"It is hot today."
Translation:Está quente hoje.
you use that for the condition of the atmosphere at a certain time/place. "Está quente hoje" (now) "Rio de Janeiro É muito quente" -- "Rio is really hot". In this case use the conjugation of the verb SER once it is a characteristic of the region. For a continuous weather, also use SER: This drought has been terrible -- essa seca tem SIDO horrível.
Can "quente" be used in multiple ways? Ex: hot food, people feeling hot from hot weather, appearance (like telling a woman she's hot)?
- hot food = comida quente.
- people feeling hot from hot weather = then, a pessoa está com calor.
- appearance (like telling a woman she's hot) = you can use quente in this context, but it is not common.
