can coolant levels decrease a little overtime because of evaporation and hot weather conditions?

What is your question?

my windshield wiper fluid sometimes leaks and makes a puddle on the ground. And whenever i see these puddles, which is rare, i always check my coolant levels too just in case. i noticed it was maybe not even a half an inch lower than normal. and the puddle was too dry for me to test the color of the liquid leaking. so i topped off my coolant but i’m nervous to drive my car now. i didn’t see any visible leaks from the cap on the top or any of the hoses. i even got under my car and couldn’t see a leak from the bottom. so i’m assuming it’s my windshield wiper fluid. but i wanted to check on here if it possible to lose a little of coolant over time because of evaporation?
