The Met Office began the month with forecasts of a really cold June and ended the month talking about heatwaves. This meant June ended up being unremarkable on average.
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 June 2019?
Last month, I introduced chart H which shows a Weather Abnormality index (click for the details of how this is calculated). 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 June 2019 was not abnormal in any meaningful fashion. It was wetter than normal as can be seen in charts D & F above but temperatures and sunshine were typical overall.
