When are the sun's rays the strongest?

Dr. Mehmet Oz, MD

If you expose your skin between the hours of 10 a.m. to 4 p.m., when the sun's UV rays are at their strongest, you are more likely to burn. Use a sunscreen and wear protective clothing to safeguard your skin from the sun's harmful rays.
Dr. Doris Day, MD
Stay out of the sun between 10 a.m. and 3 p.m.

The sun’s most dangerous burning rays are Ultra Violet B. These are called UVB for short. Think “B for burning.” UVB rays are strongest between the hours of 10 a.m. and 3 p.m. Make every effort to minimize your time outdoors during these hours. And remember, the closer you live to the equator, the stronger the sun's rays for more hours in the day, since there is more daylight time in these areas. The sun is also stronger at higher altitudes. In addition, snow, sand, and water reflect the sun's rays and greatly increase their intensity. If you ski or if you go to the beach, do everything you reasonably can to shield and protect yourself from the sun’s rays.
