When the independent clause comes before the dependent clause, you do not typically need a comma between them, unless the dependent clause is nonessential or adds additional information that requires a pause. Here are some examples to illustrate:

No comma: "I will go for a walk if the weather is nice."

Comma: "I will go for a walk, if you're wondering, once the rain stops." Here, the dependent clause "if you're wondering" is nonessential and adds extra information.
