Moderate winds are off the Cabo Corrientes/Jalisco coast with light to gentle winds elsewhere over the Mexican offshore waters. Seas range 4 to 6 ft. For the forecast, a new set of NW swell associated with a cold front will move across the Baja California Norte offshore waters Mon evening and reach the Cabo San Lucas offshore waters by Wed night into Thu.

Strong SW winds are also expected in the northern Gulf of California ahead of the front on Wed and into Wed night. Moderate to fresh N winds will prevail in the Gulf from Thu into Thu night. Meanwhile, strong N winds will begin in the Gulf of Tehuantepec on Mon and reach near gale force winds Tue evening through Wed night. Winds will gradually diminish on Thu.
