כדאי לטייל בבוקר, כי בצהריים חם מדי.

כדאי is a very common Hebrew word meaning it’s כדאי to..., which is often best translated as it’s כדאי / advisable / a good idea / worth doing depending on context.

In כדאי לטייל בבוקר, it gives a general recommendation: It’s a good idea to go for a walk / travel in the morning.

A useful point: כדאי itself does not change for gender or number.

This sentence is making a general statement, so no specific person is mentioned.

If you want to say who the recommendation is for, Hebrew often adds a pronoun after כדאי:

• כדאי לי — it’s worthwhile for me
• כדאי לך — it’s worthwhile for you
• כדאי לנו — it’s worthwhile for us

For example:

• כדאי לי לטייל בבוקר — It’s a good idea for me to walk in the morning.
• כדאי לך לטייל בבוקר — You should walk in the morning / It’s a good idea for you to walk in the morning.

לטייל is the infinitive form of the verb, meaning to walk around, to go for a walk, to tour, or sometimes to travel, depending on context.

In Hebrew, infinitives usually begin with ל־, so:

• טייל is the verb root/form behind the idea
• לטייל = to walk / to stroll / to travel

After כדאי, Hebrew commonly uses the infinitive:

• כדאי ללמוד — It’s worth studying
• כדאי ללכת — It’s worth going
• כדאי לטייל — It’s worth going for a walk / traveling

It can cover several related ideas. לטייל often means to go out walking, to stroll, to tour, or to travel around. It is broader than just the basic act of walking.

So in this sentence, depending on the context, it could suggest:

• to go for a walk in the morning
• to go sightseeing in the morning
• to travel around in the morning

A plain to walk in the physical sense is often ללכת.

Because בבוקר is really made from:

• ב־ = in
• הבוקר = the morning

When ב־ attaches to a word with ה־, the forms combine, so ב + הבוקר becomes בבוקר.

So בבוקר literally means in the morning.

This is very common in Hebrew:

• בבית = in the house
• בשולחן = on the table
• בבוקר = in the morning

Because בוקר here behaves like a noun with the definite article: the morning, so ב + הבוקר becomes בבוקר.

But צהריים is often used as a fixed time expression without ה־ when it means noon / midday / afternoon. So Hebrew normally says:

• בצהריים — at noon / in the afternoon

not בצהריים with an article inserted.

Also, צהריים is a special word ending in ־יים, a form that historically relates to the dual.

בצהריים usually means at noon, around midday, or in the afternoon, depending on context.

In this sentence, since it contrasts with בבוקר, it means something like by midday / in the afternoon.

So the idea is:

• Morning = a better time to go out
• Midday/afternoon = too hot

Hebrew often leaves out the dummy subject it in weather expressions.

In English, you say:

• It is hot
• It is cold

In Hebrew, you usually just say:

• חם — hot
• קר — cold

So כי בצהריים חם מדי literally looks like because in the afternoon too hot, but natural English is because it’s too hot in the afternoon.

Because weather expressions in Hebrew are commonly said in an impersonal way, using the masculine singular form as the default:

• חם — hot
• קר — cold
• נעים — pleasant

Here, חם is not really agreeing with a feminine noun. It works like a general statement about the conditions: it’s hot.

So חם מדי is the normal way to say too hot.

מדי means too in the sense of excessively.

So:

• חם מדי = too hot
• חם מאוד = very hot

This is an important difference:

• מאוד just strengthens the adjective
• מדי means more than is desirable or comfortable

So the sentence says not just that it is hot, but that it is too hot.

Because in Hebrew, מדי usually comes after the adjective or adverb it modifies.

So:

• חם מדי — too hot
• יקר מדי — too expensive
• לאט מדי — too slowly

That word order is normal.

כי means because here. It introduces the reason for the recommendation.

So the structure is:

• כדאי לטייל בבוקר — It’s a good idea to go out in the morning
• כי בצהריים חם מדי — because in the afternoon it’s too hot

Hebrew uses כי very naturally to connect a statement and its reason.

Yes. Hebrew often places the time expression early in the clause:

• בצהריים חם מדי — In the afternoon, it’s too hot

That sounds very natural. Hebrew is often flexible with word order, especially with time and place phrases, but this version is completely standard.

A simple pronunciation guide would be:

kedái letayél babóker, ki batzohoráyim kham midái

Approximate stress:

• כדאי — ke-DAI
• לטייל — le-ta-YEL
• בבוקר — ba-BO-ker
• בצהריים — ba-tzo-ho-RA-yim
• מדי — mi-DAI

The ח in חם is a throaty sound that English does not really have. Many learners first pronounce it like h, which is understandable, but native Hebrew uses a rougher sound.
