Está muito quente.

Use Está muito quente. for any situation where the temperature is high. This could be a sunny day at the beach, a stuffy room without air conditioning, or even a spicy meal that’s making you sweat. It’s versatile for both outdoor and indoor environments. You can use it to describe the air, a place, or even a situation that feels 'heated' metaphorically, though its primary use is literal weather.

This phrase is wonderfully flexible! It sits comfortably in most everyday situations. You can say it to your best friend, your grandma, or even a stranger you're sharing a sweaty bus ride with. While it's not formal enough for a presidential address, it's polite enough for most casual interactions. Think of it as your default setting for talking about heat.

• On a scorching summer day, you might say to a friend, Nossa, está muito quente hoje! (Wow, it's very hot today!).
• Inside a car with no AC, you could tell the driver, O carro está muito quente. (The car is very hot).
• After eating a fiery piri-piri chicken, you might exclaim, Ai, essa comida está muito quente! (Ouch, this food is very hot!).
• Even in a crowded, unventilated concert venue, you might hear someone mutter, Este lugar está muito quente. (This place is very hot).

Use Está muito quente. when the heat is noticeable and perhaps a bit intense. It’s perfect for commenting on peak summer days, humid afternoons, or any time you feel genuinely warm. It's also great for acknowledging extreme conditions, like a heatwave. If you’re sweating profusely or seeking shade, this phrase is your cue. It’s also useful when you need to explain why someone might be uncomfortable or lethargic.

Avoid using Está muito quente. for mild warmth or pleasant sunshine. If it's just a 'nice warm day,' you'd use something milder like Está calor. (It's warm). Don't use it for things that are literally on fire, like a barbecue grill – that's fogo (fire). Also, avoid it for describing someone's anger or passion unless you're being very metaphorical and your audience will definitely get the joke. Stick to the weather!

Learners sometimes mix up quente (hot) with calor (heat/warmth). Remember, Está muito quente describes the *state* of being hot, while Está calor is more about the general condition of warmth. Another common slip is forgetting the verb Está altogether, which makes the phrase incomplete. It's like saying 'Very hot!' without the 'It is.'

✗ O sol está quente. (While true, it's less common than saying the *day* or *weather* is hot).

In Portugal, you might hear Está um calor do caraças! which is a very informal and emphatic way to say 'It's extremely hot!' In Brazil, especially in more casual settings, people might say Tá muito quente. (Tá is a common contraction of Está). Some might even say Que calor! (What heat!) as a more exclamatory version. For a slightly more formal tone, you might just say A temperatura está elevada. (The temperature is elevated).

• What's the difference between quente and calor? Quente is an adjective meaning 'hot', used with estar (like está quente). Calor is a noun meaning 'heat' or 'warmth', often used like Está calor (It's warm/hot) or Que calor! (What heat!).
• Can I use it for spicy food? Yes! If the food is literally spicy and makes you feel hot, you can say Está muito quente. It's a common way to describe spicy dishes.
• Is it okay to use in a professional email? Generally, no. Unless the heat is a significant factor impacting work (like a broken AC in the office), it's too informal. Stick to neutral descriptions like 'high temperatures'.
