I don't. But no fall at all in my part of FL. Just goes from insane hot to hot year round. Maybe 4 days are colder and nothing like the 1980's when we had real winters.

High temperature of around 75F, low of 52F tonight. I'm guessing for the city it will be 82F and 61F lol.

I actually think the term 'meteorological season' makes no sense when it's applied to that. There's nothing more 'meteorological' about saying fall starts on Sep 1st than saying it starts on Sep 22nd.



The reason for the scientific use of those 3 month blocs is primarily one of methodological convenience. It's simply more suitable for statistical calculation.

It also happens to coincide with the warmest and coolest 90 day periods (for summer and winter) in most of the world

Also, if you use the astronomical seasons, Spring happens to be much warmer than fall in most of the world, compared to the meteorological seasons

Will certainly feel like fall for a good chunk of the eastern 2/3rds next week as summer rolls on out west according to the Euro




Now check what the 12z run of the GFS is showing

It will differ strongly from location to location. In the D.C. area for instance the first 10 days of September are on average warmer than the first week of June. This is not uncommon for climates near coastlines at all due to the seasonal lag caused by the sea. It's similar for instance in coastal UK/Ireland or the U.S. West Coast. In fact in quite a few locations on the West Coast summer only peaks in September and September is notably warmer than June.



I recall reading a definition of meteorological seasons in a textbook describing them as being highly variable based on location while the simple 3 month bloc division was instead called "calendar seasons".



I can see why 'calendar season' isn't popular though as it could confuse people. A lot of folks would think this means the seasonal start and end dates as marked in calendars (which typically refer to the astronomical seasons).

Conversely, in the Arctic, winter is already starting (de facto), even though today is just September 1st

Sept 23rd is fall and that is all there is 2 it. But we never see any 50's anymore it seems until Nov. Nothing like the real falls we had in the 1980's when Sept 17 and 18th saw a 58f and a 62f at my house in Tampa in 1980 if i remember right. That was just a freaky thing as i won't ever seem them temps again in Sept.
