Here are some important facts about the local weather, covering temperature, rainfall and sunshine hours throughout the year.
Note that the south end of Scottsdale and Phoenix are at about 1,000 ft elevation. Araminta House is at about 2,000 ft elevation. Going north the elevation keeps climbing with the higher elevations in North Scottsdale and Cave Creek reaching 2,500 ft and above. That means our actual temperature is sometime higher and sometimes lower then you find further south at lower elevations.
If you were to continue north a couple if hours you would reach Sedona and then Flagstaff with elevations of 7,000 ft and above, creating a completely different climate zone. For the horticulturist it may be interesting to know that we are in hardiness zone 9.
