Why it is important to wear sunscreen even on gloomy, cloudy, foggy days at surf camp. We encourage parents to slather it on before dropping their kids off at camp and we will reapply during. Here is why.....
"Let me drop some science on ya. Clouds filter out sunlight but not UV rays, the bad ones that cause aging and cancer. The Skin Cancer Foundation says that clouds block as little as 20% of UV rays — so on a cloudy day you’re still getting up to 80% of the sun’s harsh effects.
Some say you’re actually at more risk on cloudy days, since UV rays can bounce off of clouds. According to American Scientist, “Reflection off the sides of cumulus clouds is one mechanism by which UV radiation can become focused.”The science may be hard to grasp, because it depends on the thickness of the clouds and how much of the sky they cover — factors that can change within minutes. But the bottom line is, yes, you should still wear sunscreen on cloudy days." by yoursummerskin.com
