Questions & Answers about Hoje o vento está muito forte.
In Portuguese, nouns almost always need an article (a word like o, a, os, as) unless there’s another determiner (like este, aquele, meu).
- O vento = the wind
- Just vento on its own is usually not a complete subject in standard speech.
In English, with weather we often drop the article:
- “Wind is strong today” (not typical, but possible)
- More often: “The wind is strong today” or “It’s windy today.”
Portuguese generally prefers O vento está muito forte over bare Vento está muito forte, which sounds wrong in normal sentences (you’d only see something like that in a headline: Vento muito forte hoje).
Portuguese has two verbs for “to be”: ser and estar.
- estar is used for temporary states, conditions, or current situations.
- ser is used for permanent or defining characteristics.
Weather conditions at a specific moment are seen as temporary:
- Hoje o vento está muito forte.
“Today the wind is very strong.” (right now; temporary)
If you talk about a place where the wind is always strong:
- Aqui o vento é muito forte.
“Here the wind is very strong.” (as a general, permanent trait of that place)
So with hoje (today), it’s clearly about the current, temporary situation, so está is the natural choice.
