Needs to be just below freezing.
Water which is in motion freezes at a lower temperature than when it is still.
A drop of water runs down a roof and stops to form a drip at the edge. The droplet freezes to the edge as the freezing point of the water rose when it stopped. The water also has less exposure to heat from the roof when it is hanging from the edge.
This occurs again and again and builds into an icicle.

Icicles start to form when the temp. gets below the freezing level. The water drips off the object and when it starts to freeze it starts the icicle effect. The top layer of the ice is formed allowing the slow run of water on the outside, the more the drip, the longer the icicle becomes.

Just has to be below freezing (32 degrees F). They happen when water is dripping off a ledge, but it's so cold that they stick to the ledge and freeze instead of falling to the ground. More water drips, and the icicle gets bigger and bigger as water freezes while it's running down the icicle. Pretty common in colder weather. I've even got the beginning of a few icicles here in Texas.

Icicles form like stalagatites.
Cold water drips until it forms ice, in the shape of an Icicle.
Usually, they form around 32 degrees, freezing temperature.

The air temperature has to be below freezing while the ground temperature is above freezing. Typically, they form when snow or ice melts on a surface that's above ground. The water runs down the side of whatever it is and drips off. If the air is below freezing, some of the water freezes as it runs down. Naturally, the bottom part freezes lower and lower until you have an icicle.

they form when water drips from a ceil9ing and do to the cold freezes while its falling not instantly but like in and hour and a half it should be about 32 degrees and under farenheit ur right it is kinda interesting
