We were on the Liberty (balcony #7351) back in late January and early February. We had to keep turning the air down because it just felt too cold. Never looked to see the actual temp, but it was definitely cooler than the dining room in which I normally freeze. Outside it was pretty much in the 80's all day.
I know that doesn't answer the question if it is a summer time thing - but hopefully adds to the research a bit.
