Si fa sol dissabte, volem fer una festa al parc.

Fa sol is the normal Catalan way to say it is sunny.

Literally, it is something like it makes sun, which sounds strange in English, but it is a very common weather pattern in Catalan. Catalan often uses fer for weather expressions:

• fa sol = it is sunny
• fa fred = it is cold
• fa calor = it is hot
• fa vent = it is windy

So even though fer often means to do or to make, here it is just part of a fixed weather expression.

There is no real subject stated.

This is an impersonal expression. In English, we often use a dummy subject like it in it is sunny, but Catalan does not need that here. So fa sol works on its own.

You do not need to add a subject pronoun.

Because in Catalan, a real future condition is very often expressed with the present tense, especially after si.

So:

• Si fa sol dissabte... = If it’s sunny on Saturday...

Even though Saturday is future in meaning, the present tense is the normal choice.

The main clause also uses the present:

• volem fer una festa = we want to have a party

This can express a present intention or plan about the future.

Catalan often does this where English may also use present in the if clause, but sometimes English speakers expect more future marking than Catalan actually uses.

Normally, no.

After si in this kind of conditional sentence, Catalan usually uses the present, not the future:

• Si fa sol dissabte, ... ✅
• Si farà sol dissabte, ... ❌ in normal usage

This is similar to English, where we say:

• If it’s sunny on Saturday... not
• If it will be sunny on Saturday...

So fa is the natural form here.

Volem fer means we want to have / we want to do. It emphasizes intention or desire.

So the sentence means that this is the plan or wish:

• Si fa sol dissabte, volem fer una festa al parc.

If you said:

• Si fa sol dissabte, farem una festa al parc.

that would sound more like If it’s sunny on Saturday, we’ll have a party in the park — more definite and decided.

So:

• volem fer = we want / we intend to
• farem = we will do

Both are possible in different contexts, but they are not exactly the same in tone.

Yes, but fer is extremely common in Catalan and is used in many expressions where English would choose a different verb.

Fer una festa means to have / throw a party.

So even though the literal idea is make/do a party, the natural English translation is usually:

• have a party
• throw a party

This is just a normal Catalan collocation.

A useful warning: fer festa without una can mean something different, often more like to have the day off or not work in some contexts. So fer una festa is clearer when you mean an actual party.

Because festa here is a countable noun meaning a party, so Catalan normally uses an article:

• fer una festa = to have a party

Without una, the phrase would not mean the same thing here.

As mentioned above, fer festa is a separate expression with a different meaning in many contexts, so una is important.

Because a + el contracts to al in Catalan.

So:

• a + el parc → al parc

This is completely standard.

Other common contractions include:

• de + el → del

Examples:

• al parc = to the park / in the park
• del parc = from the park / of the park

In Catalan, time expressions with days of the week often do not need a preposition where English uses on.

So:

• dissabte = Saturday / on Saturday

That is perfectly normal.

Here, Si fa sol dissabte means If it’s sunny on Saturday.

Catalan often leaves out the equivalent of English on in this kind of expression.

Yes. Si dissabte fa sol is also possible.

Both are understandable:

• Si fa sol dissabte, ...
• Si dissabte fa sol, ...

The difference is mostly about rhythm or emphasis, not basic meaning.

The version in your sentence is very natural and neutral. Putting dissabte earlier can slightly highlight the time more.

Not always.

Volem literally means we want, but in real conversation it can also sound like:

• we’d like to
• we’re planning to
• our idea is to

So in this sentence, it may express desire, intention, or a plan, depending on context.

That is why volem fer una festa can feel a little softer and less final than farem una festa.
