Synopsis
Light trade winds can be expected through tonight with just a few
passing showers favoring windward and mauka areas. Winds will
become lighter over the next couple of days as a front lingers
northwest of the area. High pressure will build back in beginning
Wednesday with a gradual uptick in trade winds expected through
the remainder of the week. Clouds and passing showers will favor
windward and mauka areas with just a few light showers expected
over select leeward locations.

Discussion
Updated discussion to include the high surf advisory for south
facing shores of all islands.

High pressure is centered far northeast of the area while a
stalled frontal boundary lies a couple of hundred miles northwest
of kauai. This places the islands in a light easterly trade wind
environment. Moisture embedded in the trades is providing for some
light passing showers over windward and mauka areas while most
leeward locations are dry. Expect this trend to continue through
the evening and on through the overnight hours.

The high will shift slightly eastward Monday and Tuesday. This
will cause the winds to become a bit lighter and favor and east to
slightly south of east direction. Daytime sea breezes and
nighttime land breezes will become more prevalent under these
conditions. Passing light showers will continue to favor windward
and mauka areas with some interior showers a possibility during
the afternoon hours due to day time heating and sea breeze
convergence.

By Wednesday, the high to the northeast will build back in a bit
toward the area as the old frontal boundary northwest of kauai
weakens and drifts further away from the area. This will allow for
a gradual uptick in trade winds beginning Wednesday with speeds
reaching moderate to locally breezy levels as we head into next
weekend. Clouds and passing showers will favor windward and mauka
areas with leeward areas remaining mostly dry with just a few
light showers expected.

Aviation
High pressure to the northeast will drive moderate trade winds
through tonight before winds weaken and shift east southeast on
Monday. Clouds and showers moving in with the trades will focus
over windward slopes.VFR conditions will prevail, but brief
mountain obscurations may occur over the windward slopes. No
airmets are in effect at this time.

Marine
Winds are on the decline as the high far to the northeast slowly
weakens. Expect lighter winds into Wednesday. A ridge building
north of the islands during the second half of the week should
allow winds to rebound into the breezy to strong range.

The incoming south swell has been rising slightly through the day,
with the resultant surf just below advisory levels. This swell is
expected to begin lowering in the next 12 hours or so. A new
long-period, although slightly smaller, south swell is expected
to arrive late Tuesday or early Wednesday and hold into the latter
part of the work week.

A small northwest swell associated with a gale that crossed the
date line a few days ago is expected to begin to slowly ease
Monday through Tuesday. Another north-northwest swell is possible
Thursday. Surf along east facing shores will remain somewhat
elevated through this evening due to the recent breezy to strong
trades upwind from the islands. Expect a downward trend by
memorial day as the trades marginally weaken.

Hfo watches warnings advisories
High surf advisory until 6 pm hst Monday for south facing shores
of all islands.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
