Perthshire Midges in January — Risk, Peak Times, Kit
Effectively no midges. Plan freely. A buffer zone between worst (west) and best (south-east). Big Perthshire — Atholl, Rannoch, Tay forest — has plenty of midges but the open glens and farmland of Strathmore and the Ochils stay manageable.
Current risk

Tactical notes
January in Perthshire is the off-season for midges and a strong month for east-side Highland walking. The region's structural advantage is on display: drier than the west coast, cooler than the south, with the rain shadow of the Lawers and Atholl ranges keeping the air noticeably less humid than Argyll or Lochaber at the same latitude. The midge population is fully dormant; no biting insect activity anywhere from Crieff to Loch Rannoch.
The Lawers range above Loch Tay is in proper winter conditions. [Ben Lawers](/hillwalking/munros/ben-lawers) at 1214m (10th-highest Munro) gives the canonical Perthshire winter day; the full ridge with [Beinn Ghlas](/hillwalking/munros/beinn-ghlas), [Meall Corranaich](/hillwalking/munros/meall-corranaich), [Meall a' Choire Leith](/hillwalking/munros/meall-a-choire-leith), [Meall Garbh](/hillwalking/munros/meall-garbh-fife-perthshire), [An Stuc](/hillwalking/munros/an-stuc) and [Meall Greigh](/hillwalking/munros/meall-greigh) is one of the great long winter rounds in Scotland.
[Schiehallion](/hillwalking/munros/schiehallion) — the conical 'Fairy Mountain' used by Maskelyne in 1774 for the first experimental measurement of Earth's mass — is a perfect winter Munro: short approach, easy navigation along the rocky ridge, and the summit view in winter covers half of Scotland. The Atholl Beinn a' Ghlo trio ([Carn Liath](/hillwalking/munros/beinn-a-ghlo-carn-liath), [Braigh Coire Chruinn-bhalgain](/hillwalking/munros/beinn-a-ghlo-braigh-coire-chruinn-bhalgain), [Carn nan Gabhar](/hillwalking/munros/beinn-a-ghlo-carn-nan-gabhar)) gives a long horseshoe day from Blair Atholl. South Perthshire's [Ben Chonzie](/hillwalking/munros/ben-chonzie) — the gentlest Munro in Scotland — gives a short safe winter Munro day from Crieff. Head net stays at home; pack ice axe and crampons.
