Climate
The annual precipitation average is about 50.8 to 88.9 cm. The summer temperatures can get up to 100 degrees Fahrenheit, while winter can be as cold as -40 degrees Fahrenheit (Regents of the University of California). The best time of the year to go is in the spring or in the summer. This is because these are the times when it is not so cold, and has some rains. Also, all the flowers are in bloom at this season.
