+1. Also, just to call out, it doesn't need to be _warm_ for you to need sunblock. Even when it's cooler / cloudier out there you can still get skin damage. Look for UV rating rather than temperature. Conversely, it being hot doesn't imply high-UV either.

I didn't know about the UV index or what it meant until like three years ago. It blows my mind I went that long without understanding. It was actually wonderful to learn that I could just see if I needed sunblock based on a 0-10 scale.

We never wore sunscreen as kids because we didn't burn. I probably have had three sunburns in my life. Learned once I became an adult that that wasn't sound logic...
