This is how I feel about riding in the rain to work. Like yes you get wet but also are you unable to get wet? If you want, wear rain clothes so you stay dry. And if it’s really pouring just wait half an hour or take the bus if you can’t wait. Just plan to ride every day and be okay with the days when life won’t let you.
I think what happens is when people have a routine outdoor activity, they develop a sense of their local weather, that seems like a mystery if one isn't regularly immersed in it. Also, some subtle adaptations make it easier, such as wearing quick drying clothes or having an emergency change at work.
Now, I do have the luxury of flexible hours at my workplace, but (for instance) my daughter doesn't, and she manages just fine.
