Surfing Sandside Bay: The Complete Guide

Sandside Bay is a sandy-bottom beach break located in Caithness, UK (Scotland), offering a left-hander along the North Atlantic's seasonal swells. Sandside Bay would be famous for its quality left-hander if it weren't for its proximity to the Dounreay nuclear facility.. Rated as advanced difficulty with uncrowded conditions, this beach break is a worthy destination for surfers looking beyond the usual suspects.

Best Conditions

Swell Direction: The ideal swell direction is NW (310°), with workable conditions from W to N (280°–360°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Sandside Bay needs a minimum of 1m / 3ft to start working and handles swells up to 2.5m / 8ft before conditions deteriorate.

Swell Period: Look for a swell period of at least 9 seconds, with 13 seconds being the sweet spot. Longer periods deliver more organized, powerful waves with better shape.

Wind: True offshore here blows from the SW (225°). The full offshore range spans S to W (180°–260°). Glassy conditions under 4km/h from any direction also produce excellent surf. Plan for sessions throughout the day.

Tide: This spot works best at mid to high tide.
