Anyway, I know I don’t speak prescriptively myself (US Midwestern dialect) and find the response to the question perfectly acceptable because there is no ambiguity to it. Some might say it’s redundant because sunny implies day, but hey, I have a sign in my office that says, “this office will not tolerate redundancy in this office” and lots of English native-speakers don’t get it!

The sign isn’t actually redundant. The first use of “this office” is referring to who won’t tolerate the redundancy, and the second refers to the scope in which redundancy will not be tolerated.

If you say so, redundant sign.
