A ridge between New Zealand and the Samoa Islands continues to
hold fair weather for the territory. Expect east winds to
diminish further tonight to 10 to 20 mph, ending the breezy and
windy weather experienced throughout last week. This slightly
weaker ridge will maintain east winds of 10 to 15 mph for the rest
of the week and into the new week. Rainfall is also expected to
be below average through the forecast period as showers are
focused farther north of the territory.

Additionally, expect warmer highs and lows for the next few days
due to weaker trade winds.

Latest wave heights observed at the Aunu`u PacIOOS buoy range
between 10 and 11 feet, while the King Poloa buoy shows wave
heights around 7 feet with peak periods of up to 14 seconds.
These observations suggest elevated seas will remain, and a south
swell continues to impact coastal waters. Although surf is
currently on the lower end of the High Surf Warning, we will
extend the warning through tonight, or until wave heights subside
below warning criteria. Thereafter, a High Surf Advisory may
replace the warning and remain in effect until seas subside below
advisory criteria by Thursday. Better ocean conditions are
expected for the weekend, though winds around 15 knots could
maintain slightly choppy conditions through the new week.
