Summer is seriously busy on Skye, when the resident population of 10,000 can treble in size and accommodation fills up very quickly, often weeks, if not months in advance. Peak season in Scotland is between the last week in June, when the Scottish schools break up, until the first week in September, when English schools return, so, if you can it is often worth avoiding this period to avoid over-inflated accommodation prices, being turned away from full restaurants and traffic jams. The Easter holidays, always the first two weeks in April in Scotland, can be just as busy.
Okay, so I got the bad news out of the way first! Skye is a wonderful island, with friendly people, wonderful seafood and views to die for. When you factor in that the best weather on Skye usually occurs in the Spring and early Summer then I would suggest that the best time to visit the Misty Isle is from late April until late June when the days are usually long and dry and the midges haven't quite built themselves up into man eating swarms by then. Once the Summer rain - by late June the Atlantic Ocean has heated up and its warm air condenses over the Cuillin Mountains to produce sporadic, and sometimes heavy, showers over much of the island in July and August - and crowds have dispersed, Autumn can be a rewarding time to visit. September , October and early November produces beautiful colours on the landscape from the forests and ferns in the south of Skye to the heather clad moorland across the north, and the soft golden light is a photographers dream - no need to get up at the crack of dawn or stay up late to catch that perfect light.
Winter can reap rewards for the Skye bound traveller too but travel in hope rather than expectation and you won't be disappointed. Storms rolling in off the Atlantic are common but the upside is you won't have to share the island with too many other visitors. In December and January it doesn't get light until 09.00 and is dark again by 16.00 so careful itinerary planning is required to see all of the sights that you have on your list. By February and March the days are longer and there are more clear crisp Winter days with the snow capped mountains of the Cuillins and the mainland framing your views. Many visitor attractions, restaurants and accommodation providers close in the Winter months but there are still enough to keep you entertained, fed and sheltered.
