I intend to go camping in Scotland (mainly the Isle of Mull, that is Western, central Scotland) next week, i.e. last week of May. I have read quite a lot about the weather and know I should prepare for wetness, unexpected changes in cloudiness, midges, possible wind, and 2 to 15 °C temperatures at day. However, I could not find much information regarding the sleeping part of wild camping.
What kind of temperatures should I prepare for at night, and what kind of gear (sleeping bag grade) does it mean taking?
Considering the wind and rain, may I take a standard tent, or are the winds really strong at night? Is there any specific advice beyond securing all pegs and stretching strings far away?
