Islay Weather 5 Day Forecast, Current Weather and Climate

Islay has a relatively mild climate, being warmed by the waters of the gulf stream and largely sheltered from the open waters of the Atlantic. While snow and frost occur relatively rarely, gale force winds are not uncommon. Like in other parts of western Scotland, the weather can sometimes be very changeable although there are also periods of stable weather. With nothing in between Islay and the east coast of Canada, except the huge Atlantic Ocean, the south-westerly winds are an almost constant factor. Check also the current weather conditions on Islay
