Repeating how hot it is during summer can make the word feel overused. Explore these 13 historical terms to vividly describe your sweltering experience all season.
1. Adurent
An intense heat wave during a drought might be described as “adurent,” a 17th-century word meaning “burning; hot and dry,” as noted by the Oxford English Dictionary.
2. and 3. Besweat and Forswat

4. Birsle
Birsle is a Scottish term referring to “scorching the surface with intense heat,” as defined by the OED. A day at the beach without sunscreen could leave you thoroughly birsled.
5. Calefy
Derived from the Latin verb calēre, meaning “to be hot,” calefy translates to “to heat.” A sauna session can calefy you into a dripping, sweaty state.
6. Fire-Fanged

7. Fracedo
The fracedo—or “decaying heat”—of August can cause roadkill to emit a foul odor almost instantly.
8. Madid
The oppressive humidity of a Southern summer could aptly be called “madid.” This term, meaning “wet” or “damp,” isn’t limited to weather. In his 1844 novel Coningsby, Benjamin Disraeli portrayed a character’s “large deep blue eye” as “madid yet piercing.”
9. Mastiff Day

But what’s even more sweltering than a dog day? English writer Horace Walpole coined the term mastiff day for such extremes.
“Last week, we experienced two or three mastiff days; they were far more intense than the usual dog days,” he mentioned in a 1781 letter. Despite the clever phrase not gaining traction, there’s nothing stopping you from introducing it to your circle.
10. Mooth
When the humidity is so oppressive that even moving from the couch feels impossible, you’re mooth—a Scottish term, possibly of Scandinavian origin, meaning “drained by heat.” Mooth (and moothy) can also describe the muggy weather itself.
11. Muck Sweat

12. and 13. Sweltry and Swoly
While sweltering is the modern term for unbearable heat, you can borrow from 16th-century vocabulary and opt for sweltry or swoly instead.
