Rain is not necessarily cold by the time it lands, it has a certain ability to sap and dissipate heat as it evaporates. The ceramic tiles in your house aren’t really “colder” than you, but they feel cold because they are very good and transfering heat away from you.
If youre into pedantic debates about properties of molecules, I suggest looking into why water is not wet, and the fan base
The ceramic tiles in your house aren’t really “colder” than you
Yes they are; they’re not warm blooded mammals, and they’re at the lowest level in the house, where the coldest air is.
Ceramics generally have poor thermal conductivity. Metal is a good conductor of heat.
They have poor thermal conductivity, but still much better than fabrics or wood. They also have a high thermal mass.
Tiles are a bit cooler not because they are lower in the room, but because they easily lose heat to the air. They aren’t that much cooler though, and a piece of wood the same temp would feel much warmer.
You can hold a ceramic tile in your hand and apply a blowtorch to the other side. They’re better insulators than conductors. That’s why you see ceramics used for insulating hot food bowls from wooden tables, or a more extreme example, ceramic tiles on re-entry vehicles. Ceramic is not a good conductor of heat.
Wood is about 0.1 W/mK, ceramics about 1 W/mK, and copper is about 400 W/mK.
A more apt comparison would be ceramic floor vs wood flooring, or ceramic vs air temp, not ceramic vs skin temp. Your skin is absolutely warmer than a ceramic floor tile.
Tiles do not feel cooler because they “easily lose heat to the air”. They are the same temperature as the other flooring in your house. They feel cooler because of thermal mass, which you’ve identified. Your body can warm the low mass of fabric or wood faster than it can ceramic, thus those materials feel less cold when you step on them.
If you’re going to be pedantic, at least do it right.
I cannot discern the difference between my arguments and yours. You just used more words? We’re saying the same thing, except I was making a joke about pedantry.

Mfer the OP said the rain was cold. Maybe it was fn cold lol
It aint that deep bruh

rain is ambient temperature-ish and water isn’t wet! fight me! (jk)
