For keepers of indoor succulents in the cool temperate northern hemisphere: 

While most arid-climate indoor plants should not be watered between around October-March (some people say September-February, and I’m never that precise about the exact date to do so), it’s worth keeping an eye on them, especially if they are in an exceptionally bright location. 

Some of the south-facing windowsills in my house receive many hours of sun in winter and can get very hot, and as such I have to water some species, especially very young/small plants and those in smaller containers. I suppose I’m also an exception to the ‘rule’ because I do use a very free-draining compost mix, and thus I find increased irrigation is required.

I should add that this ‘rule’ is there to keep cacti/succulents bought from most shops where they are potted in a very dense, highly organic mix (why do they do that?) alive for as long as possible, by reducing the risk of rot over winter.

Of course, this does vary with species, as different plants have different adaptations and requirements. Therefore research about each is essential to understanding how best to emulate its natural environment. But it can even vary from plant to plant, and can be affected by age or root development.

To conclude, be vigilant to changes in your plant’s growth at all times of the year, research your plant’s needs where possible, and remember that the not-watering-in-winter ‘rule’ is merely a safety net, and all plants and households are unique. 

I watered all the succulents on the windowsill in my office, as the radiator is on in there a lot, and it’s also very bright (south facing with no obstructing trees/buildings outside). I tend to wait until March 1 to give all of the indoor plants I haven’t watered at all over winter their first soak,  but I think light levels are sufficient now for them to come out of dormancy a few weeks early, as I don’t want them to have to put up with the warm drought any longer. 
What you should really do is not have plants above a radiator that’s on a lot, or indeed in a room that gets very warm. But these manage fine, I just have to keep an eye on them. I didn’t have to water any over winter, but they are looking rather wrinkly now, so it’s time to wake them up a bit earlier than the rest of the houseplants. :)
