Talking About Weather: Hot

Hi folks! Today I’ll be continuing my series on weather with suggestions on how to describe the heat of the day, or how hot a day is.


If you step outside and you begin to sweat and feel a bit uncomfortable, it’s probably safe to describe the day as hot. Here are some example sentences.

  • Beijing summers are so hot.

  • It’s gotta be the hottest day of the year today. (Superlative Form).

  • It’s hotter than the sun out there. (Comparative form).


This word suggests a temperature that is of a lower temperature than a day that is described as hot, but also much warmer than a day that might be described as cool (see previous blog). Usually days in the late spring or early fall or describes as warm.

  • Person 1: How’s the weather today?

  • Person 2: Warm, I’d say—not too hot, but certainly not cold.

  • It’s warmer today than it was yesterday. (Comparative form).

  • It’s not the warmest day in the world, but it’s not too bad. (Superlative from).


Hot days are often humid. Humidity, how humid the day is, refers to the amount of moisture in the air. Often times before it rains it seems like it the air is very heavy and wet—this is humidity.

  • It’s a hot and humid day—I would avoid too much activity if you can.

  • It’s so humid I can’t stop sweating.


This noun is used most often when there has been several days of extreme heat in a row. Oftentimes in America we will say:

  • We are experiencing a heatwave.

  • I’ve had about enough of this heatwave.

  • It’s a heatwave out there.


This adjective describes a day that is extremely hot—nearly unbearable.

  • It’s scorching hot out there. (“It’s scorching”) – incorrect grammar, but common.

  • It’s a real scorcher today. (functioning as a noun).


This is not a very commonly used word, but it’s still a great one to know if you want to sound advanced. Swelter describes an almost unbearable heat. Think of the hottest day you’ve ever experienced. This word can also be used as a verb, noun, or adjective if its form is changed.

  • The swelter of a July day. (noun)

  • The sweltering heat is almost unbearable. (adjective)

  • The driver sweltered in his car during the traffic jam. (verb)

Dog Days (Idiom)

This idiom can be used to express the period of summer when the temperature can always be described as hot. Simply put, the dog days of summer are the hottest days of summer.

  • I visited China during the dog days of summer.

  • I’ve always liked the dog days of summer—the heat rejuvenates me.

Some Slang to Try Out:

Steamer: It’s a real steamer out there.

Toasty: Man, it’s toasty today!

Piping: I don’t want to be out in a piping hot day like today.

Roasting: I’m roasting out here.

Blazing: It’s blazing hot!

Hotter than Hell / Hades: It’s hotter than Hades out here.
