North-West Highlands Midges in March — Risk, Peak Times, Kit
Effectively no midges. Plan freely. Torridon to Assynt — heavily forested glens, low pressure on exposed coast and ridges, brutal in sheltered hollows. The combination of latitude and Atlantic humidity gives the densest swarms outside Lochaber proper.
Current risk
North-West Highlands in March: None. Effectively no midges. Plan freely.
When they bite
Out of season — no significant biting activity in North-West Highlands this month. Daytime maxima creeping up to 7-8°C on the coast, single digits inland with frequent frosts. Snow lie persisting on the Torridon ridges and in the Fisherfield corries. No adult midge activity.
What to wear
No specific kit needed for midges in North-West Highlands this month. Build the kit list around weather, daylight and route choice.
Tactical notes
March in the North-West Highlands is shoulder winter — the days are getting noticeably longer but the weather is still firmly in winter regime, especially in Assynt and the Fisherfield interior. Cape Wrath Trail attempts begin to appear in late March from south-bound walkers using the cold ground as a way to avoid both the worst of the bog season and the worst of the midge season — the calendar trade-off is real and most walkers get it wrong by starting too late.
From a midge perspective the picture is unchanged from January and February: dormant population, no flight activity, no kit required. [Glen Shiel](/glens/glen-shiel), [Glen Affric](/glens/glen-affric), [Glen Torridon](/glens/glen-torridon) and [Glen Strathfarrar](/glens/glen-strathfarrar) are all midge-free this month even at lower elevations. The west-facing sandstone of [Slioch](/hillwalking/munros/slioch) above Loch Maree gives one of the best high-mountain views in Scotland in late-winter conditions and you'll have it almost to yourself.
The practical takeaway: any North-West Highlands trip in March needs winter kit and weather-window judgement, not midge kit. The bothies — [Carnmore](/bothies/carnmore), [Bearnais](/bothies/bearnais), [Iron Lodge](/bothies/iron-lodge), [Strabeg](/bothies/strabeg) — are open and free of biting insects. If you're heading into Fisherfield this month, the long approaches through bog country are typically firmer underfoot than they will be in May and June, which is a hidden advantage. Head net stays at home; ice axe and crampons come instead.
