An historical perspective of the climate statistics for Coventry during October 2019
In the twentieth century, there was little sign of warming in October, perhaps just a 0.3°C rise in average temperatures, though since the Millennium, there has been a 1.3°C increase on the 1990’s. The 2001 to 2018 October average was 11.5C compared to 10.2C average from 1991 to 2000.
All of our coldest Octobers were recorded before 1919, while many of the best have been in more recent years, as can be seen below, with 2001 being the warmest October in Central England's temperature series since at least 1659.
October 2019 has been a relatively cool month (10.2C), back to the levels more common at the end of the last century, making it the coolest October in Coventry since 2012 (9.6C).
Only 5 October months have been cooler than 2019 in the past 25 years (1997, 2002, 2003, 2009 and 2012).
Some may be surprised to hear that October is the wettest month of the year in Coventry (67.8mm from 1981-2010), with autumn our wettest season.
October 2019 has far exceeded that 30 year average with 95.0mm of rain, 140% of normal. It has been our wettest October since 2013 (146.4mm), with only 3 wetter since the Millennium, and 7 wetter in the past 52 years (1980, 1987, 1998, 2000, 2002, 2004 and 2013).
There were 18 ‘wet days’ in the month, the highest incidence of such days sine 1960 (20); just out of interest, 1903 hold the record with 22 ‘wet days’.
You don't need me to tell you it has been wet in Coventry over summer & autumn so far; from June to October we have recorded 480.4mm of rain (157%) making this the wettest such 5 month period since 1960. Only 1875 1880 & 1960 have been wetter since 1870.
Although there was a 59% increase in sunshine levels in Coventry between 1894 and 1999, the early 21st century (2000 to 2018 = 97.0hr) has seen a fall in sunshine totals back below the levels more common in the 1980s (103.4hr).
October 2019 has been another disappointing October month in Coventry (91.1hr) but only the dullest since 2017 (75.6hr) with 87% of average monthly sunshine.
