The same record breaking high which delivered unusually cool temps to Southern Britain to end August and meteorological summer shifted position from near Iceland to Germany then delivered the warmest September day to Ireland and Scotland since 1906, since 1961 for Wales and 2016 for England.

The below pressure chart shows the set up with the UK placed NW of a low over the Bay of Biscay and high over Germany, winds blowing between these two features transported very warm, humid air WNW into Britain.

While unusually warm throughout Ireland, it was the Atlantic coastal communities which saw the highest temperatures.

Located on the Iveragh Peninsula of Co Kerry, the village of Glenbeigh recorded a temperature of 28.6C which made for the Republic of Ireland’s warmest September day since 1906.

Several sites in the SW corner of Ireland witnessed their warmest September day’s in recorded history.

In Britain, Gogerddan near Aberyswyth in Cardiganshire saw a sweltering maximum of 30.7C. This made for the highest September temperature measured in Wales since 1961.

Also, a minimum of 20.5C was recorded in Aberporth which surpasses a minimum of 18.9C at Rhyl back in 1949 as the warmest September night for Wales. Exeter, Devon also observed an unusually late ‘tropical night’ with a minimum of 20.1C.

While temps eased down over SW Britain, they climbed further north. A temperature of 28.8C was reached at Charterhall, Berwickshire making for Scotland’s warmest September day since 32.2C was reached at Gordon Castle, Moray back in 1906!
