Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
A weak low-pressure system is expected to move through the Central Coast today into Tuesday morning with plenty marine low clouds, fog and areas of coastal drizzle. In fact, this drizzle may produce measurable precipitation along the beaches tonight in the Tuesday morning. June Gloom starts right on cue and the beaches of San Luis Obispo County should remain overcast today.
This low-pressure system is expected to also produce cooler temperatures, with the North County reaching the low 80s, and the coastal valleys ranging from the high 60s to the low 70s. Maximum temperatures along the beaches should range between the high 50s and the low 60s.
A high-pressure ridge is expected to build across the Central Coast on Wednesday through Friday for warmer weather with less marine clouds. However, the coastline should continue to see night and morning low clouds, fog and areas of drizzle. Potentially warm to hot weather is expected to develop in the North County with some locations reaching the triple digits by Friday. The coastal valleys, such as San Luis Obispo, should warm to the low 80s, while the beaches will remain cool.
Cooler weather develops this weekend, first in the coastal regions Saturday and then across the North County on Sunday. This cooling trend is expected to continue into early next week with plenty of night and morning low clouds and fog.
Today’s charts and models are showing a stable weather pattern over the Pacific Ocean with little change indicated through this week.
Consequently, today’s a 3- to 5-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 11-second period) will remain at this height and period through Thursday morning, increasing to 4 to 6 feet with the same period Thursday afternoon through Sunday.
A 1-foot Southern Hemisphere (210-degree, deep-water) swell (with an 18- to 20-second period) will arrive along our coastline Sunday, building to 2 to 3 feet (with a 16- to 18-second period) next Monday.
Seawater temperatures will range from 52 to 54 degrees through Sunday.
