someone told me that it is more effective to tan on an overcast day. I can't help but think that you only need to spend less time in direct sunlight because there is no interference. I do understand that clouds don't directly block uvlight, but they do lessen it. how could having clouds in the sky be better for tanning?

"5. You may have heard this: "you can get a sunburn just as quickly on a cloudy day as compared to a sunny day". In many cases this is completely false. On an overcast day, especially an overcast rainy day, the amount of UV reaching the surface is significantly reduced. Any overcast conditions will reduce UV radiation reaching the surface. With this said, partly cloudy conditions do NOT reduce the sunburn risk much. Some people make the mistake of staying outside longer when there is cloud cover. This increased time can make up for the fact there is less UV radiation reaching the surface. This mistake is worst on a partly cloudy day."

I think you'll just stay out longer because you won't get hot and sweaty.
