Spanish Real Future Conditions with Si and the Future

For real or likely future conditions, Spanish uses present indicative after si—not the future—while the result can use future, present, or a command.

Spanish real future conditions: Use present after si and future in the result

The condition clause uses present indicative even though its meaning is future; the result can use simple future.

Si tengo tiempo, te llamaré.
If I have time, I will call you.Tengo is grammatically present but refers to a future condition.

Quick check

If it rains, we will stay home.

Combine a condition with a command

A present condition can lead to an affirmative or negative command for practical instructions.

Si ves a Ana, dile que llame.
If you see Ana, tell her to call.Ves states the real condition; dile gives the instruction.

Treat the condition as realistically possible

This pattern presents the condition as open or likely, unlike the imperfect-subjunctive pattern for a more hypothetical situation.

Si ahorro suficiente, viajaré este verano.
If I save enough, I will travel this summer.The speaker treats saving enough as a real possibility.

Common mistakes

Si tendré tiempo, te llamaré.

Si tengo tiempo, te llamaré.

Do not use the future directly after conditional si.

Si verás a Ana, dile.

Si ves a Ana, dile.

The si clause remains present indicative.

Si ahorrara suficiente, viajaré. (standard second conditional intended)

Si ahorrara suficiente, viajaría.

A hypothetical si clause pairs with conditional, not future.
