For a trip to Papa Stour, the best time to go is during the summer months, specifically from June to August.During this period, the weather is at its most favorable, offering longer daylight hours and milder temperatures, which are ideal for exploring the island's natural beauty. This is when you'll have the best chance for clear skies, making boat trips to the sea caves and coastal walks more enjoyable.Nature enthusiasts, particularly those interested in birdwatching, will find late spring and early summer (May to July) especially rewarding. This is nesting season for many seabirds, and the cliffs teem with activity, providing excellent viewing opportunities for puffins, gannets, and other species.
