We have been in Feb for 7 out of the last 9 years, generally it is like a good summer here, this past Feb was a bit cool, my dad only had his shorts on twice, but he's a wuss. We wore shorts and T's most days but not the strappy vest tops that I normally wear over there. We swam most days. We have always gone to a water park at least one day. The trick is to layer clothes as it can be cool early morning and after dark, that said we watched Illuminations this year without our fleeces on that we had taken just in case. None of our family can cope in the heat so we couldnt go in the hotter months anyway.
