You can leave any heavy wool coats behind.

It gets cool here in "the winter" and layering is really your best option. You will probably buy a pashmina scarf/wrap and this can help keep you warm in the "winter."

It is hotter than hell here now and it will get even more uncomfortable in August!!!! Despite the heat outside, most buildings keep their A/Cs running full blast and it gets a little chilly in the malls/restaurants.

Bring your light sweaters. You can use them year 'round.
