Baku has a temperate semi-arid climate (Köppen climate classification: ''BSk'') with hot and humid summers, cool and occasionally wet winters, and strong winds all year long. However, unlike many other cities with such climate features, Baku does not see extremely hot summers and substantial sunshine hours. This is largely because of its northerly latitude and the fact that it is located on a peninsula on the shore of the Caspian Sea. Baku, and the Absheron Peninsula on which it is situated, is the most arid part of Azerbaijan (precipitation here is around or less than  a year). The majority of the light annual precipitation occurs in seasons other than summer, but none of these seasons is particularly wet.
