You'll find many local events and festivals taking place, including the Winobranie (Grape Harvest Festival) in early September, which is a significant highlight for the city, celebrating its viticultural traditions.For those who appreciate mild weather and fewer crowds, late spring (May) and early autumn (September) also offer a lovely experience. The temperatures are still agreeable, usually between 15°C and 20°C, and the natural scenery around the city, particularly the vineyards, is at its most picturesque.
