UK Weather Tracker #20 – September 2018

October 3, 2018 By Nigel Marriott

I thought August was unremarkable but September was even more boring!

The meteorological year starts in December which is why December appears as the 1st data point in the charts below.  More information on the layout of the charts can be found in this post.  Points lying between the upper and lower deciles are shown as open black circles, points lying between the deciles and minimum/maximum are shown as solid black circles and any month with a new record is shown as solid black squares.

I can honestly think of nothing meaningful to say about September so I won’t say anything!

I will however introduce this new chart G which is for the Temperature Range.  The Met Office tracks daily highs and daily lows for temperature and from that, they calculate the average high temperature and the average low temperature for each month.  By taking the difference between these two numbers I get this chart.

This adds some interesting context to our hot summer this year.  The high temperatures on average were also accompanied by large variations between day and night.  This is something I noticed myself in that whilst it was very hot during the day, the nights were not as uncomfortable as other years and that was because the minimum temperatures whilst high were not exceptional.
