does it have to be hot out to get a tan?
its like 75 degrees out..is it hot enough to tan?
Yes. If you stay out long enough, you can even get a sunburn from an overcast day :)
Tanning comes from the ultraviolet (UV) rays of the sun. You can tan on a cold day, or under a cloudy sky (since UV can come through clouds). Heat doesn't really come into it.
