Skye & the Small Isles Midges in August — Risk, Peak Times, Kit
Hard going at dawn and dusk. Head net essential outdoors. Skye sees its share — the Cuillin glens are sheltered enough to hold midges, and low-level coastal walks pass through hostile patches at dawn. Rum, Eigg, and Muck range from mild (windy headlands) to severe (sheltered shores).
Current risk
Skye & the Small Isles in August: High. Hard going at dawn and dusk. Head net essential outdoors.
When they bite
Peak biting windows are dawn 5–8am and dusk 7–10pm. Continuing peak. Often the wettest month with high after-rain humidity. Daylight beginning to shorten (sunset around 9pm by month-end). Sea-surface temperatures at their summer maximum.
What to wear
- Smidge repellent (75ml)
- LifeSystems head net
- Light-coloured long-sleeve baselayer — midges have a strong preference for dark clothing.
Tactical notes
August on Skye is roughly indistinguishable from July from a midge perspective: same Glen Brittle problem, same Glen Sligachan problem, same Cuillin ridge respite, same Trotternish escape. The visitor numbers peak in August — the Glen Brittle SYHA fills, the Fairy Pools car park overflows, the Quiraing roadside is bumper-to-bumper at golden hour. Many of those visitors haven't read the local script. The midge-naive camper who pitches by Loch Cill Chriosd or on the foreshore at Elgol in a calm August evening will not have a happy night.
The day-mountain calculus is unchanged from July. The [Inaccessible Pinnacle](/hillwalking/munros/sgurr-dearg-inaccessible-pinnacle) is at its busiest with guided traffic — the climbing is no easier in August and the queue is no shorter. [Sgurr Alasdair](/hillwalking/munros/sgurr-alasdair), [Sgurr Mhic Choinnich](/hillwalking/munros/sgurr-mhic-choinnich), and the [Bla Bheinn](/hillwalking/munros/blabheinn-bla-bheinn) round all work on summit time, lose on descent time. The southern Cuillin Munros — [Sgurr Dubh Mor](/hillwalking/munros/sgurr-dubh-mor), [Sgurr nan Eag](/hillwalking/munros/sgurr-nan-eag) — give the best gabbro-on-sea-cliff days in Scotland and are reliably midge-free above about 600m.
Small Isles in August: harder. [Dibidil](/bothies/dibidil) on Rum's south coast is genuinely difficult in calm August weather — the bothy itself is a small stone box on a humid sheltered shoulder. [Camasunary](/bothies/camasunary) gets some Atlantic breeze and is more manageable. [Tomsleibhe](/bothies/tomsleibhe) on Mull, by Loch Spelve, is a slightly milder midge environment than equivalent Skye spots — Mull as a whole runs lower pressure than Skye. If you're choosing between Mull and Skye for an August week, the midge weather alone tilts the decision to Mull. Ben More on Mull and the inland routes from Tobermory deliver excellent island hill-walking on slightly less brutal terms.
