Midges in Fort William: when they're bad, when they're not, and how to deal with them

Fort William gets proper west coast midge pressure. It is a base for Ben Nevis, the West Highland Way and Great Glen trips, but it is also damp, sheltered in places and surrounded by water, woodland and lower slopes where midges can gather fast. If the Fort William midge forecast is bad and the air is still, expect it to be bad on the ground.

Planning baseline

Expect nuisance in sheltered spots, especially toward dusk.

When are midges worst in Fort William?

The main season usually runs from late May through September, with June, July and August the months that need the most planning. September can still bite if conditions stay mild and damp. Early spring and later autumn are usually easier.

Dawn and dusk are the worst windows. That matters because visitors are often setting off early for Ben Nevis, finishing walks late, camping, or standing around lochside stops on Loch Linnhe.

Terrain and microclimate note

The lower Ben Nevis path can be especially annoying in still, humid air before you gain height and wind exposure. Great Glen campsites and lochside stops can be the same.

If you are moving quickly on open ground, you may be fine. If you are changing boots, waiting at a campsite, sorting bags beside the car or cooking near trees and water, the midges get their chance.

Best times to visit Fort William to avoid midges

Month / period	Often better	Often worse	Terrain note
Late May	Late morning and early afternoon in open areas	Still evenings near damp ground or lochside stops	Gateway travel may feel fine while calmer base locations feel noticeably worse.
June	Breezier daytime periods and higher movement on open ground	Dusk, still evening periods and Great Glen campsites	Town-edge shelter and wooded approaches can hold midge pressure even when transit feels comfortable.
July	Open, brighter daytime windows	Humid evenings and sheltered stopovers	Local stop choice matters more than visitors often expect.
August to September	Fresher periods after wind or rain clears through	Settled evenings after warm damp days	Residual dampness and shelter can keep nuisance elevated later in the season.

Best overall windows

Breezy days, open viewpoints, higher ground, wind-exposed sections and the middle of the day are usually easier.

Worst overall windows

Calm evenings near Loch Linnhe, wooded campsites, Great Glen stops and the lower Ben Nevis path are the usual problem windows.

Calmer experience tip

For Ben Nevis midges, the worst part is often not the summit; it is the lower, slower, sheltered start and finish.

Camping note

Campers and walkers feel midges more because they are still for longer. Keep a head net in the bag if you are stopping overnight.

What to bring

For Fort William, do not rely on one trick. Repellent helps, but clothing, timing and wind exposure matter too.

Start with Smidge That Midge. It is the straightforward dedicated option for most visitors and a sensible first buy for Scottish midges.

Avon Skin So Soft Dry Oil Spray is the reputation pick. Some people swear by it, but it is not a dedicated repellent and reliability varies. Fine if you already use it; less convincing as your only protection in still, damp conditions.

Pack a midge head net if you are camping, photographing at dusk, fishing, or walking in still conditions. A head net looks ridiculous until it saves your walk.

A lightweight waterproof jacket handles showers and doubles as skin cover when the midges start working your arms and neck.

If you are choosing between repellents, read which midge repellent works best before buying.
