Şubat ayında hava hâlâ soğuk oluyor, bu yüzden kışlık kaban giyiyorum.

Şubat ayında literally means in the month of February.

• Şubat = February
• ay = month
• ayında = in its month / in the month

So Şubat ayında is a fuller, slightly more formal way to say in February.

A very common shorter version is:

• Şubatta = in February

So both of these can work:

• Şubat ayında hava hâlâ soğuk oluyor.
• Şubatta hava hâlâ soğuk oluyor.

The first one sounds a bit more explicit; the second is more compact and very natural.

It breaks down like this:

• ay = month
• -ı / -i / -u / -ü = 3rd person possessive suffix
• -nda / -nde = locative ending after that possessive form

So:

• ay → ayı = its month / the month
• ayı
  • -nda → ayında = in the month

In Şubat ayında, Turkish is using a noun phrase that is basically:

• Şubat ayı = the month of February
• Şubat ayında = in the month of February

This kind of structure is very common in Turkish.

Turkish does not have articles like the or a/an.

English says:

• the weather
• a winter coat
• the month of February

Turkish simply says:

• hava = weather / the weather
• kaban = coat / a coat / the coat, depending on context
• Şubat ayı = the month of February

Context tells you whether English would use a or the.

Hâlâ means still.

So:

• hava hâlâ soğuk = the weather is still cold

The circumflex in hâlâ helps distinguish it from hala, which can mean paternal aunt in standard spelling.

So:

• hâlâ = still
• hala = aunt

In everyday writing, people sometimes leave the circumflex out, but in careful writing hâlâ is preferred.

Both are possible, but they feel slightly different.

• Hava hâlâ soğuk. = The weather is still cold.
• Hava hâlâ soğuk oluyor. = The weather is still cold / tends to be cold / is still usually cold.

In this sentence, oluyor adds a sense of a recurring or typical situation. It makes the statement sound more like a general observation about February.

So the difference is roughly:

• soğuk = simple state
• soğuk oluyor = that state regularly happens / is typically the case

This use of oluyor is very natural in Turkish when talking about seasonal or habitual conditions.

Oluyor comes from olmak, which usually means to be, to become, or to happen, depending on context.

Here it is functioning in a habitual/descriptive way:

• hava soğuk oluyor = the weather is cold / tends to be cold

It is not really becoming cold in the dramatic sense. Instead, it means something like:

• it is usually cold
• it stays cold
• it tends to be cold

So in this sentence, oluyor helps express a general seasonal pattern.

This is a very common thing for English speakers to notice.

In Turkish, the -yor form is not only used for actions happening right now. It can also describe:

• habits
• repeated actions
• general present situations
• things that are currently true over a period of time

So:

• giyiyorum can mean I am wearing or I wear
• oluyor can mean it is happening / it becomes or it tends to be

In this sentence:

• hava hâlâ soğuk oluyor = a general truth about February
• kaban giyiyorum = what I usually wear in that situation

So the Turkish present continuous often covers both present and habitual present meanings.

Yes. Bu yüzden is a very common fixed expression meaning:

• because of this
• for this reason
• therefore
• so

In this sentence:

• hava hâlâ soğuk oluyor = the weather is still cold
• bu yüzden = for that reason / so
• kışlık kaban giyiyorum = I wear a winter coat

So the whole flow is:

• The weather is still cold, so I wear a winter coat.

Other similar connectors include:

• bu nedenle = for this reason
• o yüzden = that’s why / so
• bu sebeple = for this reason

Kışlık means for winter or winter-type.

It comes from:

• kış = winter
• -lık / -lik / -luk / -lük = a suffix that can create meanings like for, suitable for, or related to

So:

• kışlık kaban = winter coat
• literally: winter-use coat

You can see the same pattern in other words:

• yazlık = for summer / summer place / summer clothes, depending on context
• günlük = daily / diary, depending on context
• yağmurluk = raincoat

So kışlık describes the type or purpose of the coat.

Yes, kaban already means coat, usually an outer coat. But kışlık adds extra information: it is specifically a winter coat, not just any coat.

Compare:

• kaban = coat
• kışlık kaban = winter coat

So kışlık narrows the meaning. It tells you the coat is suitable for cold weather.

These words overlap a bit, but they are not identical.

• kaban = coat, usually a heavier outer coat
• ceket = jacket, often lighter and shorter
• mont = jacket/coat, often sporty or padded, especially in modern everyday speech

So in a winter sentence like this, kaban suggests a proper coat, which fits well with cold February weather.

It can mean either one, depending on context.

• giyiyorum literally is the -yor form of giymek = to wear / to put on
• In context, it often means I wear as a habit

Here the sentence is about a general situation in February, so giyiyorum is best understood as:

• I wear a winter coat
• or I’m wearing a winter coat in the sense of what I do during that period

So the English translation usually chooses the habitual meaning:

• I wear a winter coat

It comes from the verb giymek = to wear / to put on.

The stem is giy-, and then Turkish adds the present continuous ending:

• giy-
• -iyor
• -um = I

So:

• giyiyorum = I am wearing / I wear

Some other forms are:

• giyiyorsun = you wear / are wearing
• giyiyor = he/she/it wears / is wearing
• giyiyoruz = we wear / are wearing

Because Turkish verbs already show the subject.

In giyiyorum, the ending -um tells you the subject is I.

So Turkish does not need to say ben unless there is a special reason, such as contrast or emphasis.

• kışlık kaban giyiyorum = I wear a winter coat
• ben kışlık kaban giyiyorum = I wear a winter coat

Using ben is possible, but not necessary here.

Turkish word order is flexible, but the usual neutral order is Subject–Object–Verb, and the main verb often comes at the end.

Here:

• Şubat ayında = in February
• hava hâlâ soğuk oluyor = the weather is still cold
• bu yüzden = so / for this reason
• kışlık kaban giyiyorum = I wear a winter coat

The final verb giyiyorum comes at the end, which is very natural in Turkish.

English prefers:

• In February, the weather is still cold, so I wear a winter coat.

Turkish prefers:

• In February, the weather is still cold, so a winter coat wear-I.

That last version is not good English, of course, but it shows the Turkish structure more literally.

Yes. A simpler and very natural version would be:

• Şubatta hava hâlâ soğuk, bu yüzden kışlık kaban giyiyorum.

This version is shorter because:

• Şubat ayında becomes Şubatta
• soğuk oluyor becomes simply soğuk

Both versions are correct. The original sentence is completely natural, but this shorter version may feel easier for a learner to process.

A word-for-word style translation would be something like:

• Şubat ayında = in the month of February
• hava = the weather
• hâlâ = still
• soğuk oluyor = is being / tends to be cold
• bu yüzden = because of this / so
• kışlık kaban = winter coat
• giyiyorum = I wear / I am wearing

So a very literal version is:

In the month of February, the weather is still cold, so I wear a winter coat.

That is also the most natural English translation.
