Dense Ground Fogs are a trademark of the onset of autumn along San Diego's coastal strip. Fog materializes during the night and early morning hours when moist marine air that has settled in valleys and low areas is chilled below the dew point These ground fogs are distinct from the low overcast (“marine layer") that usually blankets the coastal zone on late-spring and summer mornings.
Spider Webs, decorated with myriads of tiny dew droplets, are a beautiful sight on foggy autumn mornings. Look for them in San Diego's wild canyons and park areas, or in your own backyard.
The Waxing Crescent Moon makes its first easily observed appearance in the evening sky on Monday, October 3. At around 20 minutes after the time of sunset look low in the southwestern sky, to the left of where the sun went down, and you will spot the moon's thin crescent shape. Unlike in the spring season when the evening crescent moon “smiles" with upturned cusps, the autumn crescent-moon cusps point well to the left — toward the southern part of the sky.
