For most travellers, the best time to visit Olbia is during the shoulder seasons of May, early June, or September.During these months, the weather is pleasantly warm, ideal for exploring the beaches and archaeological sites, but without the intense heat and larger crowds of July and August. You'll find that many of the shops, restaurants, and attractions are fully open, offering a complete experience without the peak season bustle. It's a great time for couples looking for a relaxed yet engaging holiday, as well as families who prefer a slightly less crowded environment for sightseeing and beach days.If you're particularly keen on watersports or simply want the hottest weather for sunbathing, July and August offer the warmest temperatures and liveliest atmosphere. However, be prepared for more visitors and higher prices during this peak summer period. While lively, these months can be very busy, which might not suit those seeking a more tranquil escape.
