The village of Altnaharra’s northerly latitude and inland location mean that in winter it regularly features in the daily weather extremes for the United Kingdom. On 30 December 1995, the lowest temperature UK Weather Record was recorded there, at -27.2°C. This matched a similar recording at Braemar in the Grampians on 11 February 1895 and on 10 January 1982. On 20 March 2009, it was recorded as the warmest place in the UK, at 18.5°C, the station’s warmest recorded March temperature, and possibly the first time the station had recorded the warmest UK temperature. On the same day, it also recorded the second coldest overnight temperature in the UK, at -3°C. On 8 January 2010, the temperature dipped to -22.3°C, the coldest temperature recorded in the UK since 1995.
