Spring (April-May) is ideal with temperatures of 15-25°C. The weather is mild, gardens are blooming, and the risk of rainfall is minimal. This is considered the best season for outdoor exploration.
Fall (September-October) offers similar pleasant conditions with comfortable temperatures and lower humidity than summer. Days are sunny and perfect for walking and sightseeing.
Summer (June-August) brings hot, dry weather with temperatures reaching 28-35°C. The Caspian Sea is warm for swimming, but intense heat makes daytime sightseeing uncomfortable. Most locals escape to nearby mountains during peak summer.
Winter (November-March) is mild compared to northern climates, with temperatures around 5-10°C, but includes occasional rain and cold winds off the Caspian. Fewer tourists mean better access to attractions.
Avoid late July-early August due to extreme heat, and major Islamic holidays when some attractions may have limited hours.
