SLO County weather forecast for the week of June 15

Here is this week’s weather forecast by PG&E meteorologist John Lindsey:

A classic Central Coast late spring, early summer weather pattern has developed with a thermal low-pressure system over the great Central Valley of California combined with 1,026 millibar Eastern Pacific High firmly anchored several hundred miles to the west.

This condition will produce fresh to strong (19- to 31-mph) afternoon northwesterly winds along the coastline, which will scour out the marine layer during the late morning and afternoon hours, leaving behind sunny skies.

However, night and morning marine low clouds with pockets of fog and mist will continue to develop in the coastal regions. Historically, this tends to be a stable weather pattern and little change is expected through Sunday.

Maximum temperatures this week in the North County will reach the mid-90s, while temperatures in the coastal valleys will hit the high 70s and perhaps the low 80s. High temperatures along the beaches will range between the high 50s along the northwesterly facing beaches of Morro Bay, Los Osos, Montaña de Oro and Nipomo, and the low 60s along the westerly facing beaches of Cambria, Grover Beach and Pismo Beach. The southwesterly facing beaches of Cayucos and Avila Beach will reach the high 60s.

A strong ridge of high pressure could build over the Central Coast next week, which would result in higher temperatures across the coastal regions, especially at beaches as Santa Lucia (northeasterly) winds develop.

Monday’s surf report

Strong to gale-force (25- to 38-mph) northwesterly winds off the California coastline will generate a 5- to 7-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 9-second period) today through Friday, decreasing to 4 to 6 feet with the same period Saturday into Sunday.

Arriving from the Southern Hemisphere

A 1-foot Southern Hemisphere (205-degree, deep-water) swell (with an 18- to 20-second period) will arrive Sunday, increasing to 1 to 2 feet (with a 16- to 18-second period) next Monday and Tuesday.

Seawater temperatures

Seawater temperatures will range between 52 and 56 degrees through Sunday.

At PG&E, your safety is our first concern. Pruning trees next to power lines can be dangerous. Unqualified tree workers put their lives in jeopardy without specialized training or the proper insulated tools required to work near highvoltage power lines. If there is ever a question of your trees being too close to power lines, please call 800-743-5000.
