The influence of the Atlantic Ocean & the Gulf Stream creates a mild oceanic climate. Temperatures are generally cool, averaging 6.5°C in January & 15.4°C in July at Duntulm. Snow seldom lies at sea level & frosts are less frequent than on the mainland. Winds are a limiting factor for vegetation. South-westerlies are the most common & speeds of 80mph have been recorded. High winds are especially likely on the exposed coasts of the Trotternish & Waternish peninsulas. In common with most islands of the west coast of Scotland, rainfall is generally high at 1,500-2,000mm per annum & the elevated Cuillin are wetter still. Variations can be considerable, with the north tending to be drier than the south. Broadford, for example, averages more than 2,870mm of rain per annum. Trotternish typically has 200hrs of bright sunshine in May, the sunniest month. On 28 December 2015, the temperature reached 15°C, beating the previous December record of 12.9°C, set in 2013.
