(I'm not OP) Why not? I ride even during storms, much less shying away from what, some cold winds in winter? By the time you reach your destination if you're wearing the right clothing you not only won't feel cold, you might even feel too hot. If I ride for longer than 10 minutes I need to open my jacket or put it in my backpack to let some air in to prevent my body from sweating.
Of all the seasons I'd name summer as being worse to ride than winter because there is no getting away from the fact that you'll be drenched in sweat during summer. Thankfully I don't need to go to work on a bicycle because we have great public transportation here in France, so I mostly use it for other things and just for the sake of it (I like cycling). Cycling to work would not be convenient during warm seasons, to say the least. Winter is the best, just get a jacket that protects you from the wind, some gloves and decent shoes.
But you also have to go to grocery store, go out with friends, do errands which most of the time are scattered across the city, it can take multiple rides per day as well. Also if you have kids you should add dropping them to school and other stuff. So you end up spending lots of time waiting for uber and paying for this little trips.
