Tropical Weather Discussion

1005 UTC Fri Jun 12 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 0600 UTC surface analysis and satellite imagery through
0900 UTC.

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

The monsoon trough extends from 16N101W to 10N120W to 09N140W. 
Numerous moderate convection is noted from 02N to 11N between 
130W and 140W. 

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

A weak pressure gradient prevails across the area. With the weak
pressure gradient, light to gentle winds prevail over the open
waters off Mexico. Gentle to locally moderate winds are in the 
Gulf of California as well as off Cabo San Lucas. Seas are in the
5-7 ft range over the open waters off Mexico, and 3 ft or less 
in the Gulf of California. 

For the forecast, light to gentle winds will prevail across the 
waters of Baja California. Gentle to moderate, SW to S winds are
expected inside the Gulf of California and near the tip of Baja 
California Sur through the forecast period. Gentle to moderate 
NW to W winds will pulse each evening over the offshore waters 
of Baja California beginning Fri.

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

Gentle to moderate SE winds prevail between the Galapagos 
Islands and Colombia. Light to gentle variable winds are found 
elsewhere. Seas are in the 5-7 ft range between the Galapagos 
Islands and Colombia, reaching 8 ft south of the Galapagos 
Islands. Elsewhere, seas are in the 4-6 ft range.

For the forecast, gentle to moderate winds and moderate seas 
will prevail across the offshore waters into the weekend, except 
locally rough seas in new southerly swell near the Galapagos 
Islands today. Winds may pulse to moderate to locally fresh in 
diurnal offshore flow in the immediate Gulf of Papagayo and near 
the Gulf of Guayaquil during the upcoming weekend into early next
week. 

...REMAINDER OF THE AREA...

A ridge of high pressure enters the NW waters near 30N131W and 
extends SE to near 23N123W. Broad troughing prevails east of 
122W. The pressure gradient between the area of high pressure, 
and broad troughing is supporting moderate to fresh winds N of 
28N and W of 128W. The pressure gradient between the ridge and 
lower pressure within the monsoon trough is supporting gentle to 
moderate winds S of the monsoon trough to the Equator. Light to 
gentle winds are found elsewhere N of the monsoon trough. 
Northerly swell is bringing rough seas over the waters N of 28N 
between 126W and 136W. Mainly moderate seas are found elsewhere N
of the equator. S of 06N, seas are in the 7-8 ft range in S to 
SW swell. Scattered showers and isolated thunderstorms are 
ongoing from 02N to 09N between 87W and 122W. 

For the forecast, the pressure gradient will loosen W of the
elongated troughing, with winds diminishing there slightly 
through Fri. Winds will then be moderate or weaker across the 
entire open waters, except at least moderate to fresh near 
transient embedded low pressure areas along western portion of 
the monsoon trough. Northerly swells mixed with the longer period
southerly swells with seas of 7-9 ft will linger across the 
N-central waters through Fri night before decaying. Otherwise, 
moderate seas will dominate the open waters, locally rough in the
S-central waters through the end of the week, as well as near 
any of the embedded lows within the monsoon trough.
