| How much daylight is it recieving?
If using a nearby window he may be syncronised to winter regime.
Do you maintain the same heat at night also?
Its possible that your snake is finding it an extremely hot winter and so he then hides to remain cooler but comes out at night when ambient temps are lower.
What size is the enclosure?
He may feel threatened if it is a large enclosure,especially during daylight hours as he has noticed all the activity within its surroundings.
What side is the hide located? warm or cool?
There could be 100 possibilities but it is hard to help without knowing how he is kept etc.I'd continue trying to feed every week.
