Yes, you can get a tan when it’s cloudy! The sun emits UV rays that are blocked by the clouds.
One way to see if it is sunny enough outside for UV exposure is to look at your shadow. If your shadow appears long and dark, then it is not safe to be out in the sun without protection (hat and sunscreen).
Another way to determine if it is safe to go out in the sun without protection is by looking at your shadow on a white surface. If there are no shadows, then it may be time for some sunscreen!
Summary: You can still get a tan when it’s cloudy! If you want to know if your shadow appears long and dark, or there are no shadows on a white surface then it may be time for some sunscreen. Getting a Tan When It’s Cloudy.
