Autumnal Indian Summer

The term Autumnal Indian Summer or Indian summer is a non-season period of unusually warm weather with dry conditions, which occur during the autumn or fall season in temperate regions of the Northern Hemisphere.

According to the Met Office, the first usage of the phrase started in the United States, where a Frenchman called John de Crevecoeur wrote a letter in 1778.

His description said the Mohawk country has rain that is followed by an interval of calm and warm weather called the "Indian summer."

Its usage in the UK came during the early 19th century and became widespread, which also depicts a warm autumn spell that was not new to Britain.

The UK weather agency said the warmest temperature recorded for the territory during the months of October and November was 29.9 degrees Celsius on the 1st of October 2011 in Gravesend, Kent.

Meanwhile, 22.4 degrees Celsius was recorded on the 1st of November in 2015 at Trawsgoed, Ceredigion.

What is an African Plume?

The so-called African plume is a hot air mass moving from Africa to the British Isles and its surrounding areas in Europe.

It is a southerly wind with warm air, according to the Ireland-based internet publication TheJournal.ie.

In recent years, the weather phenomenon had affected the UK and caused similar rise in temperatures, with many calling it as a "mini-heatwave" due to extreme hot temperatures.

In April 2018, the TheJournal.ie reported that a 1,500-mile air mass struck Ireland the UK where temperatures forecasted to have reached a maximum of 18 degrees Celsius.

During this time, the region just came from its winter season which brought a blanket of snow and freezing temperatures.

Currently, the looming hot mass of air will likely lead to the same weather conditions as it did four years ago.
