Cairngorms Midges in February — Risk, Peak Times, Kit
Effectively no midges. Plan freely. Subarctic plateau and dry continental climate keep the high tops nearly midge-free even in peak season. The wooded glens and Spey valley are a different story — sheltered, damp, and as bad as anywhere east of the watershed.
Current risk
Cairngorms in February: None. Effectively no midges. Plan freely.
When they bite
Out of season — no significant biting activity in Cairngorms this month. Often the coldest month of the Cairngorms calendar. Hard frosts, snow lie down to valley level on cold spells, and average temperatures still below the midge activity threshold.
What to wear
No specific kit needed for midges in Cairngorms this month. Build the kit list around weather, daylight and route choice.
Tactical notes
February is a continuation of the January story. The Cairngorms are routinely the coldest large area in mainland Britain, and February is statistically the coldest month — average highs around 3-4°C in Aviemore and well below freezing on the high tops. The midge population is still in winter dormancy and won't begin emerging until ground temperatures rise consistently above about 6°C, which is a late-April / early-May event in this region.
For planning purposes: a Cairngorms trip in February has zero midge consideration. [Glen Feshie](/glens/glen-feshie), Glen Derry, the Lairig Ghru, the Loch Avon basin, the Northern Corries — all entirely midge-free. The summit plateau, the [Cairn Gorm](/hillwalking/munros/cairn-gorm) ski area and the bothies are all useable without any insect-related kit.
The weather priorities in February are wind, cornice avalanche, white-out navigation and the short daylight window. If you're heading into the Cairngorm Mountain estate, the Coire Cas and Coire an t-Sneachda routes need full winter kit but no midge thinking. The same is true of every wild camp pitch in the region this month — head nets stay home.
