No no not really- tho snow has been falling some places here fall is ussally seen as starting in a few weeks from now offically ( tho it is variable across the country as is the fishing) ( but here it is fromyour fav info source )

Astronomically, some Western countries consider autumn to begin with the September equinox (around September 23) in the northern hemisphere, and the March equinox (March 21) in the southern hemisphere, ending with the December solstice (around December 21) in the northern hemisphere and the June solstice (June 21) in the southern hemisphere.[1] Such conventions are by no means universal, however. An example is found in the Irish Calendar which still follows the Celtic cycle, where autumn is counted as the whole months of August, September and October. In Chinese astronomy, the autumnal equinox marks the middle of autumn, which is deemed to have begun around the time of Liqiu (around August 7).
On the other hand, meteorologists count the entire months of March, April and May in the southern hemisphere, and September, October and November in the northern hemisphere as autumn.[1] Although the days begin to shorten after the summer solstice, it is usually in September (northern hemisphere) or March (southern hemisphere) when twilight becomes noticeably shorter and the change more abrupt in comparison with the more lingering ones of summer.
All of these definitions, as with those of the seasons generally, are somewhat flawed because they assume that the seasons are all of the same length, and begin and end at the same time throughout the temperate zone of each hemisphere.
