SLO County weather forecast for the week of June 10: Hot temperatures continue
Get used to the sun, San Luis Obispo County.
Increasing high pressure over California will produce moderate to fresh (13 to 24 mph) Santa Lucia (northeasterly) winds to start the week.
These offshore winds will produce low relative humidity levels, clear skies and much warmer temperatures throughout San Luis Obispo County. Over this time frame, the inland valleys (Paso Robles) will reach triple-digit levels, while the coastal valleys (San Luis Obispo) will hit the mid-80s.
The beaches will range between the high-70s to the mid-80s with the warmest temperatures occurring during the late morning hours, before the onshore flow brings cooler marine air to shoreline during the afternoon hours. Gentle to moderate (8 to 18 mph) westerly winds on Monday into Wednesday will allow a persistent marine layer with night and morning fog and mist to develop along the coastline.
This condition will produce cooler temperatures, especially along the beaches. Increasing northwesterly winds, cooler temperatures and more sunshine along the beaches is forecast on Thursday into Friday. However, areas of heavy drizzle could develop during early morning hours along the northwesterly facing beaches.
Surf report
A 4- to 6-foot northwesterly (300-degree, deep-water) swell (with an 8- to 11-second period) is forecast along our coastline on Sunday, decreasing to 3 to 5 feet with the same period on Monday through Wednesday. Increasing northwesterly winds will generate 3- to 5-foot northwesterly (310-degree, deep-water) sea and swell (with a 5- to 11-second period) on Thursday and Friday.
Arriving from the Southern Hemisphere: A 1- to 3-foot Southern Hemisphere (175-degree, deep-water) swell (with a 14- to 17-second period) will arrive along our coastline on Sunday and will continue through Wednesday. A higher-energy Southern Hemisphere swell could arrive along our coastline on June 16.
