I keep coming across people referring to "late summer" and being on the verge of a seasonal change. Admittedly, I don't spend much time outside, this time of year, but I'm not seeing it-- or more to the point, feeling it. Notable: None of them live around here...
So, I'm still counting the days until the end of September. October is the Best Month of the Year (weather-wise, at least). ;o)
