The UK set a new record for maximum temperature of 38.7 degrees in Cambridge on 29th July. Other than that, the UK weather was unremarkable for the month overall, other than being warmer than normal. This goes to show that whilst individual days can be remarkable, it is rare that this is sustained.
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.
As I explained in October 2018, the addition of a Temperature Range chart (B) means I update 7 charts every month so I rotate which 6 appear in the deck above and plot the 7th as a separate chart here. Since it is summer, Frost (chart G) is shown since that is of least interest in the summer months.
How Abnormal was July 2019?
Chart H displays my UK Weather Abnormality Index (Scroll down my May 2019 post for details). The closer to zero this index is, the less abnormal and thus more “average” a month is. The higher it is, the more abnormal the month is. When the index is over 100%, we can describe the month as unusual in some way.
It is clear that July 2019 was not abnormal in any meaningful fashion. It was warmer than normal with more intense rainfall as can be seen in charts A & F above but rainfall and sunshine were typical overall.
