Azerbaijan has an extremely diverse climate, with nine climatic zones present in the country. The three main climatic zones can be divided into the area north of the mountainous regions, the area south of the mountainous regions and the coast of the Caspian Sea.
There are substantial temperature variations between the coastal and mountainous regions, where it snows in the winter. Generally, Azerbaijan experiences hot summers and cold winters. Summers in the capital of Baku, which lies at the coast, are hot and humid and winters are cool and wet.
Lightweight clothing is sufficient for summer, but it’s a good idea to always have a sweater for the cooler evenings. The winter months require more heavyweight clothing and an umbrella.
