Gawd............. even my Herety still comes out and it's 20 years old............. if the weather is OK, use it. None of my bikes get wrapped away, I have a daily commuter, 'training' road bike, 'best' road bike and an MTB. TBH the Best bike gets more use than the 'training' bike.....now I have a daily commuter..........
Carbon....not only melts in sun, dissolves in water, and is instantly turned to gas in salt ! Just look after it...........
Lots of nice days in winter..................... just cold........oh yeh, carbon goes brittle under 5c, and melts over 20c...........
