The best time to go to Diafani is during the shoulder seasons of May, early June, September, and early October.
During these months, the weather is pleasantly warm, ideal for swimming and exploring, without the intense heat and larger crowds of mid-summer. You'll find most local businesses are open, offering a full range of services and experiences. It's a great time for couples seeking a relaxed and authentic Greek island experience.
For those who enjoy a lively option and don't mind warmer temperatures, July and August are also suitable. This is peak season, with all establishments operating at full capacity and more events taking place.
