What reminds you of summertime?

It's like in the middle of the school year and I am just in one of those ruts and I'm trying to mentally get in the summer mood... so what are the things that remind you of summer? Some of the things for me are sprinklers, concerts, staying out late, waking up to birds singing, the smell of suntan lotion, how you skin feels all tight when you've been in the sun for hours at a time, having to wear sunglasses and searching for a breeze because of how hot it is.. please help me add to the list!
