The best time to visit Cosmești is during the late spring (May to June) and early autumn (September to October) months.
During these periods, the weather is pleasantly warm and generally dry, making it ideal for exploring the natural beauty of the Teleorman region. You'll find comfortable temperatures for outdoor activities without the intense heat of mid-summer or the chill of winter. This allows for enjoyable walks through the local countryside and visits to nearby villages.
For those interested in local traditions and a quieter experience, early autumn is particularly appealing. The harvest season often brings a relaxed atmosphere, and you might catch local festivals celebrating agricultural produce.
