Here is this weeks weather forecast by PG&E meteorologist John Lindsey.
A weak 1,011-millibar cut-off low-pressure system will move over the Central Coast today and remain nearly stationary through Friday.
The system will produce gentle (8- to 12-mph) southerly winds along with night and morning low clouds, fog and perhaps drizzle.
Naturally, this marine layer will also bring cooler temperatures along the beaches and coastal valleys.
Temperatures in the North County will remain warm through Tuesday under mostly clear skies, and then the marine layer will deepen and move inland during the night and morning hours Wednesday through Friday. This condition will produce cooler conditions throughout San Luis Obispo County.
Slightly warmer weather is expected Saturday into Sunday in the North County. However, the northwesterly winds will increase in response to a cold front moving across Northern California and will keep temperatures the beaches and coastal valleys below seasonal norms.
Unfortunately, April is taking the same path as January, February and March, with below-average rainfall.
In fact, dry weather is forecast to persist through the end of the month.
An extended and usual period, especially for this time of year, of gentle (8- to 12-mph) southerly winds will develop along our coastline today and will continue through Friday.
This relaxation of the northwesterly winds will allow a 3- to 5-foot northwesterly (310-degree deep-water) swell, with an 8- to 11-second period, to develop along our coastline today, decreasing to 3 to 4 feet with the same period Tuesday through Wednesday.
This northwesterly (310-degree deep-water) swell will further decrease to 2- to 3- feet (with a 9- to 11-second period) Thursday and remain at this height and period through Friday.
Increasing northwesterly winds will generate a 3- to 4-foot northwesterly (325-degree shallow) seas, with a 4- to 6-second period, Saturday and Sunday.
Seawater temperatures will range between 51 and 53 degrees today, increasing to 52 and 54 degrees Tuesday through Wednesday. The seawater temperatures will continue to warm to 53 and 55 degrees Thursday through Friday.
