Highs and lows for the Central Coast for the week of June 22.

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

Coastal low clouds were expected to redevelop during overnight hours, however the Santa Lucia (northeasterly) winds may be just strong enough Monday morning to clear the coastal stratus from many of the near-shore valleys and beaches.

Monday’s maximum temperature in the North County is expected to reach the mid-90s, while temperatures in the coastal valleys will hit the low 80s. High temperatures along the beaches will range from 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.

Beginning Monday night, the marine layer will return during night and morning hours; however, increasing northwesterly winds along the coastline during the afternoon hours will produce a greater amount of sunshine along the beaches during the late morning and afternoon hours through Wednesday.

A ridge of high pressure will build over the western United States and may bring warm conditions to the inland valleys of the Central Coast by the end of the week. As the ridge remains entrenched, subtropical moisture could be transported northward over most of California. This condition will increase the potential for thunderstorms.

Monday’s surf report

A 3- to 5-foot northwesterly (290-degree, deep- water) sea and swell (with a 5- to 8-second period) will develop along our coastline Thursday into Friday, decreasing to 2 to 4 feet (with a 7- to 11-second period) on Saturday into Sunday. Arriving from the Southern Hemisphere: Monday’s 1- to 2-foot Southern Hemisphere (205-degree, deep-water) swell (with a 16- to 18-second period) will remain at this height through Tuesday.
