На дачу я обычно беру шорты и сандалии, потому что там жарко и много солнца.

Дача is a country house or summer cottage, often used for weekends, gardening, or holidays.

In Russian, going to a dacha is normally expressed with на дачу, not в дачу. This is just the standard idiomatic pattern:

• ехать на дачу = to go to the dacha
• быть на даче = to be at the dacha

So:

• на дачу = to the dacha, toward it
• на даче = at the dacha

Even though English says to the house, Russian uses на here by convention.

Because дача changes case.

Here, на expresses motion toward a destination, so it takes the accusative case.
Дача is a feminine noun ending in -а, and its accusative singular is -у:

• дача = nominative
• дачу = accusative

The same pattern appears in many feminine nouns:

• мама → маму
• книга → книгу
• дача → дачу

Russian word order is flexible. The sentence starts with На дачу to set the scene first: as for going to the dacha...

So this order highlights the destination/topic first:

• На дачу я обычно беру...

Other orders are also possible:

• Я обычно беру шорты и сандалии на дачу
• Обычно я беру шорты и сандалии на дачу

They all mean roughly the same thing, but the emphasis changes slightly. In this sentence, starting with На дачу sounds very natural.

Обычно means usually.

It often appears near the verb, but Russian allows it to move around:

• Я обычно беру...
• Обычно я беру...
• На дачу я обычно беру...

These are all correct. The main difference is emphasis and rhythm, not basic meaning.

In this sentence, На дачу я обычно беру... sounds smooth and natural.

Because беру is the imperfective verb, and it fits a habitual action.

• беру = I take / I usually take
• возьму = I will take / I’ll take once, on a specific occasion

Since the sentence includes обычно, it describes a repeated habit, so беру is the right choice:

• На дачу я обычно беру... = When I go to the dacha, I usually take...

If you were talking about one future trip, you might say:

• На дачу я возьму шорты и сандалии = I’ll take shorts and sandals to the dacha

Because those words are normally used in the plural when talking about the clothing items themselves.

• шорты = shorts
• сандалии = sandals

This is similar to English, where shorts is also plural. Russian usually treats шорты as a plural noun.

In the sentence, they are direct objects, so they are in the accusative plural. But because they are inanimate, the accusative plural looks the same as the nominative plural:

• шорты → шорты
• сандалии → сандалии

Because потому что is the standard way to say because when introducing a reason clause.

So:

• потому что там жарко... = because it is hot there...

Потому by itself usually does not work the same way in a simple sentence like this. Russian normally uses:

• потому что = because
• поэтому = therefore / that’s why

Compare:

• Я беру шорты, потому что там жарко = I take shorts because it’s hot there
• Там жарко, поэтому я беру шорты = It’s hot there, so I take shorts

Because потому что introduces a subordinate clause, and Russian separates that clause with a comma.

Main clause:

• На дачу я обычно беру шорты и сандалии

Reason clause:

• потому что там жарко и много солнца

So the comma is required.

Жарко means it is hot or the weather/conditions are hot. It is used to describe an environment or situation.

• Там жарко = It’s hot there

Жаркий is an adjective, so it must describe a noun:

• жаркий день = a hot day
• жаркое лето = a hot summer

So in this sentence, жарко is correct because no noun is being described directly.

Because after много, Russian uses the genitive case.

The noun солнце becomes солнца:

• солнце = nominative
• солнца = genitive

So:

• много солнца = a lot of sun / sunshine

This is a very common pattern:

• много воды = a lot of water
• много времени = a lot of time
• много снега = a lot of snow

Because in the present tense, Russian often omits есть when English would use there is or there are.

So:

• там много солнца literally looks like there much sun
• but it means there is a lot of sun or it gets a lot of sun there

Likewise:

• там жарко = it’s hot there

This omission is completely normal in Russian present-tense sentences.

In this context, много солнца means a lot of sun in the sense of sunlight or sunshine.

It does not mean there are many suns. Russian often uses солнце this way when talking about weather and climate:

• Сегодня много солнца = There’s a lot of sunshine today
• Летом здесь много солнца = There’s a lot of sun here in summer

So the phrase is very natural.

Yes. Russian allows several word orders, for example:

• Я обычно беру на дачу шорты и сандалии...
• Обычно я беру шорты и сандалии на дачу...
• Шорты и сандалии я обычно беру на дачу...

These versions are all grammatical, but they emphasize different things.

The original:

• На дачу я обычно беру шорты и сандалии...

puts the trip to the dacha first, which makes that setting feel like the starting point of the statement.
