It is possible for the number on the scale to be affected by temperature, texture of the floor beneath it, tilt of the floor beneath it, moisture, the way you stand, etc.
I'm currently trying to learn to use the scale as a guideline and not give it too much credit. To read the number as, "Well, your weight is around X number, give or take a few pounds." It's kinda tough. But there's so much that can affect the scale or daily weight that has nothing to do with fat loss. I'd rather not spin out over water fluctuation or a chilly bathroom floor. Rather than try to account for all that, I'm trying to go on whether I've been on plan or not, and realizing that the scale may vary based on any of the above factors.
But yeah, it's kinda wonky how that happens, isn't it?
It reminds me of my cousin who plays the violin. He complains that when temperatures/moisture levels fluctuate, the strings loosen, the knobs lose tension, the bridge shifts, and a host of other issues that cause sound problems.
