June, July and August are normally the warmest months in Scotland, with average maximum temperatures ranging from approximately 15°C (59°F) to 17°C (63 °F). Scotland’s high latitude means that you will enjoy lovely long summer days and often an extended twilight.

Rainfall in Stornoway is high, totaling 1259 mm (about 50 inches) in a typical year.  August is not the wettest month of the year, but in the past 10 years it has consistently remained the wettest summer month.

With the weather and event agenda in mind, here are some guidelines on what to bring and event-appropriate apparel:
