I guess we all get used to working within the annual range of temps and other seasonal factors that impact our brew sessions. I've always loved winter brewing. Brewing in winter in Spokane, WA outside, in my situation I keep an eye on weather reports and brew on days above freezing so no frozen hoses or creating a skating rink.
Luckily I have a very good LHBS so no worries about frozen yeast in the mail, etc. and an advance call to him ensures he will add any liquid yeast order needed if he doesn't have it in inventory.
The best part here is very little in the way of airborne particulate and no bugs, and the very cold ground water temp that makes chilling 11 gallons a breeze with my immersion chiller. Also it's a source of activity and getting out of the house. I don't mind dressing more warmly to adapt to a little chilly weather. Still, I must admit that the couple winters I lived and brewed outside in more temperate Maryland made winter brewing a milder, more relaxed, obstacle-free and sometimes spontaneous experience in comparison.
