What is my hardiness zone (temp shown below)

[Itsmedata]

My area is in north greece, the coldest it gets is -6c/20f, the mean min temperature is like around 30f, if i understand it doesnt this means its supposed to be borderline 10a? Even though most subtropics cant survive even -6c for some nights.
Data from 2022
Coldest temp of jan -6,5
Coldest temp of feb -1,4
Coldest temp of dec 8,7

this is the best USDA-hardiness map I have found of europe that includes Greece:

yes i have seen map, most maps except this one say 9a, this says borderline 8b-9a  but i asked cuz i was thinking there might be some mistake

I am on the border of 10a and 9b. In my case, as much as I wish it were 10a it is definitely not. Most accurately you are probably in Zone 9a. Lean towards the colder zone for your first plantings and experiment from there. As climate change progresses, you will probably need to worry less and less. I have seen notable changes in just 10 years.

Zone 9: The minimum average temperature range is 20°F to 30°F.
Zone 9a: The minimum average temperature range is 20°F to 25° F.
Zone 9b: The minimum average temperature range is 25°F to 30°F.

our minimum average temp is 32f in january, i know things like prickly pear, persimmon, loquat and of course figs, pomegranate etc i will start with feijoa, kiwi, blueberrys then progress into maybe normal guavas

Hi

Another Greek here. I have studied climate zones in Greece a bit and I'd say don't rely too much on that map. There is a better one here: http://hardiness.inforest.gr/ but even this one you should take with a pinch of salt.

Kavala is definitely not zone 10a. I would say 9a if you are less than a kilometer from the coast, or else 8b.
