Since for each 1000’ of elevation the temperature drops from 3 to 5 degrees Fahrenheit with 5 being the norm for clear skies it can be 25 degrees cooler than the valley floor. Even though it can get cold, it rarely snows in the Sierra Norte. When the clouds come usually it warming and it rains. Although every place on this earth is unique the upper elevations of the Sierra Norte feel a bit like coast range in southern Oregon near Ashland with a touch of California’s Northern Sierra thrown in, but then there are the tropical plants such as bromeliads.
