The hardiness map you are using is incorrect. I find the 2015 Arbor Day Hardiness map to be most accurate as it reflects a longer period of average. After looking at it, it does indeed reflect 40-50 year periods quite well at official weather stations.

Wonderful detailed explanation ❤ palms 🌴 are so beautiful for landscape
