Questions & Answers about Если погода тёплая, бельё высохнет быстрее.

Why is there a comma after тёплая?

In Russian, an если (if) clause is a subordinate clause. When it comes first, it is normally followed by a comma before the main clause:

• Если погода тёплая, бельё высохнет быстрее.
  If you reverse the order, the comma is still typically used:
• Бельё высохнет быстрее, если погода тёплая.

Can I add то (then) here: Если погода тёплая, то бельё высохнет быстрее?

Yes. То is optional and often used for emphasis or clarity, roughly if…, then…:

• Если погода тёплая, то бельё высохнет быстрее.
  Without то is also completely natural, especially in short sentences.
