The best time to visit the Scottish Highlands is May to June or September. May avoids the worst of the midge season, delivers long days, and the landscape is at its greenest. September has autumn colours, lower visitor numbers, and the midges beginning to retreat. Summer is fine but the midges and the peak tourist pressure on the NC500 route make it the most demanding window.

Month-by-Month Breakdown

  • January to February: Cold, often wet, and the days are very short. The mountains can be stunning under snow. Accessibility is limited on some single-track roads in bad weather. A specialist winter landscape visit, not a general touring window.
  • March to April: Conditions improve. Days lengthen significantly. Easter can bring early visitors to the most popular areas. Midges have not yet arrived. Decent conditions for those who do not mind cooler temperatures (around 8-12C).
  • May: One of the best months. Midges are present but manageable. Temperatures around 13-16C, long days (light until 10pm or later in the north), and the landscape is vivid. Less crowded than July or August.
  • June: The longest days. The Highlands in late June can have light at midnight in northern areas. Warm by Highland standards (15-18C on good days). Midges peak in calm, humid weather, particularly in the west. Keep moving and pack repellent.
  • July to August: Peak tourist season. The North Coast 500 route is at maximum vehicle numbers. Popular viewpoints (Glencoe, Eilean Donan Castle, Loch Ness) are crowded on good days. The landscape is magnificent but the midges and the traffic make planning more complex.
  • September: Excellent. The heather has bloomed, autumn colours begin to arrive in the birch and rowan trees, midges retreat, and visitor numbers drop sharply. A very strong choice.
  • October: Dramatic autumn landscapes but shorter days and increasing rain. Accessible to those prepared for variable conditions.
  • November to December: Quiet and often atmospheric. Dark and cold but with clear skies offering the best chance of seeing the Northern Lights from northern areas.

Peak Season

July and August bring the heaviest tourist traffic, particularly on the North Coast 500. Accommodation in Ullapool, Tongue, and Durness books out months ahead in summer. Some coastal sections of the route have limited passing places and high campervan traffic in peak season.

Shoulder Season

May and September are the most rewarding windows for a general Highlands visit. May is particularly good: long days, reasonable weather, and the landscape before the midge peak. September adds the bonus of autumn colour and post-summer peace.

What to Avoid

July and August on the NC500 without accommodation booked well ahead. The route has limited accommodation in many sections and improvising in peak summer is genuinely difficult. Also, calm windless evenings near lochs and boggy ground without midge repellent.
