An east to west surface ridge over the coastal waters will produce light and variable winds through tonight. A high west of the dateline is moving east and pushing a front southeastward toward Hawaii. The front will be dissipating as it moves over the coastal waters tomorrow morning. Northeast trade winds will spread across the dissipating front over the coastal waters through the day tomorrow. Winds will reach Small Craft Advisory speeds over the windier areas by Monday morning. The trade winds will strengthen further through next week as a strong high builds northeast of the area. SCA winds will likely affect most areas of the coastal waters by the second half of next week and winds may reach near-gale force in the windiest areas.

The current northwest swell will produce surf a few feet below the high surf advisory (HSA) level as it peaks this morning. A new northwest swell arriving tonight will again produce surf near the advisory threshold when it peaks tomorrow night. The swell will subside through Wednesday. Surf for north and west facing shores then looks pretty quiet through the end of next week.

Surf along east facing shores will build next week as trade winds strengthen. Only small surf is expected for south facing shores.

Weather Outlook for Saturday, 6th April 2019


Mainly fair weather will prevail through tonight with daytime sea breezes and nighttime land breezes. A weak front may reach Kauai on Sunday then stall early next week. Some showers can be expected with the front but they will generally be on the light side. High pressure will build north of the area next week with breezy trade winds returning. Trade wind weather may become wetter later part of next week as an upper trough digs down east of the state.

Detailed Discussion

A ridge extending east to west over the islands will continue to keep the synoptic winds light today. Nighttime land breezes will slowly early this morning will give way to daytime seas breezes by afternoon. There are some low clouds in the island vicinity early this morning, though much of these are over coastal waters. The exception will be Kauai and windward east Maui where some clouds and even showers are affecting those areas. Early morning Lihue and Hilo soundings continue to depict a stable and rather dry airmass. Do expect clouds to develop over the islands in the afternoon and evening once again. Not much, if any, precipitation is expected.

There is a front northwest of the islands and may advance to near Kauai early Sunday. The front will be weak and rather shallow by the time it gets close to the islands. Thus it is not expected to be much of a weather maker. The aforementioned ridge in the area will be shifting east tonight, with winds becoming more northerly across much of the island chain ahead of the pending weak front. Still mainly fair weather is expected for the area tonight.

This front is expected to stall later on Sunday and dissipate near Kauai Monday. Moisture from this front will affect mainly Kauai, though forecast solutions do hint an increase in overall moisture elsewhere in the island vicinity. As a surface high pressure is forecast pass north of the islands behind the front, expect easterly trade winds to return to the area late Sunday into Monday. Clouds and showers will primarily be focused over windward and mauka areas under the increasing trade winds.

Forecast models indicated a rather strong surface high pressure will persist far northeast of the islands through much of next week. Hence, moderate to breezy trade winds are expected for the islands through the period. An upper level trough is forecast to pass over the islands early next week, then deepen east of the area by the middle of next week. Latest ECMWF has come around to be more inline with GFS, forecasting the trough closer to the islands. Looks like wet trade wind weather may be in store for the state later half of next week.
