OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface ridge is building eastward to around 20N113W. The 
associated pressure gradient supports moderate NW winds west of 
Baja California. Mainly light to gentle winds and 4-7 ft seas 
prevailelsewhere. Moderate to fresh NW winds are expected west

Moderate to fresh SW winds prevail south of the monsoon trough 
along with 6-8 ft seas in southwesterly cross-equatorial swell. 
Gentle to moderate winds are north of the trough axis along with 
seas of 4-6 ft. The winds in the Papagayo Region could become 
fresh to strong Sun night and Mon.

REMAINDER OF THE AREA...

A ridge extends E-SE from high pressure centered near 33N140W to 
just west of the Revillagigedo Islands. The associated pressure 
gradient is supporting fresh trade winds from 10N to 17N west of

to fresh trade winds and 5-7 ft seas prevail elsewhere north of 
the convergence zone, west of 120W.
 
Moderate southerly flow prevails S of the monsoon trough axis. 
Long-period southwesterly swell dominates the waters south of 
12N and east of 115W, in 6 to 8 ft seas. Southerly swell 
entering the area will maintain 6-8 ft seas south of 10N.
