The clear and seasonably warm weekend leading into Christmas will transition into something a little more wintery heading into the holiday.
Christmas Eve will see strong to gale-force (25 to 38 mph) northwesterly winds, cooler temperatures and most importantly a few scattered rain showers as a trough of low pressure moves into Central California. Snow levels are expected to drop to around 5,500 feet with about one foot of snow. Rain showers and gale-force northwesterly winds are expected to continue into Christmas Day.
Dry, clear and warmer weather with gusty Santa Lucia (northeasterly) winds are forecast Wednesday, followed by strong to gale-force (25 to 38 mph) northwesterly winds Thursday into Friday. The long-range models are advertising a wet January.
An 8- to 10-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 17-second period) is forecast along our coastline Sunday afternoon into Tuesday. A 5- to 7-foot northwesterly (310-degree, deep-water) sea and swell (with a 7- to 12-second period) is forecast along our coastline Wednesday into Thursday morning, increasing to 8 to 10 feet (7- to 11-second period) on Thursday afternoon into Friday.
Seawater temperatures will range between 57 and 60 degrees through Monday, decreasing to 52 and 55 degrees on Tuesday into Friday.
