During the day it can get quite warm. The past few times I've gone with my family we have brought a whole assortment of clothes. Shorts, pants, hoodies, scarves, wool hats, gloves, heavy jackets. During the day I wear shorts and short sleeve shirts while my dad wears pants(only wears shorts during our august trips) and short sleeves. My mom and sister(13) wear caprees and short sleeve shirts. Then once the sun starts to go down it gets very cold. It gets to around low 40's, but its a different low 40's for us in the northeast. It gets cold at night so i change to pants, put on my hoodie, jacket, wool hat and gloves. and then I am nice and warm. This is also the worst time to go with suitcases because of the weight limit on the airlines. Grrrrr.... curse those airlines! heh
