The climate of Azerbaijan can be described as continental influenced climate with warm summer and very cold, dry winters. It can be divided in three different climate zones; one north of the mountainous regions, one south of them, and along the coast of the Caspian sea.

Temperatures during the summer months vary between 20°C and 30°C. summers in Azerbaijan are often warm and sunny with dry periods, but sometimes heavy cloudbursts and severe thunderstorms can occur, and can cause local flashfloods and damage.

During the winter months of December through March it gets quite cold, with daily temperatures far below zero and (little) snowfall. The mountainous regions of Azerbaijan are known for severe weather conditions and extremely cold weather that descends upon them during the winter months, with very strong winds and snowstorms. The Sheki Zakataly region lies just south of the mountains and has quite different conditions than the northern regions, with less rain, warmer summers and a bit milder winters. The coastal areas are significantly warmer then the northern mountainous portion of Azerbaijan, due to the tempering effect of the Caspian Sea.

Required clothing:
Lightweight clothes with occasional rainwear are advised for the summer months, Medium- to heavyweight is neccesary during the winter. Be prepared for very low temperatures and hazardous conditions in the mountainous areas in the winter, -30°C and lower! Wherever you go, take a sweater for cool evenings, the difference between maxima and minima can vary significantly.

Koeppen-Geiger classification:
