OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A 1026 mb high off the southern California coast continues to
channel moderate to fresh NW to N winds across the waters west
and southwest of Baja California peninsula, and also over the
northern Gulf of California. Seas range from 6 to 9 ft near Baja
and across the Gulf of California. Gentle to moderate winds with
4 to 6 ft seas are present across the southern Mexican offshore
waters, except fresh to strong winds and seas at 5 to 6 ft near
the Gulf of Tehunatepec.

For the forecast, moderate to fresh NW to N winds will persist 
west of Baja California Norte through Sun afternoon, and west and
southwest of Baja California Sur through Sat afternoon; then 
stay at gentle to moderate most of next week. Fresh to strong 
northerly winds are expected over the northern Gulf of California
and near the Gulf of Tehuantepec tonight, then become gentle to 
moderate by Fri morning. Long-period NW swell will continue over 
the waters west of Baja California through Mon, except S of Cabo 
San Lazaro where it will subside beginning late on Sat. 

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

Fresh to strong easterly winds with 5 to 7 ft seas are occurring
near the Papagayo region and offshore from southern Nicaragua.
Gentle to moderate winds and seas at 6 to 7 ft are evident
between the west of coast of Colombia and Galapagos Islands.
Light to gentle winds and seas of 4 to 5 ft prevail elsewhere.

For the forecast, fresh to strong easterly winds across the 
Papagayo region and offshore the southern Nicaragua waters will 
gradually diminish to southerly between gentle and moderate by 
late Sat afternoon. Long-period moderate S to SW swell across the
region will subside to gentle toward midweek next week.

REMAINDER OF THE AREA

Moderate to fresh trades are N of the ITCZ to 26N and W of about
118W. Long-period NW to N primary swell over this area is
maintaining seas at 7 to 8 ft. Gentle to moderate E to SE winds 
along with seas of 5 to 7 ft seas in moderate long-period S to 
SW swell are noted elsewhere.

For the forecast, northerly swell with seas at 7 to 8 ft will 
continue across the western forecast waters over the next few 
days, mostly N of 09N and W of 120W. Seas will increase slightly
to 9 ft on Sat over this area and subside by early next week. 
Otherwise, southerly swell should keep 5 to 7 ft seas across the
remainder of the basin through the weekend.
