The West Coast of Scotland is notoriously the worst area for midges, particularly the Highlands and the Inner Hebrides. These tiny biting insects thrive in the damp, boggy, and wind-sheltered environments that characterize the western glens and islands. Hotspots like Glencoe, Fort William, and the Isle of Skye are famous for "midge clouds" during the peak months of July and August. The midges are most active at dawn and dusk or on overcast, still days when there is no breeze to blow them away. In contrast, the East Coast (including cities like Edinburgh, St Andrews, and Aberdeen) is significantly less affected because it is generally drier and experiences more consistent winds from the North Sea, which the midges cannot fly against. If you are planning a West Coast road trip during the summer, it is highly recommended to carry "Smidge" repellent, wear head nets in rural areas, and try to stay in breezy, coastal spots rather than deep, wooded glens where the Highland midge reigns supreme.
