Climate overview
Armenia (between 38°N and 42°N) is a landlocked, mountainous nation in the South Caucasus with an average elevation of roughly 1,800 metres. Köppen types range from cold semi-arid (BSk) across much of the lowlands to humid continental (Dfb, Dsa) at higher altitudes. Mount Aragats rises to 4,090 m, Armenia's highest peak, while Lake Sevan, perched at 1,900 m, is the largest freshwater body in the Caucasus.
Continental patterns bring cold, snowy winters and hot, dry summers. Yerevan (around 1,000 m) has January lows around −8°C and July highs around 34–35°C, with afternoon peaks reaching 35–40°C. The Lake Sevan basin is notably cooler, and mountain areas see January means well below freezing with heavy snow. Annual precipitation is lowest on the Ararat plain, 200–400 mm, and rises to 700–1,000 mm in the high mountains; precipitation peaks in spring, while summers are dry.
