Why is Yerevan mild in May?
Yerevan's May heat is driven by the Asian summer monsoon system, as the low-pressure cell that forms over the heated landmass draws warm, humid air from the oceans. The result is temperatures averaging 21°C with high moisture in the air. Overnight temperatures remain elevated at 8°C, as clouds and humidity prevent the earth from radiating heat away after sunset. Climate data: Open-Meteo ERA5 (1991–2020).
