When to Ride Scotland: Reading the Highland Weather Window

The first thing to understand about the Highland season is that there is no dry part of it. Riders arrive looking for the good month, the way you might in Tuscany or the Algarve, and the honest answer is that Scotland does not work like that. What it has instead is a set of trade-offs that shift across the summer, and a rider who understands them can pick a week that suits how they actually like to ride.

The Highlands Scotland Gravel week is a full traverse — Fort William on the Atlantic to Montrose on the North Sea, 520 to 540 kilometres over five stages, almost entirely on unpaved roads, forestry tracks and old droving routes. On that kind of ground, in that kind of country, weather is not a footnote to the route. It is a component of it.

The four variables

Forget months for a moment. Four things move across the season, and they do not move together.

Daylight. Enormous in June and July — light before four in the morning, dusk after ten at night. By late September you have lost several hours at both ends. This matters less than it sounds on a supported tour, because stages are built to be ridden inside a normal day, but it changes the feel of the evenings and the margin you have if a stage goes long.

Midges. A genuine Highland institution, active from roughly June through August. They need still, damp air, and they are at their worst at dawn and dusk. Which means they are a hotel-and-beer-garden problem far more than a riding problem — moving air keeps them off you almost entirely. By mid-September they have largely gone.

Wind. The one that actually decides your stage. On the exposed moorland sections, particularly the military-road day between Fort Augustus and Kingussie, wind changes a 70-kilometre stage more than 200 metres of extra climbing would. It is not strongly seasonal. It is simply always a possibility.

Ground conditions. Estate tracks hold water. After a wet spell the softer sections get genuinely soft, and the drainage on the older military roads — which still works, three centuries on — becomes something you notice and appreciate. Late summer and early autumn tend to give you the driest running of the year.

Summer, honestly

Late June through early August is the peak window, and it earns that on daylight and warmth. Long evenings, the best odds of a properly warm day, and the Highlands at their greenest.

What you accept in exchange: midges at the hotel end of the day, more people on the popular sections, and — counter-intuitively — no real reduction in rain risk. A July stage can be as wet as a September one. The summer advantage is temperature and light, not dryness.

Our 2026 July departure is sold out. For 2027 we run 26 June to 3 July and 28 July to 4 August.

Autumn, and why we keep the September date

The 13–20 September 2026 departure exists because September is, for a lot of experienced riders, the better week.

The midges have faded. The tracks have generally dried from their worst. The summer traffic on the well-known sections has gone. And the light does something that is hard to convey and difficult to forget — it comes in low and sideways across the moorland for most of the day rather than dropping straight down, and Glen Builg on a clear September afternoon is one of the reasons people book this route twice.

The costs are real and worth stating. Days are shorter. Temperatures are lower, particularly at Tomintoul, which is Scotland’s highest village and feels like it in the evening. And the chance of a full-day soaking is at least as high as in summer, arguably higher.

If your instinct on reading that is the light is worth it, you want September. If your instinct is I would rather be warm, take a summer date. Neither answer is wrong, and we would rather you picked deliberately than by which week was easiest to book.

Packing for four seasons in a day

This is not a figure of speech in the Highlands, and the packing list barely changes between July and September.

• A proper waterproof. Not a shower shell. Something that will still be working in hour three.
• Warm layers and gloves, in every month. Yes, including July.
• A spare pair of gloves, because wet gloves stay wet.
• Tubeless tyres, 38 mm minimum and wider is better, for wet estate tracks and rough stone.
• Something dry for the evening, and comfortable walking shoes.
• Something smart-casual for the dinners.

Towels and toiletries are provided at the hotels. Our general packing guide covers the rest, and the broader question of when to take a gravel tour compares Scotland against the rest of our programme.

How the week absorbs bad weather

The route does not change with the forecast, but the day can, and the structure is built to handle it.

Both route options run every day and you choose at breakfast — Adventure or Explorer — which means a foul morning has an obvious lighter answer that costs you nothing. The daily evening briefing covers the next day’s exposure specifically, with maps and elevation profiles. The support vehicle is on the route on every stage. And the rest day sits at Tomintoul after the two hardest days, with a distillery, an optional lighter loop and dinner included, so a hard weather week has a genuine reset in the middle of it.

The one thing we would ask: on an exposed stage, tell a guide if you are struggling rather than pressing on quietly. Wind and wet take more out of people than gradient does, and they take it out gradually enough that riders often do not notice until they are a long way into it.

Getting there, either season

Fly to Edinburgh. A shared bus transfer leaves the airport at 16:00 on arrival day for the three-hour drive north to Fort William, and it is included in both directions. On the final morning the bus leaves Montrose at 09:00 and reaches Edinburgh by about 11:00, so book return flights no earlier than 13:00.

Seven nights in small Highland hotels and guesthouses, seven breakfasts and three dinners, luggage transfer on every stage, a support vehicle with spares and a spare bike, English-speaking guides at a maximum of ten per guide, GPS routes for Garmin, Wahoo and Komoot, mechanic help with parts at cost, a closing dinner at the North Sea, a Gravel-Adventure jersey, a shared photo album and lifetime RIDERS-network membership. Flights and lunches are yours. The mechanics are on how it works.

So which week

If you want light and warmth and do not mind the midges, take a summer date. If you want the low autumn light, empty tracks and no midges, and you will pack properly for rain either way, take September.

What you should not do is pick on the assumption that one of them is the dry one. Our own view, after riding this crossing in both, is that September gives you the Highlands closest to how they actually are — which on a route that goes coast to coast across the emptiest country in Britain is the entire reason to come.

The remaining 2026 date is 13–20 September. It is the one that tends to go first.
