Past few days featured east winds, large clean waves at Ocean Beach and other spots along the Central/North Coast. Sat picture tells the story of change ahead. A very strong storm system is moving onshore today with gale force south winds forecast and victory at sea conditions expected. Swell is going to jump back up into the 14-20ft range - (biggest north of Cape Mendocino) - and stay large through the weekend. In fact don't look for deep water swell heights to drop much below 10 ft through Monday with back to back West swells rolling through here as a result of a very active and strong storm pattern in the Gulf of Alaska, East and West Pacific. El Nino is ramping up as we move more into the winter season. Everything we've had so far in terms of rain and swell is just a teaser for the Jan-Mar time period when the current El Nino will be in full bloom and maturing. Strong south winds today 20-30kts gusting to 45kts, and then pretty much light south winds through Sunday. Spots that like that wind direction will be clean, but large. Cya in the water.
