That said, latitude alone doesn't determine climate or temperature. England has a very mild climate compared to a place like Wisconsin despite Wisconsin being 10 degrees south of the UK. It's a pretty general indicator, but there are places on the equator that actually get snow because of elevation. Also the atmosphere retains a fair amount of the heat and cold in the air, which is why nights aren't always the same temperature year round and why summers don't melt the ice caps every year.

Heh, you guys... If we're talking about how dark a place feels to humans, I think sun-hours is a good measure.
But if you want to get sciency, fine. Our eyes perceive light on a logarithmic scale. That said, to calculate how "dark" a place is, you'd have to calculate the sun's normal intensity, take the logarithm and integrate over a year. While the average daily sun-hours actually vary from 3.1 at the poles to 7.7 at the equator (taking the sun's angle of incidence into account), the perceived "brightness" only changes by a factor of 1.08. Helsinki, at 60°10'N is only 1.4% "darker" than the equator, not something a human could easily notice.
