Climate overview
Armenia (38°50′–41°20′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 long, cold winters and warm, dry summers. Yerevan (around 1,000 m) averages roughly −4°C in January and 25°C in July, with afternoon peaks reaching 35–40°C. The Lake Sevan basin is notably cooler, and mountain valleys can see January means at or below −15°C with heavy snow. Annual precipitation is lowest on the Ararat plain, 250–400 mm, and rises to 800–1,000 mm in the northern and southwestern highlands; much of the rain arrives as summer convective storms. Strong foehn (kazald) winds sweep through in spring.
