Tropical Weather Discussion

0405 UTC Wed Mar 25 2026

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
0345 UTC.

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

A surface trough extends from low pressure in northern Colombia
southwestward to 08N78W and to 05N90W, where it transitions to 
the ITCZ and continues to 06N110W to 04N125W to 03N135W and 
to beyond 03N140W. Scattered moderate convection is within 
120 nm north of the ITCZ between 101W-113W, within 60 nm 
north of the ITCZ between 95W-100W and within 60 nm north 
of the ITCZ between 118W-124W.

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

Light to gentle northwest to north winds are over the waters 
west of Baja California, and mostly light and variable winds over
the remainder of the offshore waters W of Tehuantepec. Seas are 
in the range of 4 to 6 ft in northwest swell over the offshore 
waters west of Baja California, and 3 to 4 ft over the remainder 
of the Mexican offshore waters. In the Tehuantepec region, fresh 
to strong northerly winds prevail with seas to around 8 ft. In
the Gulf of California, winds are generally light and variable
except in the central part of the Gulf where gentle west winds 
are present. Seas are 3 ft or less in the Gulf.

For the forecast, high pressure west of Baja California will 
continue to support the mostly light to gentle northerly wind 
flow over the waters west of Baja, and mostly light and variable 
winds over the remainder of the offshore waters through the 
forecast period, with the exception of winds pulsing to moderate
speeds north of Cabo San Lazaro Wed night through late Thu 
night, then north of Punta Eugenia through the rest of the 
forecast period. Northwest swell will build seas to 9 ft north 
of Punta Eugenia Thu through Fri night before subsiding. Fresh to
strong north gap winds in the Gulf of Tehuantepec will pulse 
nightly through the rest of the week with rough seas. A frontal 
boundary will move across the Gulf of America this weekend. The 
pressure gradient in the Tehuantepec region will tighten leading 
to gale-force northerly winds there north of 14N beginning Sat 
night.

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

A broad subtropical ridge centered north of the Caribbean Sea is 
currently allowing for fresh to strong northeast to east winds 
in the Gulf of Papagayo region as noted in the latest scatterometer
satellite data. Seas with these winds are 4 to 6 ft. Farther 
east, moderate north to northeast winds are in the Gulf of 
Panama reaching southward to near 06N. Seas are 3 to 5 ft with 
these winds. Elsewhere, light to gentle winds and moderate seas 
prevail.

For the forecast, the fresh to strong northeast to east winds 
in the Gulf of Papagayo region will pulse nightly going into the
upcoming weekend along with moderate to rough seas. Moderate to
occasionally fresh north to northeast winds will pulse in the 
Gulf of Panama during this time. Gentle breezes and moderate seas
will prevail elsewhere. 

...REMAINDER OF THE AREA...

The pressure gradient between modest high pressure north of 16N 
and west of 121W, and lower pressure near the ITCZ is currently 
sustaining mostly moderate trades from 05N to 18N between 129W
and 135W, also from 05N to 13N between 113W and 129W, and from
06N to 13N west of 135W. Seas are 5 to 7 ft within these areas
of trades. Elsewhere, latest scatterometer satellite data
indicates light to gentle northeast to east winds. Seas are 
4 to 6 ft elsewhere primarily due to a long-period northwest to 
north swell. The tail-end of a cold front just touches 30N140W,
and stretches well southwestward from there as a dissipating 
stationary front.

For the forecast, fresh to strong northeast to east winds will 
develop north of about 26N and west of 119W Thu through Fri as 
the pressure gradient tightens between a ridge building southward
across the north-central waters, and a low pressure system, with 
attendant trough lifting northward west of the area near 145W. 
Seas are expected to build to 8 to 10 ft over this part of the 
area.
