In East Lothian, July awakens the coastal slopes around North Berwick, calling swimmers to a daring dip by the Bass Rock—a steep volcanic plug rising sharply from the Firth of Forth. This is no casual swim but an encounter with a fiercely alive marine world where currents push and pull, demanding respect and preparation.

The approach begins from North Berwick village, with an accessible path running around 3 miles (5 km) out and back, climbing roughly 150 feet (45 meters) in elevation. The trail unspools along grassy cliffs, edged by gorse and heather, offering clear views of the iconic Bass Rock and its teeming colony of gannets. Underfoot, the terrain shifts from packed gravel to patches of rough grass, requiring steady footing especially near the craggy shoreline where the swim kicks off.

By mid-morning, the sun warms the stones, and the winds often soften—a window when the water’s surface becomes inviting yet brisk. Swimmers should be prepared for water temperatures hovering around 14–16°C (57–61°F), where wetsuits become essential armor against the chill and lively currents.

The swim itself ranges between 400 to 600 meters depending on your chosen launch point and route around the rock. The sea here is alive, with waves teasing and cold currents pressing forward, not to be underestimated. This is a swim for those comfortable in open water, with a practiced eye on tides and weather updates.

Back on land, the trail invites you to linger—take in the cries of seabirds overhead and the sharp scent of salt and wildflowers. North Berwick’s harbor is only a few steps away to warm up over hot drinks and to assess the day's adventure.

Practical preparation is paramount: start with sturdy, non-slip footwear for the approach hike, and bring layers for post-swim warmth and windbreak. Hydrate early and plan your timing to avoid the higher afternoon winds. Carry a waterproof bag for your swim gear and always check tide tables and local forecasts before heading out. Consider safety backup: a swim buddy or local guide familiar with these waters can make all the difference.

The Bass Rock Swim in July is a test of grit mixed with awe—a direct conversation with a coastal landscape still fiercely itself, challenging and rewarding in equal measure. Whether you’re ticking off an open water goal or simply soaking in East Lothian’s wild side, this journey demands respect, readiness, and a taste for adventure.
