores, which is likely to be the largest surf for any island shores over the next week. Near shore windward buoys indicate combined seas near 8 feet, and although surf will remain elevated along windward shorelines today, it is expected to remain below advisory-level heights. Small, long-period pulses of south swell will occasionally supply small to moderate surf to south facing shores, with Friday’s pulse trending down through Saturday. There is also a potential for a tiny northwest swell around Thursday, but surf is expected to remain below advisory levels along all shores through the period.

High pressure passing far north of the islands will support strong to near gale force winds through tonight before easing slightly Sunday and Monday as the high moves east at 25 kt. An overnight ASCAT pass sampled Kauai and Oahu waters, and indicated numerous areas of 25 kt winds, while gusts near 30 kt have been reported at some of the windier land-based stations overnight. Thus, a Small Craft Advisory (SCA) remains in effect for all Hawaiian waters through tonight. The easing winds will likely allow the SCA to be trimmed back to fewer areas Sunday into Monday. As a new high builds far northwest of the islands early next week, moderate to fresh trade winds are expected, but will be backed slightly to the northeast (especially near Kauai) as the high will remain centered northwest of the area. As the high tracks east later next week, latest guidance continues to indicate that a weakening east-west oriented frontal boundary will move south toward the area, potentially bringing increased showers to the northern portion of the Hawaiian Offshore waters by mid-week.

Weather Outlook for Saturday

Breezy and gusty trade winds are expected to continue through the weekend as high pressure passes north of the state. Clouds and showers will favor windward and mauka areas each day into next week, with occasional showers spilling over to leeward areas. Trade winds are forecast to trend down slightly early next week as high pressure weakens to the north and the remnants of an old frontal boundary sink southward toward the islands by the end of the week.

The latest surface analysis showed 1028 mb high pressure centered well north of the state with a ridge axis extending southwest toward the Date Line. This feature passing to the north supports the gusty trade winds continuing across the islands today. Wind gusts reaching as high as 30 to 40 mph, similar to yesterday afternoon, will be possible once again today. In addition to the winds, showery conditions, mainly over windward and mauka areas, will continue through the early morning hours due to a band of scattered to broken low clouds that filled in across the island chain overnight.

The short-term guidance remains in good agreement and depicts stable and mostly dry conditions with breezy trade winds prevailing through the weekend as high pressure to the north shifts northeast of the state. Although clouds and showers will continue to favor windward and mauka areas each day, some will manage to spill over to leeward areas occasionally due to the stronger trades in place. Model precipitable water values are projected to remain around normal for this time of year (around 1.25″) each day through the weekend.

Guidance remains in decent agreement into the upcoming week and indicates a weakness within the subtropical ridge developing north of the state Monday through Wednesday as a cold front passes north of the region. Trade winds will respond and slightly weaken over the local area through this time. A band of higher precipitable water located along the tail-end of this dissipating frontal boundary is forecast to sink southward toward and possibly over the smaller islands through the second half of the week, which may correspond to increasing shower coverage. High pressure will build north of the state Thursday through Friday, likely strengthening the trades locally once again.
