For most visitors, the best time to go to Delabole is during the summer months, from June to August, when the weather is at its warmest and driest.During this period, you can expect average temperatures around 18-20°C, making it ideal for exploring the Cornish coast and countryside. The longer daylight hours also mean more time for activities like visiting the Delabole Slate Quarry or walking along the nearby South West Coast Path.Couples looking for a relaxing escape will find the summer great for enjoying the local beaches such as Trebarwith Strand or Polzeath, which are less than a 20-minute drive away. Many local pubs and restaurants also extend their opening hours, offering more dining options in the evenings.Families travelling with children will particularly appreciate the summer. The milder weather is great for outdoor adventures, and many local attractions, like the nearby Tintagel Castle, have special events or longer operating hours during the school holidays.
