Record Warm December in Stornoway

With one day of the month yet remaining, December 2016 looks like being a record-breaking mild month in Stornoway.

Eddy reports that the average air temperature for this December will clock in at approximately +7.7°C, almost a full 3°C above normal – or about half a degree warmer than the long-term average temperature for April!

Such a degree of warmth is ‘highly unusual’, and follows very high global air temperatures during both 2015 and 2016. This December will also rank as the warmest of any winter month (December, January or February) for the full period of the Met Office archives, which stretch back over 150 years in Stornoway (one of the longest such series in Scotland).

The following chart places the warmth within the long-term context of all winter months from 1873-2016:


The weather is set to change over the weekend, however, as a short cold snap ushers in wintry flurries and chilly north wind for the New Year.
