The highest concentration of midges in Scotland is overwhelmingly found in the West Highlands and the Inner Hebrides. These tiny, biting insects thrive in damp, boggy, and windless conditions, making areas like Glencoe, Fort William, the Isle of Skye, and Loch Lomond notorious hotspots during the peak season from June to August. Specifically, the "Midge Forecast" often shows the highest activity in sheltered glens where the lack of wind allows them to swarm easily. Conversely, you will find far fewer midges in the more urbanized East (such as Edinburgh or St Andrews), on exposed coastal cliffs where the sea breeze is strong, or at very high altitudes where the air is too thin and windy for them to navigate. Travelers are often advised to visit the West in the "shoulder" months of May or September to avoid the worst of the swarms.
