As far as I understand from the sentence I feel all alone without you (which poet likens it to feeling cold in that case), no matter what season it is. It's fairly hard to translate it into English. According to my research, it's a poem written by Levent Kaya. Unless your grammar and word knowledge are powerful enough to understand poems or something including figurative expressions my recommendation for you is not to spend your whole time with them. Time to time even native speakers may have problems to comprehend. That's how literature's supposed to be.

The season isn't culpable, It's your absence's coldness
