 SEA/SWELL:

 A 2- to 4-foot northwesterly (310-degree, deep-water) sea
 and swell (with a 5- to 14-second period) is forecast along
 our coastline today into Friday.

 A 3- to 5-foot northwesterly (290-degree, deep-water) swell
 (with an 8- to 11-second period) is forecast along our
 coastline on Saturday into next Thursday. 

 Arriving from the Southern Hemisphere: 

 A 1- to 2-foot Southern Hemisphere (180-degree, deep-water)
 swell (with an 18- to 20-second period) will arrive along
 our coastline today, increasing to 2- to 3-feet (with a 16-
 to 18-second period) on Friday into Saturday. This Southern
 Hemisphere swell will gradually decrease on Sunday into
 Monday. 
 
 ATMOSPHERIC CONDITION:

 The marine layer will gradually clear from the coastal
 valleys of San Luis Obispo and Santa Barbara Counties
 later this morning. Strong to gale-force (25 to 38 mph)
 northwesterly winds along the coastline this afternoon
 will produce clearing along the beaches. 
 
 Today's high temperatures in the North County are expected
 to range between to mid to high-90s. The coastal valleys
 will reach the low 80s, while most of the beaches will
 be in the 60s, the southerly facing beaches of Avila and
 Shell Beach will reach the 70s. 

 Subtropical moisture will move northward over the Central
 Coast today into Friday and will produce a few mid-
 to upper-level clouds and chance of thunderstorms in the 
 Sierra Nevada. Otherwise, night and morning marine low 
 clouds with pockets of fog and mist will continue to
 develop in the coastal regions. Overall, typical
 summertime weather. 

 High temperatures will warm on Friday into Sunday as high
 pressure re-strengthens over the desert southwest with
 maximum temperatures reaching triple-digit levels in the
 North County. 

 Temperatures should decrease back to near seasonal averages
 with extensive night and morning marine low cloudiness near
 the coast next week.

 WILDFIRE DANGER RATINGS: 

 Fire danger ratings have decreased due to marine low clouds
 and cooler temperatures along the beaches and in the coastal
 valleys, but fire danger will remain seasonably high across
 the inland valleys. Fire index ratings are at low to medium-
 levels along the beaches and coastal valleys and at high 
 levels in the inland valleys of San Luis Obispo and Santa
 Barbara Counties.
