OFFSHORE WATERS WITHIN 250 NM OF MEXICO Surface ridging anchored by a 1027 mb high near 30N131W is maintaining fresh northwest winds along the Baja California offshore waters, with wave heights of 3-5 ft due to a south to southwest swell. Along the Gulf of California, fresh to strong northwest winds continues all the way to the Nayarit offshore waters with wave heights of 5-6 ft.
