Argyll Midges in April — Risk, Peak Times, Kit
Effectively no midges. Plan freely. Mainland west-coast pressure with the same Atlantic humidity as Lochaber. Kintyre, Cowal, Knapdale and the islands (Mull, Jura, Islay, Arran) all carry the burden — sheltered woodland and lochside camps are the worst.
Current risk
Argyll in April: None. Effectively no midges. Plan freely.
When they bite
Out of season — no significant biting activity in Argyll this month. First proper warmth on the coast and at the sea-loch heads. Ground still cool inland; midge emergence still below threshold. Long daylight (14 hours by month-end).
What to wear
No specific kit needed for midges in Argyll this month. Build the kit list around weather, daylight and route choice.
Tactical notes
April is the last reliably midge-free month in Argyll. The big sea lochs warm up first — the heads of Loch Etive, Loch Awe and Loch Fyne see afternoon highs into the mid-teens by late April — but no part of the region is yet warm enough at ground level to trigger the midge emergence that defines May onwards.
This is one of the best months of the year for the sheltered Argyll glen walks that become brutal in July. [Glen Etive](/glens/glen-etive) at the west-end campervan zone, the head of Loch Etive at Kinlochetive, the Glen Orchy road — all clean. [Glen Croe](/glens/glen-croe) (the Rest and be Thankful road) and [Glen Falloch](/glens/glen-falloch) (the West Highland Way northbound approach) are similarly benign. The [Argyll Forest Park](/hillwalking/corbetts/ben-donich) routes — Ben Donich, The Brack, Cnoc Coinnich — give clean day-Corbetts from Arrochar.
The islands open up properly. The Arran cluster ([Goat Fell](/hillwalking/corbetts/goat-fell), [Cir Mhor](/hillwalking/corbetts/cir-mhor), [Caisteal Abhail](/hillwalking/corbetts/caisteal-abhail), [Beinn Tarsuinn](/hillwalking/corbetts/beinn-tarsuinn)) is at its best of the year for a long granite-ridge weekend: the [A'Chir ridge between Cir Mhor and Beinn Tarsuinn](/hillwalking/corbetts/cir-mhor) is technical scrambling in spring conditions, classic. Jura's [Beinn an Oir](/hillwalking/corbetts/beinn-an-oir) and the [Glenbatrick bothy](/bothies/glenbatrick) walk-in are at their best. Mull's Ben More and [Dun da Ghaoithe](/hillwalking/corbetts/dun-da-ghaoithe), with [Tomsleibhe bothy](/bothies/tomsleibhe) as base, give a quiet pre-season Mull weekend. Head net stays in the gear cupboard until at least May.
