Da quando è arrivato giugno, faccio colazione sul balcone ogni mattina.

Here da quando means since in a time sense: since the time that.

So:

• Da quando è arrivato giugno = Since June arrived / Since June began

In more natural English, you would usually say since June started or since June came around, but Italian often uses arrivare with time periods like months or seasons.

Yes. In Italian, arrivare is commonly used not only for people but also for times, dates, seasons, and events.

So these are normal:

• È arrivato giugno = June has arrived / June has come
• È arrivata l’estate = Summer has arrived
• Quando arriva Natale... = When Christmas comes...

It sounds perfectly natural in Italian, even if English often prefers June started or June has begun.

Because arrivare usually takes essere as its auxiliary in compound tenses.

So:

• è arrivato giugno
• not ha arrivato giugno

This is a common pattern with many intransitive verbs of movement or change of state, such as:

• andare → è andato
• venire → è venuto
• partire → è partito
• arrivare → è arrivato

Also notice that the past participle agrees with the subject when essere is used:

• È arrivato giugno because giugno is masculine singular
• È arrivata l’estate because estate is feminine singular

Because the sentence describes something that started in the past and is still true now.

• Da quando è arrivato giugno sets the starting point
• faccio colazione sul balcone ogni mattina describes a habit that continues into the present

Italian often uses the present tense in the main clause for actions that began in the past and still continue.

Compare:

• Da due anni vivo a Roma. = I have been living in Rome for two years.
• Da quando è arrivato giugno, faccio colazione sul balcone ogni mattina. = Since June began, I have breakfast on the balcony every morning.

English often uses have been doing or have done here, but Italian commonly uses the present.

Not in this sentence if you mean a repeated habit that still continues.

• faccio colazione = I have breakfast / I eat breakfast
• ho fatto colazione = I had breakfast / I have eaten breakfast

Because ogni mattina shows a regular repeated action, the present tense faccio is the natural choice.

If you said ho fatto colazione, it would sound like a completed event, not an ongoing habit.

Fare colazione is the standard Italian expression for to have breakfast.

Italian uses fare in many everyday expressions:

• fare colazione = to have breakfast
• fare pranzo = to have lunch
• fare una passeggiata = to take a walk
• fare sport = to do sports

So faccio colazione is the normal idiomatic way to say I have breakfast.

You could say something with mangiare if you want to focus specifically on eating, but fare colazione is the usual expression.

Because sul means on the and is the natural choice here.

• su + il = sul

So:

• sul balcone = on the balcony

In English we often say on the balcony, and Italian matches that here.

Nel balcone would mean in the balcony, which usually does not fit this idea.

In Italian, months normally do not take an article when used in a general time expression like this.

So:

• è arrivato giugno
• a giugno
• a maggio
• a settembre

That is normal.

Sometimes you may see an article with months in special cases, but here no article is needed.

Also note that month names in Italian are normally not capitalized, so giugno, not Giugno, unless it starts a sentence.

Italian word order is flexible, and this order is very natural.

• È arrivato giugno puts focus on the event: June has arrived
• Giugno è arrivato is also possible, but it can feel more marked or contrastive depending on context

With seasons, months, and other things that are coming/arriving, Italian often places the noun after the verb.

So è arrivato giugno sounds completely normal.

Because Italian usually drops subject pronouns when the verb ending already makes the subject clear.

• faccio already means I do / I have
• so io faccio is usually unnecessary unless you want emphasis or contrast

For example:

• Da quando è arrivato giugno, faccio colazione sul balcone ogni mattina. = neutral
• Io faccio colazione sul balcone, non in cucina. = I have breakfast on the balcony, not in the kitchen

So leaving out io is the normal choice.

Ogni mattina means every morning and shows that this is a repeated habit.

It tells you the action is not happening just once:

• faccio colazione sul balcone ogni mattina = I have breakfast on the balcony every morning

Without ogni mattina, the sentence would still be grammatical, but it would give less explicit information about frequency.

Yes. Italian allows some flexibility, though the original sounds very natural.

Possible variations:

• Da quando è arrivato giugno, ogni mattina faccio colazione sul balcone.
• Faccio colazione sul balcone ogni mattina da quando è arrivato giugno.

These all mean basically the same thing, but the emphasis shifts slightly.

The original version is smooth and idiomatic:

• first the time frame (Da quando è arrivato giugno)
• then the main habit (faccio colazione sul balcone ogni mattina)

It is talking about a continuing situation.

The structure is:

• a starting point in the past: Da quando è arrivato giugno
• a present habit still true now: faccio colazione sul balcone ogni mattina

So the meaning is not I started once and stopped, but rather this has been my routine since June began.

That is why the combination of da quando + past event + present tense is important here.
