Baku in late April and early May experiences mild to warm temperatures, averaging 15-23°C (59-73°F), with occasional breezes from the Caspian Sea. This calls for layering light but versatile clothing.
Wear lightweight shirts or polos paired with comfortable chinos or jeans. A light jacket or sweater is recommended for cooler mornings and evenings, especially near the sea.
Choose comfortable walking shoes or casual sneakers as you may walk on cobbled streets. Sunglasses and a hat are advisable to protect from the spring sun. An umbrella could be useful for occasional spring showers.
For dining out or visiting cultural sites, business casual wear such as a button-down shirt and dress shoes is suitable. Lightweight fabrics like cotton or linen are ideal.
