Mattinata is best enjoyed during the shoulder seasons of May, June, September, and early October.During these months, the weather is pleasantly warm, ideal for exploring the Gargano National Park and enjoying the beaches without the intense heat and larger crowds of July and August. You'll find most local businesses are fully open, offering a complete experience of the town and its surroundings.For those who prefer a quieter holiday focused on relaxation and scenic walks, late September and early October are particularly lovely. The sea remains warm enough for swimming, and the natural beauty of the area, especially the coastal paths, truly shines with fewer visitors. This period is superb for couples seeking a peaceful escape.If your primary interest is enjoying the sea and sun, June is an excellent choice. The water is inviting, and the days are long and bright, superb for boat trips to the sea caves or simply lounging on Mattinata's pebble beaches.
