Temp increase at night

[Adz_k187]

Hey all, I have a homemade still air styrofoam incubator I’ve made for the very first time, something has made me quite curious though, why does my bator temp increase during the night? I live in the UK where it’s quite cold at the moment, I thought it would be the opposite and it would get colder during the night, but when I wake up and check the bator the temps at 103/104F rather than the usual 100/102F. I have sort of combated this problem, usually during the day I put on two blankets ontop (I need both otherwise temp is 96F) but when it comes to night I take one off. Just wondering if it’s the same for anyone else. I hope this doesn’t sound like a silly question lol, I’m still learning!

I hope someone can give you helpful suggestions.
I did use my own DIY still air incubator but it was a constant battle with temperature swings 98 to 104F. I had 8 eggs in there, they all got cooked and never hatched. So I made a new DIY incubator with a digital thermostat and fans. No more temperature swings after that.

oh no well I hope my lil guys are alright I’ve read a lot of stories about bators teaching 104 for hours but still coming out okay, or having a somewhat reduced hatch, I’ve only got two Pekin eggs so I’m rlly praying here

Depending on power transmission lines sometimes voltage will go up at night because of lower usage. I've welded in places where I had to turn the amperage down when the second shift in local factories let out. Higher voltage could cause a higher temperature with the same setting.

Woah I’ve never thought of that possibility, thank you that makes a lot of sense.
