How cold can it be to snow?

Answer 1

It's typically near freezing or not too far below. When you get below 15-20 degrees F, it becomes difficult for the air to hold very much moisture, so if it snows it will not generally snow heavily.

But under certain conditions it can snow at a few degrees above freezing, though it rarely sticks to the surface. It is possible to snow when the temperature is in the 40's, but this requires unusual atmospheric conditions and rarely lasts long.

Answer 2

Contrary to popular belief, it doesn't snow very often in Antarctica. Antarctica is actually home to one of the largest deserts on Earth. That being said, colder climates make it more difficult for it to snow, but does not make it impossible to snow.

It can't get too cold to snow here on Earth, but it can be too dry. Colder climates like the Arctic and Antarctic often get less snow than warmer climates at lower latitudes, but that's because of the relative differences in atmospheric moisture, not temperature.

Where I live there seems to be some sort of treshold at around -12 degrees celsius, as precipitation becomes more and more rare beyond this point, and is almost unheard of when it is below -20 degrees. Of course it could happen, but then it is really a question of efficient transportation of adequately humid air, and not so much about temperature.

Answer 3

Snow is by definition water that is frozen. The temperature does have to be water-freezing for it to snow but it does not have to be Mercury-freezing. The exact temperature at which water freezed does depend on other factors. Presure most notably affects the freezing point of water as does the purity of the water. So by "freezing" you mean cold enough to make water freeze given the current conditions, than snow is a sure fire proof that it is in fact freezing.

Answer 4

There really is no set temperature. When you get way, way below zero, you can still get "snow". It's basically diamond dust though, which condenses (deposits, actually) right out of the air at those vapor pressures. Though that technically isn't snow I think because it isn't precipitation. Either way, there is a very long spectrum of types of snow, and it can snow way below zero Fahrenheit.

Answer 5

It has to be less than five degrees Celsius at the very most to snow. Generally, it happens more at about one or two degrees. It can also be too cold to snow, at -273.15 degrees Celsius, but this rarely happens on Earth.

Answer 6

Well snow isn't cold at all! It has to be at least 50 Degrees Celcius to snow. So when it's that temperature chuck on your swimmers and go play in the snow!

Answer 7

it needs to be 32 degrees fahrenheit or lower to snow

Answer 8

no
