This time of year in Southern California the landscape is generally blanketed by cloud in the mornings, a marine layer from the Pacific Ocean that burns off around 11:00 am. Because of the cloud, the daily temperatures are held down and the heat rarely builds up over 100 f (38 c) in the afternoon. It is a general rule that when the morning marine layer lasts into July, the summer has fewer days over 100 degrees f.
It is a mixed bag. On one side, the days are not unbearably hot. On the other, we don’t get to see much cloud definition like that in this photograph, a view to the north from Mount Rubidoux.
