Holidays and busy periods

Bank holidays for Scotland come from GOV.UK, listed for the next two years in each month above. Many Britons travel on bank holiday weekends, so book transport and rooms early.

School holidays are set by each local council, so we do not list dates here. Check Scottish school term and holiday dates (mygov.scot).

From our Glasgow guide

Glasgow works all year. The large museums are indoors, and the parks, the botanic gardens and the Clyde waterfront suit dry days. Visit Glasgow keeps a festivals and events calendar; check organisers' sites for dates.

  • Spring (March to May): A good time for the Botanic Gardens, Kelvingrove Park and the waterfront walks.
  • Summer (June to August): Long days for the parks and the Clyde, and for day trips to Loch Lomond or Stirling.
  • Autumn (September to November): Museums, theatres and music venues have a full programme, and the parks change colour.
  • Winter (December to February): Short days. Kelvingrove, the Burrell Collection, the Riverside Museum and the theatres carry an itinerary indoors.

We do not publish crowd or price seasonality: none of the sources used for this page states it.

How we work this out

  • Temperatures, rainfall, rain days and sunshine are the Met Office 1991-2020 monthly averages for one weather station (Paisley). They describe a typical month, not a forecast. We never call a live weather service for this page.
  • Packing: warm coat below 10°C highs, warm jacket below 15°C, light layers below 20°C. A full waterproof when a month has 12 or more days with 1 mm of rain or at least 80 mm; a light waterproof from 9 days; sunscreen and a hat from May to September. Shoes with grip when typical nights are 3°C or colder.
  • Daylight is the astronomical day length, including the usual allowance for atmospheric refraction, on the 15th of the month at the latitude of Glasgow.
