Dự báo thời tiết khiến tôi rối.

Dự báo means forecast or prediction, and thời tiết means weather. Together, dự báo thời tiết means weather forecast.

Even though the order may feel different from English, this is a normal Vietnamese noun phrase.

Vietnamese does not use articles like a, an, or the the way English does. So dự báo thời tiết can mean a weather forecast or the weather forecast, depending on context.

If the context already makes it clear which forecast is being talked about, no extra word is needed.

Khiến means to make, to cause, or to lead someone to feel/do something.

A very common pattern is:

X khiến Y + adjective/verb

In this sentence:

• X = Dự báo thời tiết
• Y = tôi
• result = rối

So the structure means: The weather forecast makes me confused.

In Vietnamese, pronouns do not change form the way they do in English. So tôi can mean both I and me, depending on its role in the sentence.

Here, tôi comes after khiến, so it functions like me in English:

Dự báo thời tiết khiến tôi rối
= The weather forecast makes me confused

Here, rối means confused, mixed up, or mentally tangled.

Literally, rối can also describe something physically tangled, like hair or string. In this sentence it is used figuratively, meaning the speaker’s thoughts feel tangled or unclear.

Rối is understandable, but many learners will also hear bối rối, which is very common.

There is a slight nuance:

• rối = confused, mentally tangled, mixed up
• bối rối = confused, flustered, awkward, unsure what to do

So:

• Dự báo thời tiết khiến tôi rối sounds like The weather forecast confuses me
• Dự báo thời tiết khiến tôi bối rối sounds a bit more like The weather forecast leaves me confused/flustered

If you mean pure mental confusion, rối works. If you mean a more emotional or awkward kind of confusion, bối rối may sound more natural.

Yes. Làm can also mean make in this kind of sentence.

So both are possible:

• Dự báo thời tiết khiến tôi rối
• Dự báo thời tiết làm tôi rối

In general:

• khiến often sounds a bit more formal or written
• làm often sounds more common in everyday speech

After khiến, Vietnamese can go straight to the result state without adding a verb like English be.

So:

• khiến tôi rối = makes me confused

This is normal Vietnamese grammar. The adjective rối directly describes the result caused by khiến.

Yes. The order is very natural:

Dự báo thời tiết + khiến + tôi + rối

That is basically: cause + make + person affected + result

This is a common Vietnamese pattern and lines up fairly closely with English: The weather forecast makes me confused

No specific tense is marked here. Vietnamese often leaves tense unstated unless it matters.

So Dự báo thời tiết khiến tôi rối could mean:

• The weather forecast confuses me
• The weather forecast is making me confused
• The weather forecast made me confused

If you want to make time clearer, you can add time words or markers such as:

• đã = past
• đang = ongoing
• sẽ = future

For example:

• Dự báo thời tiết đã khiến tôi rối. = The weather forecast confused me.

Yes, it is understandable and grammatically fine. However, depending on context, some speakers might prefer slightly different versions such as:

• Dự báo thời tiết làm tôi rối.
• Dự báo thời tiết khiến tôi bối rối.
• Bản dự báo thời tiết khiến tôi rối.

Adding bản can make it clearer that you mean the forecast report itself. Using bối rối can sound a bit more idiomatic in some situations. But the original sentence is still a valid sentence for a learner to study.
