Baku in September

April through May gives you mild weather and blooming trees without the summer crowds that started showing up in recent years. September and October deliver the same pleasant temperatures with the bonus of harvest season in nearby wine regions. Summer gets brutally hot — 40°C days with humidity from the Caspian Sea. Winter brings strong winds off the water that cut through any jacket you own. But here's the thing about off-season visits: hotel prices drop by half, restaurants aren't rushed, and you get the city mostly to yourself. January snow against the Flame Towers creates some dramatic photo opportunities if you can handle the cold.
