Chill Hours

Cold chill hours can be a little confusing. Basically they are the number of hours below 45°F subtracting the number of hours above 60°F between the months of November and February.

If you live in or around any of these areas, your average chill hours are:

  • Malibu, Ventura, Santa Barbara: ± 300 Hours
  • San Fernando Valley, Fillmore, Simi Valley: ± 800 Hours or less
  • Santa Clarita, Lancaster: 800 Hours or more

There is no simple test for "Chill Hours" and they are calculated as an average. Each winter season differs in total chill hours accumulated, which can affect fruit production. Most of the fruit trees we carry at Otto & Sons are classified as low chill requirement and are better matched for our Southern California chill hours.
