Cover art for Mistral Wind lyrics by Heart

I don't usually like to assume a meaning when I can't find what the artist has said or written themselves, but it seems pretty obvious that the wind is a metaphor for a lover, or "being in love" situation ... where things were safe, but the love situation was windy and stormy in albeit exciting and heart-pounding ways, and you could just let the feeling blow over you and take you wherever it may. That rush of being in love. And now things are back to being calm again now that it's over, but man, do you miss those feelings.
