Moderate Santa Lucia winds produced clear skies along most San Luis Obispo County beaches on Wednesday but Avila Beach did experience some low clouds with areas of fog.
Strong to gale force winds should allow for clear skies through Wednesday evening.
An air quality warning is in effect for San Luis Obispo, Pismo Beach, Morro Bay, Cambria, and San Simeon through 7 p.m. Wednesday.
The air quality is being impacted by strong winds blowing sand from the Nipomo Mesa into the air, which can cause serious health issues for the lungs and respiratory system.
The strong winds are also prompting an extension to Tuesday's wind advisory on Highway 101 in the Gaviota and Refugio area of Santa Barbara County. The advisory could mean hazards for high profile vehicles traveling through the area.
Night and morning marine low clouds accompanied by slightly cooler temperatures are likely Thursday.
A persistent marine layer with fog and mist will begin Friday and carry on through Tuesday at the beaches.
The PG&E Fire Danger warning for Wednesday was high along the coastline and coastal valleys, while inland valleys are rated very high danger.
