An historical perspective of the climate statistics for Coventry during January 2018
There has been some modest warming during January in Coventry since the Millennium, with mean monthly temperatures (4.6C) having risen by 0.3C compared to 30 year averages from the end of the 20th century (1971-2000).
So, with a mean monthly temperature of 5.2ºC, 0.9ºC above that 1971-2000 average, January 2018 can certainly be rated as a mild first month of the year in our region.
However, seven January months have been milder than this year since the Millennium (2002, 2005, 2007, 2008, 2012, 2014, and 2016, so it has by no means been an exceptionally mild January locally. Overall, it has been the mildest January in Coventry since 2016 (5.3C).
