Learn Hardcore Serbian: Ako bude sunce, sutra ćemo biti na plaži od jutra do večeri. - If it is sunny, tomorrow we will be at the beach from morning to evening.

Breakdown of Ako bude sunce, sutra ćemo biti na plaži od jutra do večeri.

Why is it Ako bude sunce and not Ako će biti sunce?

In Serbian, after ako when you talk about a future condition, you normally do not use će in that clause.

So Serbian says:

Using Ako će biti sunce sounds wrong or at least very unnatural in standard Serbian.

This is similar to English, where we say If it is sunny tomorrow..., not If it will be sunny tomorrow...

What exactly is bude? I thought the present of biti was je.

That is a very common question.

Serbian biti has two sets of forms that learners notice early:

sam, si, je, smo, ste, su
These are the usual present/auxiliary forms.
budem, budeš, bude, budemo, budete, budu
These are full verb forms used in certain constructions, especially in future-related and conditional contexts.

Here, bude is the 3rd person singular form from that second set.

So:

In your sentence, bude is exactly the form Serbian needs after ako for this kind of future condition.

Does literally mean ? Is that a normal way to talk about weather?
