  SEA/SWELL:

 A 4- to 6-foot northwesterly (300-degree, deep-water) sea
 and swell (with a 5- to 14-second period) will develop 
 along our coastline this afternoon and will remain at this
 height but with a gradually shorter period through Friday.

 A 5- to 7-foot northwesterly (295-degree, deep-water) swell
 (with an 8- to 11-second period) is forecast on Saturday,
 decreasing to 4 to 6 feet with the same period on Sunday
 into Monday.

 A 5- to 7-foot northwesterly (310-degree, deep-water) sea
 and swell (with a 5- to 10-second period) will develop 
 along our coastline on Tuesday into next Wednesday. 

 Arriving from the Southern Hemisphere:

 A 1- to 3-foot Southern Hemisphere (190-degree, deep-water)
 swell (with a 16- to 18-second period) will arrive along our
 coastline on Friday into Monday. 
 
 ATMOSPHERIC CONDITION:

 For the last day of spring, high pressure over the western
 United States will continue to produce strong to gale-force
 (25 to 38 mph) northwesterly winds during the afternoon
 hours and areas of marine low clouds with pockets of fog
 and mist during night and morning hours along the coastline.

 Away from the coastal regions, the hottest weather of the
 year thus far will develop in the North County today
 into Saturday. 

 In fact, North County temperatures will warm to triple
 digit levels today into Saturday. In the coastal valleys,
 northwesterly (onshore) winds will keep high temperatures
 in the low to mid 80s, while the coastline will range
 between the high 50s and low 60s along the northwesterly
 facing beaches such as Morro Bay and Los Osos and low 70s
 along the southwesterly facing beaches such as Avila
 Beach & Cayucos.

 The marine layer is forecast to deepen Saturday night
 into Monday for a general cooling trend starting on 
 Sunday and continuing into Monday. Overall, not much
 change is expected for the rest of June.
