Comments on March 2014
Unlike the very cold March of 2013, this March was well above average, equal 20th warmest since 1850. The number of ground frosts was the lowest for March since 2007. It was a dry March, the equal 56th lowest total in 165 years of record at Durham. Even so, the 12-month total remained well above average. It was a reasonably sunny month too, but still well short of the 1894 record of 191 hours.
