في الصيف بنحب نصحى بدري ونروح البحر قبل ما الجو يبقى حر.

Because Egyptian Arabic usually builds the subject into the verb itself. The prefix نـ marks we.

• بنحب = we like
• نصحى = we wake up / to wake up depending on context
• نروح = we go / to go

You can add إحنا for emphasis, but it is not necessary.

In Egyptian Arabic, بـ often marks the normal present tense or a habitual action/state.

So بنحب means we like in a general, everyday sense. Since the sentence is talking about a usual summer habit, بـ is exactly what you would expect here.

After a verb like بنحب = we like, the next verb often appears in the bare imperfect without بـ. In English, this is often translated as to + verb.

So:

• بنحب نصحى = we like to wake up
• ونروح = and go / and to go

This is one of the ways Arabic expresses something like the English infinitive, since Arabic does not use to in the same way English does.

بدري means early.

In this sentence it works like an adverb:

• نصحى بدري = wake up early

It is a very common colloquial Egyptian word.

In Egyptian Arabic, with many common destinations, the verb راح / يروح can take the place directly, without a preposition.

For example:

• أروح البيت = go home
• أروح الشغل = go to work
• أروح البحر = go to the beach / sea

Using إلى would sound much more like Standard Arabic. In everyday Egyptian, نروح البحر is the natural choice.

Literally, البحر means the sea. But in everyday Egyptian, نروح البحر very often means go to the beach or go to the seaside.

So the exact English translation depends on context. In a summer sentence like this, the beach is often the most natural translation.

قبل ما is a very common Egyptian expression meaning before followed by a clause.

So:

• قبل ما الجو يبقى حر = before the weather gets hot

Here, ما is just part of this normal colloquial structure. You should learn قبل ما as a set phrase.

يبقى can have several meanings in Egyptian Arabic, including remain, be, or become, depending on context.

Here it means become / get:

• الجو يبقى حر = the weather gets hot

That is a very natural Egyptian way to express a change of state.

For weather, Egyptian Arabic commonly uses حر.

So:

• الجو حر = the weather is hot / it’s hot

حار exists, but حر is the more natural everyday Egyptian choice in this kind of sentence.

In Cairene Egyptian, ق is usually pronounced as a glottal stop. So يبقى is usually pronounced roughly yib’a or yeb’a, not like Standard Arabic yabqā.

This is a very common pronunciation feature in Egyptian Arabic.

Because ص is a sun letter, the ل of ال is assimilated in pronunciation.

So الصيف is pronounced roughly es-seef or ṣ-ṣēf, not al-sayf.

That means في الصيف is said roughly like fi s-seef in normal Egyptian speech.
