Essential vocabulary for temperature and comfort
Start with core words you will hear and use most often. Learn the nouns, verbs, and adjectives related to temperature and comfort.
temperatura — temperature
quente — hot
frio — cold
confortável — comfortable
calor — heat
frio (noun) — cold (as a feeling or condition)
ar-condicionado — air conditioning
aquecimento — heating
After the first appearance, use temperatura, quente, frio, confortável, calor, ar-condicionado, and aquecimento for subsequent mentions.
Basic verbs and expressions to change the temperature
These verbs let you ask someone to change the setting, or tell someone how you feel.
aumentar — to increase
diminuir — to decrease
ligar — to turn on
desligar — to turn off
regular — to adjust
está — is (used with feelings and states)
Examples:
Por favor, você pode aumentar o ar-condicionado?
Faz um pouco de frio aqui, pode diminuir o ventilador?
Polite ways to ask for a temperature change
Politeness is important in Portuguese-speaking contexts. Use these softeners and modal verbs to sound natural.
Softening phrases:
por favor — please
poderia — could you (conditional polite)
você pode — can you (informal polite)
Polite requests:
Por favor, você pode diminuir a temperatura?
Usage note: poderia is slightly more formal and polite than você pode, which is common in casual conversations.
Natural phrases to express how you feel
Short sentences to explain whether you are hot or cold, and what you prefer.
Estou com calor — I am hot
Estou com frio — I am cold
Está muito quente — It is very hot
Está gelado — It is freezing / very cold
Examples:
Está muito quente aqui, você pode diminuir o ar-condicionado?
Estou com frio, você pode ligar o aquecimento?
How to set a specific temperature
If you need to be precise, use numbers and degrees. This is common in hotels or shared offices where thermostats have numerical settings.
Useful structure: coloque a temperatura em X graus / aumente para X graus / diminua para X graus
colocar — to set/put
graus — degrees
Examples:
Você pode colocar a temperatura em 22 graus, por favor?
Pode diminuir para 24 graus?
Usage note: In Brazil, Celsius is standard. Say 22 graus (vinte e dois graus).
Setting thermostats and remote controls
Learn phrases for common thermostat and remote actions: increase, decrease, switch modes, and set fan speed.
Commands and labels you might see on remotes:
ligar / desligar — turn on / turn off
modo — mode (cool, heat, fan)
ventilador — fan
auto — automatic mode
frio / quente — cool / heat
Examples:
Mude o modo para frio, por favor.
Coloque o ventilador em velocidade média.
Usage note: auto on many units keeps a stable temperatura automatically; you can ask a host or receptionist if you prefer automatic control.
Polite refusals and negotiation
Sometimes others prefer a different setting. These phrases help you negotiate and find a compromise.
Polite declines and proposals:
Desculpe, eu prefiro mais quente.
Tudo bem, que tal 23 graus?
Examples of compromise dialogues:
Pessoa A: Está muito frio para mim.
Pessoa B: Eu estou com calor — e se colocarmos 24 graus?
Usage note: Use desculpe to soften disagreement. Suggest a number or mode to move toward a solution.
Short dialogues for common situations
Here are natural mini-conversations you might use at home, in a hotel, or at work. Line breaks indicate different speakers.
Hotel reception
Recepcionista: Boa tarde, precisa de ajuda com a temperatura?
Hóspede: Sim, está muito quente no quarto. Pode diminuir o ar-condicionado?
Recepcionista: Claro, vou ajustar para 22 graus.
At home
Morador A: Está com muito frio aqui.
Morador B: Eu consigo sentir um pouco de frio, mas não tanto. Podemos tentar 23 graus?
Morador A: Combinado.
Office
Colega A: O ar-condicionado está muito forte.
Colega B: Você pode diminuir um pouco? Eu prefiro mais frio para trabalhar.
Colega A: Vou colocar no modo auto e baixar dois graus.
Common idioms and casual expressions
Besides direct phrases, Brazilians sometimes use informal expressions about temperature and comfort. These make conversations feel native.
Informal phrases:
tá um forno — it’s like an oven (very hot)
tá um gelo — it’s freezing (very cold casual)
tô morrendo de calor — I’m dying of heat (very informal)
Examples:
Hoje o escritório está tá um forno, será que dá para aumentar o ventilador?
Está tá um gelo aqui perto da janela.
Usage note: Save strongly informal phrases like tô morrendo de calor for friends, not formal settings.
Temperature-related adjectives and comparative forms
To compare conditions or express gradual change, use comparatives and adverbs.
Comparatives and adverbs:
mais — more
menos — less
muito — very
um pouco — a little
Examples:
Pode deixar um pouco mais quente? Estou com um pouco de frio.
Prefiro o ar-condicionado um pouco menos forte.
Practical tips for learners
Quick strategies to sound natural and avoid misunderstandings when discussing temperature.
1. Use numbers when possible. Saying 21 graus is clearer than vague terms.
2. Always add por favor to requests in formal or service contexts.
3. Match register: use poderia or o senhor/a senhora poderia in hotels and with older people.
4. Practice listening for thermostat labels like liga/desliga, frio/quente, and ventilador.
5. When unsure, propose a compromise number: que tal 23 graus? keeps interactions friendly.
Common mistakes and how to avoid them
Beginners often mix vocabulary or omit polite markers. Here are frequent errors and fixes.
Mistake 1: Using Portuguese word order incorrectly. Correct: Está muito quente aqui, not Aqui está muito quente in casual speech.
Mistake 2: Forgetting degrees. Always include graus when giving numeric settings.
Mistake 3: Overusing informal slang in formal contexts. Avoid tô morrendo de calor with hotel staff.
Extra phrases for specific contexts
Special phrases for cars, restaurants, and medical or sensitive situations where temperature matters.
In a car:
Pode ligar o ar-condicionado?
Está abafado, pode abrir o vidro um pouco?
In a restaurant:
Você pode ajustar o ar para não ficar tão gelado?
Está frio aqui perto da porta.
Usage note: In medical or health-sensitive contexts, be clear and calm. Say Estou com muito frio and ask for a blanket or to increase the aquecimento.
Resources to continue learning
