And a parka!
Thank you all for the replies. Been a lot of years since I had p-chem and physics, so the heat-vs-temperature concepts had faded somewhat, but I see what you’re saying. No atmosphere, no convection, no balmy summer day-like locations; forecast calls for temperature and radiation extremes highly dependent on local conditions.
Fascinating how different the rest of the universe is from the way we experience things on Earth.
