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

For most walkers, starting in late May to early August gives the best conditions on the West Highland Way. You’ll get the longest days, milder temperatures, and fully open services, with snow and ice unlikely on the higher sections.

Expect Scotland’s usual mix of sunshine, showers, and brisk breezes. The main trade‑offs in this window are midges (worst on still, damp evenings) and busier paths—both manageable with a head net, repellent, and advance bookings.

Late May to early August — best overall

• Long daylight makes flexible stages and unhurried days.
• Generally the warmest stretch of the year, with plenty of dry spells mixed with showers.
• Most campsites, shops, and baggage services are in full swing.
• Midges: lighter in late May, strongest late June to August. A breeze keeps them down; still glens and forests are the worst. Bring a head net, repellent, and consider early starts.

April to mid‑May — spring shoulder

• A lovely, quieter time with fresh greens and fewer midges.
• Weather can swing quickly: bright sunshine one day, cold rain or a frost the next. Nights can still feel wintry.
• Expect some wet, muddy sections and chilly mornings; pack warm layers and full waterproofs.
• Some accommodation and facilities may only just be opening for the season.

Mid‑August to September — late‑summer into early autumn

• Still a good walking window with comfortable temperatures and heather in bloom.
• Showers are common, and days are steadily shortening.
• Midges remain active into early September but usually ease with cooler nights and breezier weather.
• Slightly less busy than peak summer, but still plan ahead for stays.

October to March — off‑season

• Short days, frequent rain, and the real chance of stormy weather, sleet, or snow on exposed sections like Rannoch Moor and the Devil’s Staircase.
• Trails can be saturated; burns may run high after heavy rain.
• Many services reduce hours or close; wild weather requires experience and winter‑ready kit.
• There are crisp, beautiful days, but you’ll need flexibility and solid foul‑weather plans.

Quick practical notes

• Expect changeable weather year‑round; always carry waterproofs and warm layers.
• Footwear that handles wet ground pays off, even in summer.
• In peak months, book beds and campsites early; in shoulders, check opening dates.
• For midges: head net, repellent, long sleeves, and pick breezy lunch spots.
