Air Vice-Marshal Grieve reports the conditions below against his will.
Dunoon
Midge risk in Dunoon right now: Extreme (10/10). Peak tonight: 8:00pm.
Cowal's coast, forestry and damp sheltered ground make Dunoon worth watching in calm weather. Season: June–August.
Extreme — The Cloud owns this ground. Dusk here is a feeding window, not an evening. If you must be out, cover everything and move fast. You will leave. You will leave sooner than planned.
“I recommend being elsewhere.”
Dunoon faces the Clyde and catches coastal air, but the Cowal peninsula behind it is thick with forestry, damp glens and sheltered lochans. The town waterfront is fine; the wooded areas toward the Ardgartan and Loch Eck side are where midges gather.
The ferry crossing from Gourock is usually the breeziest part of the trip.
“The sector reports excellent feeding conditions at dusk. Morale among the squadrons is regrettably high.”
— AIR VICE-MARSHAL GRIEVE, EVENING DISPATCH
Dunoon sits on the Cowal peninsula where the Firth of Clyde meets the Highland edge, and the town's dual geography — coastal frontage backed by dense forestry and multiple sea lochs — creates a sharp midge gradient.
The waterfront, the pier, and the town centre catch the Clyde breeze and are generally low-risk.
The problem is inland: the Cowal peninsula is thick with commercial forestry, damp glens, and sheltered lochans, all of which create ideal midge habitat within a few hundred metres of the coast.
Dunoon's season runs slightly later than the Argyll norm: the Cowal peninsula is cooler in spring, so activity starts in early June rather than late May, but mild autumns can extend into September.
The road from Dunoon toward the Ardgartan Hotel and the Loch Eck shore is the most consistently reported trap zone — the A880 runs through a forestry corridor that holds still air and damp ground, and the loch shore lay-bys are classic trap spots where visitors stop to admire the view and discover the midges.
The ferry crossing from Gourock deserves specific mention: the breeze on the water is reliable and strong, and passengers who feel no midges on the crossing often assume Dunoon will be the same.
It is not.
Practical advice: Dunoon's waterfront and the town centre are safe at any time.
Any journey inland — the A815 toward the Ardgartan, the route toward Loch Eck, or the forestry walks behind the town — needs timing.
The first mile inland from the coast is the transition zone where the breeze dies and the damp woodland air takes over.
