I'm with @noglider. If you take an extended period of time off of commuting it'll be so much harder to get back into it. Last year I took the whole month of February because every morning the temp was -20C or colder. It was not very enticing to go out. Even mornings when I could have gone out because it felt calm enough and roads clear enough to ride I opted to not. The longer I went without riding the easier it was to say, just screw it. I'm driving.
