The low tonight here on the NOrthern California Coast is 52 degrees Fahrenheit

 I noticed as I was closing the shutters on the sliding glass doors that the air coming in the window above them was cold. So, I shut the window and decided to set the heater for 70 because it was already 70 in the house. Today was likely the coldest daytime temperature this summer and tonight is likely the coldest night time temperature this summer too. Interesting.
