Traveller notes on Dilijan in September
Notes from nearby Yerevan (69 km away)
Dilijan doesn't have its own notes for September yet — these are about Yerevan, close enough to share the season.
September is among the forum's favourite months in Armenia: pleasant, clear-skied, and harvest season. Yerevan runs near 27°C by day but drops to about 13 at night, and posters warn it can turn windy and cool after dark, so a jacket earns its place even in a warm month. Rain is possible but rare, barely a day across the month. Regulars specifically recommend the second half of September, when the open-air cafés and restaurants are still running late, and late September into early October for photography, when the air goes clear.
