Isn’t it more that cold weather makes people gather together in enclosed spaces.

It’s a combination of different factors. Cold weather makes it harder for your airways to defend themselves. There are I believe some cold viruses that are viable for longer or are stronger in cold weather, but since the cold is many different viruses I am not sure how much difference it makes.

True. Influenza viruses don’t like heat. You can potentially reduce the amount of active cells substantially by going to the sauna. 60°C is already sufficient to reduce it by 4 orders of magnitude.
