Worst Places for Midges in Scotland (And Where to Go Instead)

I was standing at the edge of a loch in Glencoe, congratulating myself on finally making it to one of the most dramatic landscapes in Scotland, when I noticed the cloud. Not a weather cloud. A midge cloud. Hovering at head height, moving with me, entirely unimpressed by my Smidge application from four hours earlier.

Past-me had done a lot of research before that trip. Past-me had not packed a midge net.

If you’re planning a trip to the Scottish Highlands, this is the one practical topic worth actually reading up on. Not because midges are dangerous, they’re not, but because they can genuinely ruin an otherwise brilliant day out if you’re in the wrong place at the wrong time. For a broader overview of what to expect, our complete Scotland guide covers the essentials.

Quick Answer: Where Are Midges Worst in Scotland?

The northwest Highlands and parts of Argyll and Bute are consistently the worst areas for midges in Scotland. Specific hotspots include Glen Coe, Fort William, the Great Glen, Torridon, Isle of Skye, Loch Lomond and The Trossachs National Park, Cairngorms National Park (particularly the wet woodlands), and stretches of the North Coast 500 route.

Area	Why It Is a Midge Hotspot	Best Practical Move
Argyll and Bute	Its lochs, woodland and frequently damp west-coast conditions provide classic midge habitat.	Choose exposed coastal stops and avoid still evenings beside freshwater.
Loch Lomond and The Trossachs National Park	Woodland, sheltered loch shores and humid evenings can produce intense swarms.	Plan waterside walks earlier in the day and keep an evening indoor option.
Fort William and Glencoe	Highland glens can be sheltered from wind, particularly after rain.	Keep moving on walks and avoid standing in a calm glen at dusk.
Isle of Skye	Skye has exposed coast, but inland and sheltered locations can be very midge-prone.	Use the coast and breezy viewpoints to your advantage.
Cairngorms National Park	Wet woodland areas are more troublesome than open, windy upland ground.	Check conditions before choosing a low-level woodland route.
Perthshire	Wooded countryside and lochside ground can be uncomfortable in still, damp weather.	Save relaxed outdoor meals for breezier afternoons.

The midge forecast rates areas on a scale of 1 to 5. Inland areas of the northwest Highlands regularly hit level 5. Coastal areas nearby sit around level 4. If you want to avoid them entirely, Edinburgh, the East Coast, and the Central Belt sit at level 1.

Why the West Highlands Are So Bad for Midges

It comes down to what midges need to breed: wet soil. Scotland’s west coast and highland interior have it in abundance, all that damp moss, boggy ground, and sheltered glens with minimal wind. Female midges (the ones that bite, for the record) lay eggs in wet soil, and the Western Highlands is basically a luxury midge nursery.

The species responsible is Culicoides impunctatus, the Highland midge. They’re tiny, around 1-3mm, usually grey, and they find you by detecting the carbon dioxide you’re breathing out. You cannot win by holding your breath. I’ve tried (briefly).

The conditions they love are specific: overcast, humid, mild, and completely still. A bright windy day? You’ll barely see one. A grey, damp evening in July with no breeze in a sheltered glen? That’s their moment. For what it’s worth, current conditions in Scotland are sitting at 61°F with 88% humidity and clear skies (as of March 2026), which is unusually mild for this time of year but still safely outside peak midge season.

The Worst Locations in Scotland for Midges

Here’s where the Scottish midge forecast consistently puts the highest activity:

• Northwest Highlands (inland areas rated level 5 on the forecast scale)
• Argyll and Bute (level 4-5 depending on conditions)
• Glen Coe and the surrounding area
• Fort William and the Great Glen
• Torridon
• Isle of Skye
• Loch Lomond and The Trossachs National Park
• Cairngorms National Park (especially in wet woodland areas)
• Parts of the North Coast 500 route

What all of these share: sheltered, boggy, wet highland terrain with limited wind exposure. If a place is famous for dramatic scenery and moody weather, it’s probably also famous for midges. If you’re planning a road trip through these areas, our North Coast 500 planning tips cover logistics and timing that can help you dodge the worst of it.

Midge Season: When Is It Actually Bad?

Midge season in Scotland runs from May to September, with peak activity in July and August. October through March you’re generally fine, the cold keeps them dormant. Honestly, search interest for Scotland travel has been rising over the past year with peaks in the winter months, and that’s not a bad thing if you’d rather skip the tiny vampires altogether.

Within a given day, midges are most active at dawn and dusk. Midday, especially if it’s sunny and breezy, is usually manageable. Plan your outdoor time accordingly.

Scotland Midge Calendar: January to December

Midge activity is concentrated in the warmer part of the year. The main season is commonly described as running from late spring into early autumn, with the strongest activity generally in July and August. Weather can shift the start, peak and finish.

Month	Typical Risk	What To Expect
January	Very low	Cold conditions make biting midge activity unlikely.
February	Very low	Still well outside the usual active period.
March	Very low	Generally a low-risk month for midge planning.
April	Low	Often a good time for Highland trips if avoiding midges is a priority.
May	Low to moderate	Activity can begin in warmer, damp places, particularly later in the month.
June	Moderate to high	Numbers build, with sheltered western areas worth watching.
July	High	Peak-season conditions are common, especially after rain.
August	High	Another peak month for swarms in calm, humid weather.
September	Low to moderate	Numbers usually taper as temperatures drop, though early September can still be active.
October	Low	Risk reduces substantially as autumn conditions take hold.
November	Very low	Outside the normal midge season.
December	Very low	Not a typical midge month.

Where to Go If You Want to Avoid Midges

Not everywhere in Scotland is a midge hellscape. The midge forecast consistently gives the lowest ratings (level 1) to:

• Edinburgh and the Central Belt
• Glasgow, Lanarkshire, Ayrshire
• Dumfries and Galloway, Scottish Borders
• Fife, Dundee, St Andrews, and the northeast coast
• Orkney and Shetland (windy coastal islands)

Windy coastal regions and open, exposed areas tend to be much lower risk. Midges can’t fly well in wind, so anywhere that gets a consistent sea breeze is a reasonable bet.

Higher altitude also helps. Above around 700 metres, conditions are less hospitable for them.

Dawn, Daytime and Dusk Risk

Dawn and dusk are the periods to take most seriously. Midges are especially active in the early morning and late evening, which is why an otherwise good day can turn irritating around breakfast outdoors or a post-dinner walk.

• Dawn: High risk in calm, damp and shaded places, particularly near woodland and freshwater.
• Daytime: Often lower risk when there is sunshine, a breeze or steady movement. Still, sheltered and overcast conditions can keep them active.
• Dusk: Frequently the most frustrating time for sitting outdoors, camping, barbecues and lochside stops.

Weather That Makes Midges Worse

Midges favour still, overcast, humid and damp conditions. Rain can contribute to a stronger midge experience afterwards, particularly when the air settles and temperatures remain mild. Sheltered ground beside water, boggy areas and woodland edges are the places to be most cautious.

Wind is your friend. Even a light breeze can disrupt a swarm, so exposed coastal places and open higher ground are often more comfortable than a protected glen

How to Survive Midges If You’re Going Anyway

You’ve booked Skye in August. Good luck. Here’s what actually helps:

Repellents:

• Smidge contains 20% Picaridin, which blocks the CO2 receptors midges use to find you. This is the one most Scottish outdoor types swear by.
• Avon Skin So Soft dry oil spray has a long-running anecdotal reputation as a midge deterrent. DEET-free.
• DEET-based repellents come in 25%, 50%, and 100% strengths and are effective, though they’re not environmentally friendly and can damage certain materials.
• Lotions containing bog myrtle are also used.

Clothing and gear:

• Midge head nets. Not glamorous. Extremely effective. Don’t be like me and leave yours at home.
• Long sleeves and trousers.
• Light-coloured clothing.

Behavioural adjustments:

• Stay indoors at dawn and dusk.
• Keep moving. Midges struggle to land on a moving target.
• Seek out open, breezy spots rather than sheltered hollows.
• Avoid camping near long vegetation or marshy ground.
• A small portable fan can help at a campsite.
• Campfires deter them too.

Check the forecast:
The Scottish Midge Forecast pulls data from biting midge traps and mini-weather stations across Scotland and gives a 1-5 rating by area. Check it before you head out. It’s genuinely useful.

What About Other Biting Insects?

Midges get all the press, but they’re not the only thing out to get you.

Scottish Clegs (horseflies) are larger, less numerous, and bite without you noticing until it’s too late. Worse bite than a midge, honestly.

Ticks are present in highland areas too, particularly in long grass and bracken. They’re rare carriers of Lyme disease, so carry a tick remover on any hill walk. Check yourself after. If you’re heading out on a Munro or any serious hill walk, like Ben Nevis, a tick check at the end of the day should be routine.

Midge Forecast Ratings at a Glance

Rating	Areas	What to Expect
1	Edinburgh, Central Belt, East Coast, Borders	Minimal midge activity
2	Greenock, parts of Aberdeenshire	Low but present
4	Northwest Highland coasts, Argyll and Bute	Noticeable, take precautions
5	Inland northwest Highlands	Peak midge conditions

The Honest Summary

The worst place for midges in Scotland is the northwest Highlands inland, particularly around Glen Coe, Fort William, Torridon, and the Great Glen, with the Isle of Skye and Argyll and Bute not far behind. July and August are the cruelest months. Dawn and dusk are the cruelest hours.

None of this means you shouldn’t go. These are some of the best landscapes in the country, and a midge net plus a decent repellent makes a real difference. The currency is the British pound (£), English is spoken everywhere (though Scottish English takes some tuning in to), and turns out a tube of Smidge costs about the same as a coffee. Just don’t do what I did and assume you’ll be fine without either.

Frequently Asked Questions

What month are midges worst in Scotland?

July and August are generally the worst months for midges in Scotland. Numbers often rise from late May, build through June and begin to decline during September as temperatures fall.

Are midges bad on the Isle of Skye?

Midges can be bad on Skye in sheltered, damp and calm places, especially around dawn and dusk. Exposed coastal locations with a breeze are usually much more comfortable.

Can midges bite through clothes?

Loose, light-coloured long sleeves and trousers provide useful protection, though thin or tight fabric may not stop every bite. Covering exposed skin is especially helpful during still evening conditions.

Do Scottish midges carry disease?

The Highland midge is mainly known for causing itchy, irritating bites. The nuisance comes from swarms and skin reactions, not the disease risk associated with some mosquito species elsewhere.

Is September a good time to visit Scotland to avoid midges?

September is usually a better choice than July or August, particularly later in the month. Early September can still bring active midges in warm, damp weather, so check the forecast before outdoor plans.
