Hi
I'd say bring a bit of everything pants , capri's , tshirts , and sweatshirt and maybe a coat ( lightweight ) when we where there feb 07 -08 -09 we had just about everyweather specially feb 09 it was quite chilly ...so I wore mostly in the mornings capri's , sweatshirt ( tshirt under it ) around noon some days I'd take off my sweatshirt and be in my tshirt had to put my sweatshirt around dinner sometime I needed my light coat on top .
But I'd say I love my mid winter trips and I like that weather better than sweaty , humid , hot july / august .
You'll have a great time !!
