The best time to go to Ona for pleasant weather and a full experience is during the summer months, specifically from June to August.During this period, the days are long, offering plenty of daylight to explore the island, and the temperatures are at their mildest, typically ranging from 10°C to 18°C. This makes it ideal for enjoying outdoor activities like walking to the iconic Ona Lighthouse, exploring the rocky shores, or simply relaxing and taking in the coastal views. All local businesses, including the cafe and craft shops, are fully open during these months.Couples looking for a peaceful escape will appreciate Ona in early June or late August. The weather is still favourable, but there are fewer visitors, allowing for a more intimate experience of the island's natural beauty and the opportunity to enjoy quiet moments together.For families, July is often the best choice as it typically offers the warmest weather and the longest daylight hours, superb for children to explore the beaches and enjoy the outdoor environment.
