For our December, January, and March trips, we packed a couple of pairs of jeans, a couple of pairs of shorts / capris, t-shirts, a couple of long-sleeved t-shirts, one hoodie, and one zip-hoodie jacket for each of us. If the weather called for cooler days, we layered the long-sleeved t-shirts under our short-sleeved ones then took them off in the parks if the weather warmed up. We needed the jackets a couple of times but only once was that for all day. We ended up wearing both jeans and shorts as we had some warm days and some cool days.
