How to Say “It’s Hot Today” in Spanish

Introduction

When summer arrives in Spanish-speaking countries, one phrase you’ll hear constantly is how people talk about the heat. Learning to express temperature naturally in Spanish goes beyond simple translation—it involves understanding cultural expressions, regional variations, and the grammatical structure that makes Spanish unique from English.

The Most Common Way: Hace Calor Hoy

The standard expression for commenting on hot weather in Spanish is hace calor hoy. This phrase literally translates to it makes heat today, though we would say it’s hot today in English. The verb hacer (to make or to do) is the key to discussing weather in Spanish, which differs significantly from English’s use of the verb to be.

Here’s the breakdown:
Hace – third person singular of hacer (it makes)
Calor – heat (noun)
Hoy – today

Notice that calor is a noun, not an adjective. You’re literally saying it makes heat rather than it is hot. This construction is essential for weather expressions in Spanish and cannot be substituted with the verb estar or ser when talking about temperature.

Why We Use Hacer Instead of Estar

English speakers often want to say está caliente when describing hot weather, but this is incorrect. The adjective caliente refers to objects that are hot to the touch, like food or water. Using está caliente for weather would sound very strange to native speakers.

The verb hacer is impersonal in weather expressions, meaning there’s no specific subject performing the action. This is similar to how we use it in English weather expressions—the it doesn’t refer to anything specific. In Spanish, this impersonal quality is built into the third-person singular conjugation of hacer.

Adding Intensity: Very Hot, Extremely Hot, and Beyond

To emphasize just how hot it is, Spanish offers several options. The most straightforward is hace mucho calor, where mucho (much/a lot) intensifies the heat. This translates to it’s very hot or it’s really hot.

For even greater emphasis, you can say:
Hace muchísimo calor – It’s extremely hot
Hace un calor tremendo – It’s tremendously hot
Hace un calor insoportable – It’s unbearably hot
Hace un calor espantoso – It’s terribly hot

Each of these expressions adds a different flavor of intensity. The suffix -ísimo attached to mucho creates the superlative form, indicating an extreme degree. Meanwhile, adjectives like tremendo, insoportable, and espantoso provide vivid descriptions that native speakers commonly use.

Regional and Colloquial Expressions

Spanish speakers across different countries have developed colorful ways to complain about the heat. In Mexico, you might hear hace un calorón, where the augmentative suffix -ón emphasizes the intensity. This is similar to saying it’s really hot with extra emphasis.

In Spain, people often say hace un calor del demonio or hace un calor de muerte, both hyperbolic expressions that roughly mean it’s hellishly hot. These phrases add drama and humor to weather complaints.

Latin American countries have their own variations:
Está que arde (Colombia, Venezuela) – It’s burning hot
Hace un sol de justicia (various countries) – The sun is blazing
Está hirviendo (various countries) – It’s boiling

While está que arde and está hirviendo use the verb estar, they’re idiomatic expressions rather than literal weather statements, which is why they don’t follow the standard hacer construction.

Talking About Personal Heat: Tengo Calor

When you want to express that you personally feel hot, rather than commenting on the weather in general, Spanish uses tengo calor (I have heat). This construction uses the verb tener (to have) instead of hacer.

The complete conjugation is:
Tengo calor – I’m hot
Tienes calor – You’re hot
Tiene calor – He/she is hot
Tenemos calor – We’re hot
Tenéis calor – You all are hot (Spain)
Tienen calor – They’re hot / You all are hot

Again, notice that calor remains a noun. You literally say I have heat rather than I am hot. Just like with weather, you cannot use estoy caliente to mean you feel hot—this phrase has a different meaning that could cause embarrassment.

Useful Related Phrases for Hot Weather

Beyond simply stating that it’s hot, knowing related expressions will help you engage in fuller conversations about the weather. Here are essential phrases:

¿Qué temperatura hace? – What’s the temperature?
Hace treinta grados – It’s thirty degrees
El pronóstico dice que va a hacer calor – The forecast says it’s going to be hot
Necesito aire acondicionado – I need air conditioning
Busquemos la sombra – Let’s find some shade
Esto está sofocante – This is suffocating/stifling

When asking about temperature, remember that most Spanish-speaking countries use Celsius rather than Fahrenheit. Thirty degrees Celsius equals eighty-six degrees Fahrenheit, which would indeed be quite hot.

Comparing Hot and Cold: The Hacer Structure

The hacer construction works for all weather-related temperature expressions. Understanding the parallel with cold weather helps solidify this pattern:

Hace calor – It’s hot
Hace frío – It’s cold
Hace fresco – It’s cool/chilly
Hace buen tiempo – The weather is nice
Hace mal tiempo – The weather is bad

Just as you can say hace mucho calor for very hot, you can say hace mucho frío for very cold. The structure remains consistent, making it easier to discuss various weather conditions once you master this pattern.

Common Mistakes to Avoid

English speakers learning Spanish often make predictable errors when discussing temperature. The most common mistake is using está caliente for weather, which native speakers never do. Remember that caliente describes the physical temperature of touchable objects—like el café está caliente (the coffee is hot).

Another error is forgetting that calor and frío are nouns, not adjectives. You cannot say hace caluroso even though caluroso is an adjective meaning hot or warm. The standard weather expression always uses the noun calor with hacer.

Additionally, don’t confuse personal feelings with weather conditions. Hace calor comments on the temperature outside, while tengo calor expresses your personal sensation. These are different contexts requiring different verbs.

Cultural Context: Heat in Spanish-Speaking Countries

Understanding how to talk about heat in Spanish connects to cultural practices in Spanish-speaking regions. Many countries have traditions built around coping with hot weather—the afternoon siesta in Spain, for example, developed partly because of intense midday heat.

In conversation, complaining about the weather serves as a social bonding activity, just as it does in English-speaking countries. Knowing these phrases helps you participate in small talk, show empathy when others mention the heat, and navigate daily life during hot seasons.

Many Spanish-speaking countries experience extreme heat during certain months, making weather commentary a frequent topic. Being able to discuss temperature naturally will enhance your interactions and demonstrate cultural understanding beyond basic vocabulary.

Conclusion

Mastering how to say it’s hot today in Spanish requires understanding the unique hacer construction that differs from English grammar. Whether you use hace calor hoy, hace muchísimo calor, or regional expressions like hace un calorón, you’re now equipped to discuss hot weather like a native speaker while avoiding common mistakes that mark you as a beginner.
