What day did God create wind?

According to tradition, God created the universe and all its contents from nothing (Exodus 20:11, Isaiah 40:28; Rashi commentary to Genesis 1:14; Maimonides' "Guide," 2:30; Nachmanides on Gen. 1:1). This includes wind. Rashi's commentary (Gen.1:14) explains that everything was actually created on the first day, though they didn't become functional until the stated day for each thing.
