SSEN's Weather Watch for September 2019

Summer 2019 - that is to say June to August - was warmer than the 30 year average across most of Europe. You can see this in the Prescient Weather Ltd map on our main page which shows a model estimate of the temperature departure from average, with the red shading highlighting warmer than average.

For the UK, Summer 2019 was record-breaking with a maximum temperature of 38.7 Celsius at Cambridge University Botanic Garden, logged on 25 July; the highest temperature ever recorded in the UK. 

The Met Office confirmed that Scotland was very wet overall, as it recorded its second wettest Summer (in a series from 1910), only surpassed by Summer 1985.

Looking ahead to the remainder of September, we’re expecting the weather maps to show low pressure established between Scotland and Iceland, and a high pressure anomaly to the west or southwest of Ireland. This type of weather pattern is likely to bring mostly westerly winds from the nearby Atlantic Ocean.

As a result, we’re expecting temperature levels to be mostly below average, occasionally near average, during the month. Some windy spells are highlighted, especially across the coasts of Scotland, when low pressure systems move east in the pathway between Iceland and Scotland.

Together with the strong winds, periods of heavy rain are likely, notably for north-western parts of Scotland. Rainfall levels in southern England will probably be below average overall. We’re not expecting any major departures from average in sunshine levels, with values coming in close to normal. 

The map above shows the forecast temperature anomaly for 7-11 September. The blue values illustrate colder than average, which dominate large parts of Europe. This pattern will be typical through September, although southern parts of Europe will tend to trend warmer. The warmest regions, relative to normal, are likely to be far eastern Europe including Russia.

As Autumn is truly upon us, we’ll be back in a few weeks to discuss the likely weather trends for October.
