OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Moderate to fresh S-SW winds are noted across most of the Gulf 
of California N of 25N, where seas are 3 to 5 ft. Otherwise, 
weak high pressure prevails west of Baja California with gentle 
to moderate NW winds. Gentle W-NW winds dominate the remainder of
the offshore waters, with seas of 4 to 7 ft in mixed long period
swells.

High pressure will prevail west of Baja California through the 
week with fairly tranquil marine conditions anticipated.

Light to gentle winds prevail north of the monsoon trough, with 
moderate to fresh S-SW winds south of the monsoon trough. Seas

Mainly gentle winds will prevail north of the monsoon trough, 
with moderate to fresh offshore pulses expected nightly in the 
Papagayo region. Moderate to fresh S to SW winds south of the

trough, along with gentle to moderate trades. Gentle to moderate 
southerly winds prevail south of the monsoon trough, moderate to 
locally fresh east of 125W. Seas of 5 to 8 ft in mixed long 
period swell dominate the waters. Little overall change in marine
