The strong ridge of high pressure responsible for the record high 105 degree reading in Paso Robles on June 7 has moved off to the east.
An upper-level low pressure system will continue to move northward along the California coast today. This system will produce a deep marine layer with areas of fog and drizzle. The North County will clear later this morning and the coastal valleys by this afternoon. However, the beaches will remain overcast through the day. Today’s temperatures will only reach the 70s in the North County and coastal valleys with 60s at the beaches.
This low pressure system will also bring the threat of thunderstorms with the potential of dry lightning in the Sierra Nevada; which will increase the fire danger in that area.
Warmer temperatures then return to the Central Coast on Tuesday with temperatures slowly warming to seasonal levels by the end of the week. Typical coastal low clouds and fog will develop during the night and morning hours. However, increasing northwesterly winds will produce a greater amount of clearing along the shoreline, especially the southwesterly facing beaches of Cayucos, Avila and Shell Beach. At this time it appears the mostly fair and seasonable weather will hold into the following week as well.
Monday’s Surf Report:
Today’s 4- to 6-foot northwesterly (295-degree deep-water) swell (with an 8- to 11-second period) will remain at this height and period through Tuesday.
Increasing northwesterly winds along the California coastline will produce a 5- to 7-foot northwesterly (300-degree deep-water) sea and swell (with a 5- to 9-second period) on Wednesday. This northwesterly sea and swell will build to 6 to 8 feet with the same period on Thursday and will remain at this height and period through Saturday.
Arriving from the Southern Hemisphere:
A 1- to 2-foot southern Hemisphere (195-degree deep-water) swell will arrive along the Central Coast on Tuesday and Wednesday.
Seawater temperatures will range between 54- and 57-degrees through Wednesday, decreasing to 51- and 55-degress on Thursday through Sunday.
