There's some seriously basic science "fail" in full display on this thread.
Y'all need to read up on the effects of the the earth's "tilt" and "orbit". It will help most of you immensely.
Geez, Iknowright? This is like, 4th grade science stuff. Did some of these people not go to elementary school? Or do they simply lack the cognitive ability to understand it? Very disturbing, either a sad indictment of the school systems, or...

No kidding. The same type to go out with sunscreen on a warm February day even though the sun it too weak to do any damage at all. Or the same type to say the sun is really strong because it is hot outside.
I keep hearing talk about how the "strength" of the sun declines as we go into winter, which I don't think is entirely accurate. I do know that as the sun slants, the solar energy is spread out over a wider area, leading to a decline in temperatures, but if you hold up a board (or solar panel) to match the angle of the sun, its rays would be just as strong as you would get in summer - perhaps even more so due to clearer skies and the sun being closer to the Earth in Jan than in July.
Like when I was in the mountains the other day, being out in the sun felt downright warm, while the shade was on the brisk side. I do suppose the UV is lower due to the sun traveling through more atmosphere, but the way it feels on the skin is like how it feels in summer - with the cooler air temps taking the edge off the heat, if that makes sense. Indoors, the sun feels just as hot as it does in summer - so I can't tell any difference there.
What do you folks think?
I still wear sunglasses in the winter. I guess I might have sensitive eyes, but the reflection of the sun from the snow bothers them sometimes.

Winter sun can cause minor sunburn. I've seen it a few times at work, during periods of prolonged high pressure.

The strength of the sun is pretty constant. It's where you are on the planet and your current inclination of the sun.
I mean, you realize that when the strength of the sun is waning for you in the Northern Hemisphere, its waxing for someone at an antipodal point in the Southern Hemisphere, right?

They must have been very pale. It takes me a couple of hours of complete exposure to get burnt in 11+UV
Winter sun here in Melbourne rates around 1 on the UV index...

Yes, I understand all of that - the N Hemisphere tilts away from the sun in winter, etc. But when I stand behind that window on a sunny Dec day, it feels just as warm on my skin as it does in July - so yes, the "strength" of the sun is the same in that regard.
So I guess the explanation for the "weakness" of the sun is particularly acute in the high latitudes when it fails to rise high enough above the horizon for its heat energy to be felt on the skin, or through a window or what-have-you.
One thing's for sure - if it gets up into the 70's here in January, and if it's sunny, it's gonna feel hot out in that sun, regardless of what the UV index is. In South Florida, sunscreen is needed all winter long if you have sensitive skin.
