The best time to go to South Ronaldsay is during the summer months, from June to August, when the weather is mildest and daylight hours are longest.
This period offers the most comfortable conditions for exploring the island's outdoor attractions, such as the coastal paths and ancient sites like the Tomb of the Eagles. The longer daylight hours mean you have more time to visit attractions and enjoy activities like birdwatching or scenic walks. It's also when most local events and festivals take place.
For travelers interested in wildlife, late spring (May) and early autumn (September) can also be good times to visit. During these shoulder seasons, you might see migrating birds, and the weather can still be pleasant for outdoor activities, often with fewer visitors than in peak summer.
