I used to hate rain but now I like it. If you are well prepared then riding in rain can be a thrill!
One of my fave experiences from last summer's tour was when the day went from blazing hot to torrential downpour and then hailstorm in what I think was about 30 minutes and then cleared back up. The roads flooded and I was almost up to my axles in water in places. I couldn't resist yelling out "whooOOO!!!!!!!!!" As I cruised through it

With good rain gear you'll eventually come to enjoy rainy days. You don't have to wear sunscreen in the rain and that's a plus.
I find a baseball cap, rain gloves and shoe covers make it a pretty benign annoyance at most. You have to have cycling glasses too of course; mine have interchangeable lenses so I can switch to clear when the rain falls.
Oh and a tarp makes camp enjoyable.
