Does perhaps need a comma if at the beginning of sentence?

It's not grammatically correct to start a sentence with "perhaps" and then immediately follow it with a comma.

Here's why:

* "Perhaps" is an adverb that usually functions as a modifier, introducing an idea or possibility.

* Commas are used to separate elements within a sentence. You wouldn't separate an adverb from the rest of the sentence with a comma.

Example:

Incorrect: Perhaps, the weather will be better tomorrow.

Correct: Perhaps the weather will be better tomorrow.
