When the temperature rises and the sun blazes down, we often use the phrase "baking hot" to describe the intense heat. However, there are quite a few synonyms you can use to mix up your vocabulary and keep your descriptions fresh. For example, you can say it's scorching, sweltering, blistering, boiling, roasting, or broiling outside. You can also use idiomatic expressions like "hotter than a frying pan," "as hot as Hades," or "so hot you could fry an egg on the sidewalk." Using a variety of synonyms will make your writing more interesting and engaging, especially if you're describing a setting or a character's experience.
