Here in Mojacar (Southern Spain) I have frequently had to point out to sunbathers in early June that although the temperature is cooler than in August, the risk of sunburn is far higher. They seem unable to comprehend that the sun is far higher in the sky, and therefore far more fierce, than in "hot" August.

@Petter I loved spain but here in adelaide we are under a bloody great hole in the ozone layer and it makes a huge difference. You can burn after just a few minutes in the sun.

@Cyklone Sounds like Kenya, in the highlands. Not only is it right on the equator, but at 10,000 feet altitude and with dust free air the UV rays are hardly blocked.

@Petter yep, that would be similar
