The average daily temperatures in July and August are usually in the mid-20s Celsius, great for enjoying the region's natural beauty.For those interested in cultural events and local traditions, visiting in August can be particularly rewarding. Many of the surrounding mountain villages host festivals (sagre) during this time, celebrating local food, music, and heritage. This offers a wonderful opportunity to experience the authentic Friulian culture.If you prefer cooler temperatures and fewer crowds, May, June, or September are excellent choices.
