SUNSET PLANT HARDINESS ZONES
2019
  The Idyllwild area has several micro-climates. Pine-cove and Fern Valley are colder and should be considered Zone 7, unless your garden is nestled against sun-absorbing stones, and wind protected.
The lower areas and into the Garner Valley is between the two. For example, Zone 8's growing season says it start's in Mid-February. However, cold air sinks and GV can get overnight freezes until mid-May! The end of season indication of November is quite accurate for GV.
 

ZONE 7.
Growing season: May to early Oct. Summers are hot and dry; typical winter lows run from 23 degrees to 9 degrees F/-5 degrees to -13 degrees C. The summer-winter contrast suits plants that need dry, hot summers and moist, only moderately cold winters.

ZONE 8.
Growing season: mid-Feb. through Nov. This is a valley floor with no maritime influence. Summers are hot; winter lows range from 29 degrees to 13 degrees F/-2 degrees to -11 degrees C. Rain comes in the cooler months, covering just the early part of the growing season.

Both areas in our mountains can also expect some moisture due to a few monsoonal storms in late summer.
