Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
After many days of persistent Santa Lucia (northeasterly) winds that produced clear skies and well-above-normal temperatures along the coastal regions of San Luis Obispo and northern Santa Barbara counties, the winds have shifted out of the northwest.
This onshore flow will allow marine low clouds to develop along the coastline during the night and morning hours, with partial afternoon clearing. The marine layer should be deep enough Tuesday morning to produce areas of drizzle along the coastline. This onshore flow
also will provide lower temperatures.
Gentle to moderate (8- to 18-mph) Santa Lucia winds are expected Wednesday and Thursday morning, which could produce clear skies during the morning hours. However, marine low clouds are expected along the coastline during the late afternoon and evening hours, as high pressure will weaken in response to a passing low-pressure system.
Gentle southerly winds should produce persistent coastal stratus along the beaches, with mostly overcast skies and mild temperatures. Farther inland, clear skies are expected. We could do a rain dance, but I doubt it will help, because dry weather plans to stay here awhile. However, the long-range models indicate a possible return to wet and unsettled weather next week (Feb. 23-25), but details are unclear at this time.
Sunday’s 4- to 6-foot westerly (275-degree, deep-water) swell (with a 7- to 13-second period) will decrease to 2 to 4 feet (with a 7- to 12-second period) today. This westerly (275-degree, deep-water) swell will further lower to 2- to 3-feet (with an 8- to 11-second period) Tuesday.
A 4- to 6-foot westerly (270-degree, deep-water) swell (with a 14- to 16-second period) will arrive along our coastline Wednesday and will remain at this height (but with a 7- to 11-second period) Thursday. Combined with this westerly swell will be 2- to 3-foot northwesterly (310-degree, shallow-water) seas Wednesday and Thursday.
Seawater temperatures will range between 58 and 60 degrees through Friday, increasing to 59 and 61 degrees Saturday through next week. By the way, the normal seawater temperature for the month of February is 54 degrees.
