It depends on too many things to sum up.
Is the shop insulated?
How about the dew point in your location?
-
For instance, if your table saw becomes cold in a non insulated garage at night, and then the air temp rises faster than the temp of the table saw; dew will form on the cast iron surface, causing it to rust.
Same with the table on your drill press, joiner, bandsaw......
An insulated garage can usually avoid this issue.
