If fresh water were -9 degrees F, I suspect it would be solid ice (it could be super-cooled if it were absolutely still, but lakes and rivers are not that, and splashing in super-cooled water would turn you into a popsicle). The air temperature isn't even that cold in any of these pictures.
- rmason 7y agoActually if you read the link you'd see one of the polar bear events the temperature was -8 degrees fahrenheit. I've watched similar events on TV where they actually cut a hole in the ice to begin the event.
- paulcole 7y agoDo you mean the first photo where it says 8 degrees above zero?
- finnh 7y agoThat's air temp, not water temp. We are discussing water temp.
- anamexis 7y agoThose are air temperatures, not water. Being fresh water, the liquid water is not below 32F/0C.
- dancek 7y agoNit: flowing water does go below 0°C without freezing, as does water with impurities (sea water).
