Outdoor Scotland in May: Long Days, Low Midges
May delivers the longest spring days, excellent walking conditions, and the first midge warnings. The best month for ambitious routes before the summer crowds arrive.

Weather & conditions
Often Scotland's driest month. Long days with dawn before 5:30am and dusk after 9:30pm. Snow is largely gone except on the highest north-facing corries in the Cairngorms. Temperatures are comfortable for all activities. East coast often sunnier than west.
Midges appear in late May on sheltered west coast glens. Exposed ridges and east coast are still clear. Carry a head net as insurance.
Our take on May
May is the sweet spot. The days are absurdly long — you can leave Glasgow at 5am and still have 16 hours of walking light. The midges have not yet arrived in force. The crowds have not yet materialised. The snow is gone. If you are planning a big route — the Cuillin Ridge, a Fisherfield round, the Cape Wrath Trail — May is your month.
Best activities
- Multi-day Munro trips — 16+ hours of daylight
- Long-distance walking — peak conditions
- Sea kayaking — calm seas, long days
- Wild camping — warm evenings, minimal midges
- Bikepacking
Hillwalking
Peak hillwalking conditions. 16 hours of daylight allows routes that are impossible in winter — Cuillin Ridge traverses, multi-Munro days, through-routes. Snow is negligible except on the Cairngorms plateau. The hills are quiet midweek. Weekends see the first busy days on popular Munros.
Mountain biking
Excellent conditions. Trails are dry, days are long, and the air is warm. Bikepacking season opens — the Highlands are perfect for multi-day off-road touring. TweedLove festival preparations begin in the Borders.
Wild camping
The best wild camping of the year alongside September. Warm evenings, 16 hours of daylight, and midges only just appearing. High camps above 600m are midge-free. The midnight glow on the northwest coast is unforgettable.
Sea kayaking
Excellent paddling. Sea temperatures 10–11°C and rising. Long days support multi-day expeditions. The Argyll Sea Kayak Trail is in prime condition. Seabird colonies are nesting.
