Is my climate 9a? Info below

[Itsmedata]

I am from north greece, i live between 2 mountains. 1 mountain blocks the warm sea air and the other the cold north air, i have data froma a place 10km away from me (Which takes the north air because it isnt blocked from the mountain)

January is the coldest month averaging 9c highs and 2c lows
The average day in december which is our least sun month has 9 hours of sunlight and the sky is clear in average 12 hours every day of december.
February is the month with the most humidity and has 73%
August is our hottest month and has average highs 33c and average lows of 21c
This december was really hot we had days of 20c highs and the lowest it got was -1 to -2 for 10 hours in total in the whole december

I get my info from this sitehttps://wanderlog.com/weather/56986/8/eleutheroupoli-weather-in-august , anybody can check it.

Any help appreciated, i want to know if my zone is 9a, according to maps it is but like temperature isnt the only thing that plays a role as far as i know.

Yes your close to zone 9a. Check out "sunset zone" 8 or 9 in California may be closer to your climate and latitude.
