Now, along with the Bad Hair Day cities, I am going to start posting the highest UV cities.
For a description of the UV scale see this link http://www.epa.gov/sunwise/uviscale.html.
Basically, a higher UV index means that the sun’s rays are more harmful. If the UV index is 6 or higher you should apply a sunscreen with spf 30 (according to EPA). But you may want to protect your skin everyday if you are going to be outdoors.
Here are today’s highest UV cities.
