When to walk the West Highland Way (Milngavie to Fort William)

On the West Highland Way (Milngavie to Fort William), the most reliable start window is late May to early September. In this stretch you get long daylight, milder temperatures, open services, and snow-free high points—still changeable, still showery, but generally kinder underfoot and easier to plan around.

Outside that window you can have great days, but expect cooler, wetter, and darker conditions, with some closures and the chance of wintry spells on higher sections.

Late May to early September — the sweet spot

• Late May–June: Bright, green, and lively. Plenty of daylight, frequent dry interludes between showers. Midges begin—bring repellent and a head net for calm evenings.
• July–August: Warmest and busiest. Rapid swings from sunshine to downpours; paths can turn slick, especially around Loch Lomond. Midges peak on still days. Book beds ahead.
• Early September: A quieter feel and cooler nights that help with midges. Expect the usual mix of sunny breaks and passing showers, with daylight still generous.

What to pack: trustworthy waterproofs, quick‑dry layers, a midge plan, and footwear that grips on wet rock and roots.

April to mid‑May — spring shoulder

Quieter trails and usually fewer midges, but the weather can still bite: cold mornings, lively showers, and the odd wintry snap on higher ground. Daylight is improving though not summer‑long. Some smaller services may be limited.

Mid‑September to October — autumn shoulder

Lovely colors and less crowding. Conditions swing between crisp, bright days and blustery, wet spells; streams can rise quickly after rain. Evenings shorten fast—plan stages with the light and carry warm layers.

November to March — winter conditions

Short days, frequent rain, and periodic snow or ice on exposed sections like Rannoch Moor and the Devil’s Staircase. Many services close or run reduced hours. You’ll need experience, extra kit (warm layers, lights, microspikes if icy), and flexible plans. For most walkers, it’s worth waiting for spring.

A quick note on Highlands realities

Weather turns quickly year‑round. Even in summer, pack for rain and wind. Take care on greasy stone and roots after showers, and check for ticks after bracken or long grass.
