0405 UTC Wed Nov 26 2025

Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.

Based on 0000 UTC surface analysis and satellite imagery through
0200 UTC.

...SPECIAL FEATURES...
Gulf of Tehuantepec Gale Warning: A cold front will move across
the Gulf of America through late Thu. The pressure gradient
between strong high pressure building in the wake of the front
and the eastern north Pacific monsoon trough will support fresh
to strong gap winds and rough seas across the Gulf of Tehuantepec
tonight and Wed. These winds will increase to gale force by
early Thu. A plume of fresh to strong N to NE gap winds and seas
of 8 to 10 ft will reach into Pacific waters up to 500 nm
downstream of the Gulf of Tehuantepec by late Thu. Winds and seas
will diminish Fri and Sat as the high pressure north of the area
shifts eastward and the pressure gradient loosens.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough extends from 08.5N78W to 09N87W to 07N103W.
The ITCZ extends from 07N103W to beyond 09N140W. Scattered
moderate convection is observed from 05N to 09N between 104W and
120W, and from 04N to 16N between 125W and 133W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Moderate to fresh NW winds prevail over the Gulf of California,
reaching strong speeds over the central portions. Gentle to
moderate winds extend from the mouth of the Gulf to Cabo
Corrientes. Light to gentle winds are noted elsewhere. Seas are
in the 7-8 ft range west of the Baja California peninsula
extending southward to the Revillagigedo Islands and eastward to
the waters off Cabo Correintes. Seas of 3-6 ft prevail
elsewhere.

For the forecast, fresh to strong gap winds will develop in the
Gulf of Tehuantepec late tonight into early Wed, increasing to
gale- force Thu morning through Fri morning leading to rough
seas. Fresh to strong winds will then persist in the Gulf of
Tehuantepec into early Sat before diminishing. Farther north,
moderate to fresh winds will pulse in the Gulf of California into
mid- week, briefly strong at times, then diminishing Thu. Large
NW swell off Baja California and the Revillagigedo Islands will
subside this evening. A weak cold front or trough will move into
the waters off northern Baja California, supporting moderate to
fresh westerly gap winds across the northern Gulf of California
Sun night.

...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...

Moderate to locally fresh NE winds are over the Papagayo region,
with moderate winds extending downstream to near 95W. Light to
gentle winds are elsewhere north of the monsoon trough. Gentle to
locally moderate winds are found south of the monsoon trough.
Seas are in the 3-5 ft range.

For the forecast, moderate to fresh NE winds will pulse over and
downstream of the Papagayo region the remainder of the week and
into next weekend, locally strong at times. Moderate or lighter
winds are forecast elsewhere through the week and into next
weekend. No significant swells are forecast this week.

...REMAINDER OF THE AREA...

The pressure gradient between ridging north of 20N and lower
pressure in the vicinity of the ITCZ is supporting moderate to
fresh winds N of the ITCZ to near 20N and W of 110W. The trade
winds are contributing to 8 to 10 ft combined seas in this area,
along with a component of longer- period NW swell. NW swell of 8
to 9 ft lingers north of 20N and east of 120W toward the coast of
Baja California. Gentle breezes and moderate seas in a mix of
swell are noted elsewhere.

The swell north of 20N and east of 120W will subside this
evening. The fresh trade winds and the remaining 8 to 10 ft seas
in the trade wind belt will gradually subside through late Wed as
the high pressure north of the area weakens. Looking ahead, a
new set of NW swell with rough seas may arrive by the end of the
week and into next weekend north of 25N. Moderate winds and seas
will persist elsewhere through Sun.
