The UV index is not the warm sensation of sunlight on bare skin

    I think I got the worst sunburns when I didn't feel hot at all.

    Usually, it involves water, water cools you down, so you don't feel the heat, but it doesn't block UV, so you don't get the warning.

      Overcast days are the worst offenders for sunburn because the melanin impaired don’t feel the heat of the sun to remind them they are going to roast.

        Depends which part of the world you are in. I've never been sunburnt on an overcast day where I live.

          One of my worst sunburns was in San Diego on an extremely gray day. I should have known better.

          The right thickness marine layer can make the sky seem dim but it's like one massive UV diffuser from horizon to horizon.
