Trade winds will taper off through much of this week as remnants of Tropical Cyclone Genevieve linger between the high and Hawaii. Clouds and showers will favor windward and mauka areas, with some enhancement possible for the western half Tuesday through Thursday due to an upper trough setting up to the west.

Generally VFR with weaker trade winds. Occasional MVFR ceilings and visibilities within more organized showers focused over windward and upslope mauka exposures. No AIRMETs currently in effect and none expected this period.

A ridge of high pressure north of the state will continue to weaken over the next several days as a front passes far north of the state. Trade wind speeds will weaken in response, lasting through Thursday. Trade winds should restrengthen by the end of the week as high pressure builds far north of the state. The Small Craft Advisory was cancelled this morning.
Surf along south facing shores will stay below seasonal averages with mainly background energy throughout most of this week. The next small, long period south swell will arrive by Saturday with a slight bump in south shore surf heights through Sunday. A series of south swells are expected the following week (week of Aug 9th), which should produce surf heights at or above seasonal averages.
East facing shores will remain rough and choppy with steady decreasing trends as the trade winds ease through much of the week. Small, medium period easterly swell generated from former Tropical Cyclone Genevieve will linger over the next few days.
Surf along north facing and west shores will remain flat to tiny through the forecast period except for areas exposed to the easterly trade wrap.
None.
