الجو بارد في الخريف.

In Arabic, especially in the present tense, you usually do not say a separate word for is / am / are.

So:

• الجو بارد = The weather is cold

This is completely normal in both Standard Arabic and Egyptian Arabic.

If you wanted past or future, then Arabic would usually add something:

• كان الجو بارد = The weather was cold
• الجو هيبقى بارد in Egyptian = The weather will be cold

So in your sentence, the is is simply understood.

الجو means the weather or sometimes the atmosphere / the air, depending on context.

In this sentence, it clearly means:

• الجو = the weather

In Egyptian pronunciation, it is often said as el-gaww.

A useful thing to remember is that Arabic often uses the weather as the subject in sentences where English also says the weather:

• الجو حر = The weather is hot
• الجو جميل = The weather is nice
• الجو بارد = The weather is cold

Because Arabic normally puts the noun first and then the adjective/predicate in this kind of sentence.

So:

• الجو بارد literally: the weather cold natural English: the weather is cold

This is a very common Arabic sentence pattern.

It is called a nominal sentence: a sentence that starts with a noun rather than a verb.

Yes. بارد means cold, and here it is the masculine singular form.

That matches الجو, which is treated as masculine singular.

You may also see related forms:

• باردة = cold for a feminine singular noun
• برد in Egyptian can also be used as a noun meaning cold or as a more colloquial way to talk about cold weather in some expressions

In this sentence, بارد is the standard adjective meaning cold.

في means in.

So:

• في الخريف = in the autumn / in the fall

It is a very common preposition in Arabic and Egyptian:

• في البيت = in the house
• في مصر = in Egypt
• في الصيف = in the summer

In pronunciation, في الخريف is often said smoothly as fil-kharīf in connected speech.

الخريف means autumn or fall.

Yes, it is understood and used in Egyptian Arabic. It is also the normal Standard Arabic word.

So:

• الخريف = autumn / fall

Other seasons are:

• الصيف = summer
• الشتا / الشتاء = winter
• الربيع = spring

In Egyptian speech, people may use slightly more colloquial pronunciation, but الخريف is absolutely recognizable and normal.

Arabic often uses the definite article الـ with seasons in cases where English does not necessarily use the.

So Arabic says:

• في الخريف = literally in the autumn
• but in natural English this is just in autumn or in the fall

This is a normal difference between the two languages. You should not try to match English article usage word-for-word.

It can work in both, but it feels a bit closer to a neutral/standard-style sentence that is also easily understood in Egyptian Arabic.

In Egyptian Arabic, people might also say things like:

• الجو بارد في الخريف
• الجو بيبقى بارد في الخريف = The weather tends to be cold in the fall
• الدنيا بتبرد في الخريف = It gets cold in the fall

So your sentence is perfectly understandable for an Egyptian learner context, even if everyday spoken Egyptian sometimes uses slightly different phrasing.

A common Egyptian-style pronunciation would be:

• el-gaww bārid fil-kharīf

A few pronunciation notes:

• الـ is usually pronounced el-
• جو is often pronounced gaww in Egyptian
• في الخريف often sounds like fil-kharīf when spoken smoothly
• خ is a throaty sound, like the ch in German Bach or Scottish loch

So the full sentence in Egyptian pronunciation is often close to:

• el-gaww bārid fil-kharīf

Because الجو بارد and الجو البارد do not mean the same thing.

• الجو بارد = The weather is cold
• الجو البارد = the cold weather

This is an important difference.

When the adjective is part of the predicate, as in the weather is cold, it does not take الـ.

When the adjective directly describes a noun inside a noun phrase, both usually take الـ:

• الجو البارد = the cold weather
• البيت الكبير = the big house

So in your sentence, بارد is not just modifying the noun; it is telling you something about the noun.

Yes, but there is a difference in style.

• الطقس = the weather in a more formal or technical sense
• الجو = the weather / the atmosphere, and it is very common in everyday speech

So:

• الطقس بارد في الخريف is possible, but sounds more formal
• الجو بارد في الخريف sounds more natural in everyday conversation

For Egyptian Arabic, الجو is usually the more common everyday choice.

Yes. In natural English, both are good translations.

Arabic often uses الجو where English might use either:

• The weather is cold in autumn
• It’s cold in autumn

So even though the Arabic literally mentions the weather, the natural meaning can be expressed in English in more than one way.

The basic and most natural order is:

• الجو بارد في الخريف

That is the clearest default pattern: subject + description + time phrase

You may sometimes hear variations for emphasis, such as moving في الخريف earlier, but for learners, the safest pattern is the one in your sentence.

So if you are building similar sentences, this pattern is very useful:

• الجو حر في الصيف = The weather is hot in summer
• الجو معتدل في الربيع = The weather is mild in spring
• الجو بارد في الخريف = The weather is cold in autumn
