Weather Watch

SLO County weather forecast for the week of Oct. 27

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

A pattern of moderate to fresh (13- to 24-mph) Santa Lucia (offshore) winds developing during the night and morning hours, shifting out of the northwest and increasing to fresh to strong (19- to 31-mph) levels during the afternoon hours along the coastline, should produce clear skies, warmer temperatures and lower relative humidity levels through Wednesday. Today’s maximum temperatures are forecast to reach the mid- to high 70s throughout San Luis Obispo County, increasing to the low to mid-80s Tuesday and Wednesday.

A persistent onshore flow Thursday should allow for night and morning marine low clouds to develop along the coast and coastal valleys. 

After nearly 190 days without any significant rain, wet, cool and unsettled weather could come as early as Friday (Halloween) as an area of low pressure will drop out of the Gulf of Alaska and progress through the Central Coast. Details remain unclear at this time; however, the storm has potential to bring widespread rain and wind to San Luis Obispo County through Saturday.   

Surf report

Today’s 5- to 7-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 11-second period) will decrease to 4 to 6 feet (with a 7- to 11-second period) Tuesday and remain at this height and period through Wednesday. A 4- to 6-foot west-

northwesterly (290-degree, deep-water) swell (with an 8- to 11-second period) is forecast along our coastline Thursday into Friday. Combined with this swell, will be 2 to 3 foot southerly seas on Friday.

A 9- to 11-foot northwesterly (315-degree, deep-water) sea and swell (with a 5- to 15-second period) will arrive along our coastline this weekend.    

Seawater temperatures

Seawater temperatures will range from 57 to 61 degrees through the weekend.
