Hotumn (hot + autumn)

“Hotumn” (hot + autumn) is any unseasonably hot period in the fall season. “It’s Hotumn” was printed in the Daily Record (Glasgow, Scotland) on November 6, 2003.
     
”‘Hotumn’ Takes Hold as October Temperatures Soar” was published in the New York (NY) Times on October 24, 2017.
 
“Sweatember” (sweat + September) is a related term.

IT’S HOTUMN
November’s here and the weather’s gone balmy again
SCOTS sweltered in an autumn heatwave yesterday and sheltered from howling gales.

A BARE tum in autumn? That’s right, blonde student Holly Kishere, 18, soaks up some surprising sunshine on Bournemouth beach yesterday.

Sunbathing alongside the fallen leaves. Now that’s what we call an Indian Summer!

Perhaps we should call it “#hotumn” instead of #autumn around #California’s #CentralCoast…highs in the 80s & 90s! http://www.keyt.com/weather/forecast …

‘Hotumn’ Takes Hold as October Temperatures Soar
By REGGIE UGWU OCT. 24, 2017
(...)
Temperatures have scraped the high 70s across much of the United States this month, including in the Great Plains and Great Lakes regions and up and down the East Coast. In New York City on Saturday, the high was 78 degrees.
 
It’s enough to make one, or at least one’s editors, wonder whether Vivaldi needs to write a new concerto.
 
Maybe we do need a fifth season. Not autumn, but “hotumn” — a between-time when thighs and shoulders linger a little longer, and fans of fall fashion are left sweating in their boots.

How Will “Hotumn” Affect Cuffing Season?

A report in The New York Times on Tuesday designated the unseasonably warm weather we’re experiencing in much of the United States as “hotumn.” Across the country, a heat wave that has refused to let up has also refused to let us transition into the familiar behaviors and rituals of fall.
