Strong low pressure system is moving through Northern California tonight with very cold temps, low snow levels and a lot of wind. Ocean has responded to the system offshore - with Cape Mendo showing 17ft at 12-13 second intervals. Not sure all the models have a good handle on this swell but look for deepwater in the 6-10ft range by sunrise tomorrow. NW wind the rule and very cold temps for the early morning sessions. Swell will quickly trend down through Thanksgiving Day and into Saturday - winds may improve for the morning sessions. By Sunday, another large swell will roll in pushing deep water heights back up in the 8-12ft range. We may see a fairly extended run of elevated surf through Dec 5th if the models are correct as the El Nino infused North Pacific gets energized with low pressure systems lining up and ramping up. Plenty of swell on tap - check the winds and know your spots. Happy Thanksgiving and cya in the water.
