Area Forecast Discussion
National Weather Service Pago Pago  AS
115 PM SST Sun Jul 13 2025

Overall, no severe weather is anticipated for the American Samoa
islands throughout the next 7 days. However, choppy seas and
elevated surf are forecast through at least the middle of the
week.

.Short term...

A strong high pressure system centered currently to the southeast
is producing trade winds up to around 20 mph over the territory.
Otherwise, a mix of sun and clouds remained this morning and early
this afternoon. These conditions are expected to remain throughout
the day Monday. If showers occur, it would be in the passing form. By
Monday night, the high is forecast to move further away from the
region. This is anticipated to decrease the easterlies, but only
slightly to around 15 mph through Tuesday. By Tuesday night and
Wednesday, another high pressure system from the southwest is to
increase trades once again to reach around 20 mph. Scattered
showers remain throughout this period, mainly in the passing form,
and flash flooding is not likely.

.Long term...

The aforementioned high pressure system is expected to continue
influencing the weather over American Samoa through late in the
week, but wind speeds slowly decrease late in the week. A weak
trough is to develop by next weekend, which would increase showers
to numerous showers (70% chance) but flash flooding is not
likely.

.Marine...

The moderate to fresh easterly trades continue to provide rough
and choppy seas along the American Samoa coastal waters region.
Winds only decrease slightly overnight to around 15 to 20 knots
(compared to around 20 knots as of this morning) and eventually
down to around 15 knots on Monday night and Tuesday. However, the
easterlies are still anticipated to elevated seas within the Small
Craft Advisory criteria (8 feet or above). Another high pressure
from the southwest influences the region on Tuesday night through
the rest of the week to produce a fresh east/southeasterly breeze
to keep seas choppy. A southerly swell is to move through the
American Samoa coastal waters to elevate surf along the southern
shores in the middle of the week.
