Area Forecast Discussion
National Weather Service Honolulu HI
941 AM HST Mon Jul 1 2024

.SYNOPSIS...
High pressure will build north of the Hawaiian Islands today and
continue through the week resulting in breezy trade winds. Fairly
stable conditions will keep brief passing showers over windward
and mauka areas, mainly in the overnight to early morning hours.

&&

.DISCUSSION...
Satellite and radar imagery show clouds and passing showers over
windward and mauka areas this morning under moderate to breezy
trade winds. Limited available moisture should keep conditions
fairly dry today as high pressure builds north of the islands.

Guidance continues to show high pressure lingering north of the
islands through the week. Moderate to breezy trade winds will
persist through the first half of the week then strengthen to
breezy to locally windy by mid to late week. Expect a fairly
typical summertime trade wind weather pattern this week as high
pressure across the region stabilizes the atmosphere. Clouds and
passing shower will primarily affect windward and mauka areas,
with a slight increase in activity during the overnight and early
morning hours. With the exception of the Kona slopes of the Big
Island see some isolated afternoon/evening showers due to local
sea breezes, leeward areas should remain mostly dry.

&&

.AVIATION...
Moderate to locally breezy trades will deliver limited clouds and
showers windward and mauka through period. Brief MVFR possible
windward and mauka, but VFR expected to prevail.

No AIRMETs in effect.

&&

.MARINE...
High pressure north of the state will bring fresh to strong trade
winds through most of the week. A Small Craft Advisory is posted
for the waters and channels around the Maui and The Big Island.
Trades may weaken slightly on Wednesday, before a slight uptick on
Thursday and Friday.

No significant south swells are expected through this upcoming
week. However, a series of small south-southwest and southeast
swells will keep south facing shores from going flat.

Typical mostly flat summertime conditions will continue along
north facing shores through most of the week. East shore surf
will gradually trend up closer to seasonal levels late today
through the middle of this week as the trades strengthen over and
upstream of the islands. A fetch of strong northeast winds well
off the California coast should bring a small northeast (050 to
060 degree) swell by this weekend and into early next week. Some
of this swell should wrap into select north facing exposures as
well.

Water levels running roughly 0.5 ft higher than normal around the
Big Island combined with the new moon tides could cause minor
flooding issues between July 2nd and July 6th with peak water
levels expected on July 4th. Our last full moon, we did receive
reports of some areas of the coastline becoming inundated with the
high tide such as Coconut Island and Puhi Bay. A Coastal Flood
Statement will likely be needed for the Big Island near the 4th of
July. For the other islands, water levels are running just a
touch above normal and will likely not reach our criteria of 1
foot above the Mean Higher High Water (MHHW).

Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big
