Of course warmer weather is better for cycling. It's quite a nuisance having to pile on the layers. Maybe I wear more than I really need to; but I live where it's humid, and humidity exaggerates temperatures. Spokane in the 'teens is more comfortable than New Orleans at 40 degrees, simply because it's less humid!
I'm glad the weather outlook for this coming Sunday is OK. I really need a long ride again. Tour de Cure training rides will probably begin before long, and I want to be ready!
