For those people who listen to the UK shipping forecast, Colonsay is in sea area Malin, quite close to the border with sea area Hebrides. The British Meteorological Office maintains a website which provides the latest inshore forecast (scroll down to find forecast for "Mull of Kintyre to Ardnamurchan Point").


Colonsay's Climate

Colonsay's own local weather patterns provide it with a "mini-climate" that is in most respects a favourable one. Being relatively low lying (with no hills over 500 feet high), Colonsay rainfall figures are well below those on the West Coast of mainland Scotland - and like nearby Tiree, which is often quoted as the sunniest place in Britain by the weathermen, Colonsay receives above average sunshine figures in the long summer days.  Because the island is small there will usually by a soft sea or land breeze (other than for a brief spell around 7 am and 7 pm) which is just enough to ensure that midges cannot become a pest.


The presence of the sea also ensures that Colonsay never gets very cold in the winter, with frost and snow a rarity. Colonsay can experience severe gales. These are most likely in late October and November and again in February and March. A few times each year these can be disruptive to life on Colonsay when the ferry fails to make the crossing. In the middle of winter Colonsay quite often enjoys very still and clear (albeit short) days. At these times the views to the other islands can be breathtaking.
