Gulf of California: Light and variable winds will prevail over the Gulf of California during the next several days, except for in the northern Gulf where fresh to near gale force SW to W gap winds will pulse in the northern Gulf of California through the week, with the strongest winds Thu night. A low pressure system of 1010 mb is N of the area 35N123W and extends a weak cold front into the waters near 30N120W. This low will move inland over California tonight while the trailing front gradually dissipates. Another weak cold front will approach Baja California Norte by the end of the week with little impact. Otherwise, high pressure ridging from NW of the area will prevail with moderate to occasionally fresh winds W and NW of Cabo Corrientes, and gentle to moderate winds S and SE of Cabo Corrientes. Seas will be mainly 4 to 7 ft. Ongoing agricultural burning in SE Mexico and Central America continues, however, associated smoke and haze has diminished somewhat as have impacts to visibility.

Gulf of Papagayo: Offshore winds will occasionally pulse to fresh during the overnight and early morning hours. Light to gentle onshore winds with seas in the 4 to 6 ft range will continue elsewhere through Thu night. A significant SW swell event will move into the Ecuador offshore waters by Thu night.
