I have been wearing flip flops, short sleeve T's, and shorts all winter. Daytime temps average about 55-60F in Jan. It only gets warmer from here

. Mediterranean climate at its best!
I know how lucky I am, by the way. I take advantage of the weather by gardening and growing organic veggies! One of the reasons It's so expensive to live here in my city is because of the almost perfect-weather, even in most of winter and fall.
