Besides the fog, the smoke from nearby wildfires continues to remain in the forecast. These conditions will also continue to influence daytime highs as the smoke is limiting the heating of the ground during the day, which in turn is keeping surface temperatures cooler. However, as conditions improve, the daytime highs will gradually begin to increase. Temperatures for the inland valleys will be in the 80s and 90s and the coastal valleys will be in the 70s and 80s. As for the coast, the marine layer could keep temperatures on the cooler side and from the mid to upper 60s.
According to the San Luis Obispo Air Pollution Control District, moderate to unhealthy air quality levels remain in the forecast for Monday. The air pollution control district for Santa Barbara County is forecasting similar conditions. Between the two counties, it is being advised that those with sensitivities or pre-existing health conditions limit time outdoors.
The winds will be mild to moderate Monday ranging from 10 to 20 miles per hour. Southwesterly winds are expected to increase to 20 miles per hour across portions of the interior valleys Monday, while Pismo Beach and other coastal locations will have max. northwesterly wind speeds closer to 10-15 miles per hour. However, sundowners are expected to stay in the forecast through mid-week for the south coast in Santa Barbara County with wind gusts from 20-25 mph.
