Another interesting one is Mercury. There is a latitude where the average ground temperature is comfortable for us. You simply need to dig in deep enough to put enough thermal mass above you to get that average rather than the swings. I don't know how deep that is on Mercury, on Earth 10 meters is enough. Real world, you'll want to go a bit farther towards the pole so your station is comfortable with the thermal load of whatever equipment you put in it.

the swings?

Assuming they mean the ground acts as a heat sink, and sufficiently underground you’re not subjected to the above average heat of the day and below average cold of the night.

Isn't mercury tidally locked? Day is always day, night is always night.

It is not (it has a 88d year, and a 58.65d.. day[0]) , we just had a post about it - if you travel at 4kph you can chase the sun.. A Mercury Rover Could Explore the Planet by Sticking to the Terminator (18 points, 1 week ago, 6 comments) https://news.ycombinator.com/item?id=47720941
