Não dá para sair agora porque está chovendo.

Here dá para + infinitive is a very common Brazilian Portuguese expression meaning it’s possible to, it works to, or in the negative, it’s not possible to / it won’t work to.

So:

Não dá para sair agora = It’s not possible to go out now / We can’t go out now

This use of dar is idiomatic. It does not literally mean give here.

You will hear this pattern a lot:

• Dá para esperar? = Is it possible to wait?
• Não dá para fazer isso hoje. = It’s not possible to do that today.
• Dá para ver daqui. = You can see it from here.

Because não dá para and não pode express different ideas.

• Não dá para sair agora = it’s not workable / not possible under the circumstances
• Não pode sair agora = you are not allowed to go out now, or you cannot due to a rule

In your sentence, the reason is porque está chovendo. Rain is a circumstance, not a rule, so não dá para sounds more natural.

Compare:

• Não dá para sair agora porque está chovendo. = We can’t go out now because it’s raining.
• Você não pode sair agora. = You can’t go out now. (for example, because someone says so)

Because this is an impersonal expression.

In não dá para sair, the verb dar is used in the 3rd person singular with no specific subject, similar to English it’s possible or you can’t in a general sense.

Portuguese often uses verbs impersonally like this:

• Dá para resolver. = It’s possible to solve it.
• Não dá para entender. = It’s not possible to understand.
• Dá para ir a pé. = It’s possible to go on foot.

There is no actual he/she/it doing the action of dar.

After dar in this expression, Portuguese normally uses para + infinitive to say to do something.

So:

• dá para sair = it’s possible to go out
• dá para comer = it’s possible to eat
• dá para ver = it’s possible to see

This pattern is very common and natural in Brazilian Portuguese.

You may also hear dá pra sair in speech and informal writing. Pra is just the contracted spoken form of para.

No, not in standard Portuguese.

With this expression, you normally need para:

• Não dá para sair agora. ✅
• Não dá sair agora. ❌

In everyday Brazilian speech, para is often reduced to pra, but it is still there grammatically:

• Não dá pra sair agora. ✅

Because adverbs like agora are flexible in Portuguese, and sair agora sounds very natural.

These are all possible, though not always equally natural in the same context:

• Não dá para sair agora.
• Agora não dá para sair.
• Não dá agora para sair. (possible, but less natural)

The version in your sentence is the most neutral and common for everyday speech.

Here porque is correct because it means because and introduces a reason.

• Não dá para sair agora porque está chovendo. = We can’t go out now because it’s raining.

Very short guide:

• porque = because
• por que = why / for which reason
• por quê = why, usually at the end of a question
• porquê = the reason, a noun

Examples:

• Por que você saiu? = Why did you leave?
• Você saiu por quê? = You left why?
• Ninguém sabe o porquê. = Nobody knows the reason.
• Saí porque estava cansado. = I left because I was tired.

Está chovendo uses estar + gerund, which is the normal Brazilian Portuguese way to emphasize an action happening right now.

So:

• Está chovendo. = It is raining. / It’s raining right now.
• Chove. = It rains / It is raining

In Brazil, está chovendo sounds especially natural when talking about the current moment. It highlights that the rain is ongoing now, which explains why going out is not possible.

Both can work, but está chovendo is more vivid and conversational here.

Because chover is usually an impersonal verb when referring to weather.

Just like English says it’s raining with a dummy it, Portuguese simply says:

• Está chovendo.
• Chove muito aqui.

There is no real subject. Portuguese does not need to add a word like English it.

This is also true of some other weather expressions:

• Está ventando. = It’s windy.
• Nevou ontem. = It snowed yesterday.

Yes, you could, but the nuance changes.

• Não dá para sair agora porque está chovendo. = Going out now is not really possible because of the situation.
• Não posso sair agora porque está chovendo. = I can’t go out now because it’s raining.

The second version sounds more personal, focused on me. The original sentence sounds more general and situational, almost like it just doesn’t work right now.

So both are correct, but não dá para is often more idiomatic in everyday Brazilian Portuguese for this kind of situation.

It is natural, everyday, and slightly informal-to-neutral.

You will hear it a lot in conversation. It is completely normal in speech and casual writing.

A more formal version could be:

• Não é possível sair agora porque está chovendo.

In conversation, many Brazilians would prefer:

• Não dá para sair agora porque está chovendo.
• Não dá pra sair agora porque está chovendo.

So the sentence is very useful for real-life Brazilian Portuguese.

Pra is the common spoken contraction of para in Brazilian Portuguese.

So these mean the same thing:

• Não dá para sair agora porque está chovendo.
• Não dá pra sair agora porque está chovendo.

Differences:

• para = more neutral in writing, more careful pronunciation
• pra = very common in speech and informal writing

If you are learning, it is good to recognize both. In real Brazilian conversation, pra is extremely frequent.

In casual speech, it often sounds more like:

Num dá pra sair agora porque tá chovendo.

That reflects common spoken reductions:

• não → num or nãu-like pronunciation
• para → pra
• está → tá

But in standard writing, the full form is:

Não dá para sair agora porque está chovendo.

So the written sentence is correct, and the reduced version helps you recognize how people may actually say it.
