About this snow cam
Mauna Kea, Hawaii, United States, is at 19.82°N, a low-latitude latitude where snow is very rare except high in the mountains. This page shows a live camera with the current weather at its exact location, so you can see the conditions for yourself.
In a typical year, Mauna Kea gets most of its snow January, if at all. That is a rough guide based on latitude alone, and nearby mountains, lakes or the sea can change it. The camera and the 24-hour snowfall on this page show what is happening today.
This camera looks out over Mauna Kea: streets, rooftops or the land around it, depending on where it points. The picture is live, not a recording.

Usually January, if at all, going by latitude. Snow is rare here, so any snow on the camera is unusual.
The snowing or not snowing label comes from the weather model at the camera's exact coordinates and is refreshed about every hour. The model can be wrong, which is why the live video is on the same page.
Yes. The live map shows every camera, and the Snowing now only filter shows just the ones where it is snowing.
Snow is rare this close to the equator, so on most days the camera will not show any.
