See, I can see where a lot of these come from, and I do agree with at least the first three. However, I live in North Texas. Mid December to early February is winter. Late February to March and April is spring. May to early October comes with actual heat stroke inducing temperatures. Early October to mid December is what you could call "fall." It starts to get pretty chilly around early to mid November.
It acts pretty much the same way here temperature-wise (even the times you described were accurate), and that's normal for subtropical climates.
I recently made this diagram to compare the Canadian and Southeastern U.S.A. temperatures to each other, and "normal" temperate Meteorological seasons: Yes, Carbonyx and finch_rocks_1, these are partly for you two, especially since Carbon (like I) lives in a warmer climate and finch in a cooler climate.
