The best time to go to C A Rosetti is during the late spring (May to early June) or early autumn (September to early October) for pleasant weather and fewer crowds.During these shoulder seasons, you'll find comfortable temperatures for exploring the Danube Delta, with average highs around 20-25°C. The natural beauty of the delta is in full bloom in spring, making it excellent for birdwatching as migratory species return. In autumn, the colours are beautiful, and the fishing is often at its best. These periods also tend to be less busy than the peak summer months, offering a more tranquil experience.For those prioritising wildlife photography, particularly birdwatching, late spring is often the most rewarding. The delta is filled with nesting birds, and the landscape is lush. Early autumn is also great for observing migratory patterns as birds prepare for their winter journeys.If you enjoy warmer weather and don't mind more visitors, July and August offer the hottest temperatures, ideal for boat trips and enjoying the delta's waterways.
