Again September is mostly a Summer month in the Northern Hemisphere. As June is mostly a spring month.

And surprise, it really feels that way. Might take a week, (Never seems like it at the start of Fall)

Astronomical Seasons
The astronomical definition uses the dates of equinoxes and solstices to mark the beginning and end of the seasons:

Spring begins on the spring equinox;
Summer begins on the summer solstice;
Fall (autumn) begins on the fall equinox; and
Winter begins on the winter solstice.
The beginning of each season marks the end of the last.

Because the timings of the equinoxes and solstices change each year, the length of astronomical seasons within a year and between years also vary.



I still don't know why on a METEOROLOGICAL forum, people are using the astronomical definition. This isn't an astronomy forum.



In most places, the weather for a season starts way before the solstice and equinox anyway. Do you think that on a normal year, we don't see snow til late December? That's ridiculous. Also, what good is studying weather if you don't use fixed dates? The solstice changes, but September 1st is always September 1st. We get fall weather way before September 23rd. Sure, it can still be hot in September, but I'm talking about average.

Where I live, Tennessee, June is NOT a spring month. And this is a place where spring is warm, average highs have to get above 82 F / 28 C or so for it to be considered summer here. And, winter starts at a high of about 56 F / 13 C or below, again that's the average.

We're usually in our spring pattern by early March, sometimes even February. March 1 is a good approximation, yes it can get cold and even snow here in March but it's a lot less common than January, in the first half of March a majority of days are close to 60 F / 16 C at least and most nights are above freezing, compared to the core of winter itself when a majority of days have a high near 50 F / 10 C or cooler and most nights are below freezing.

Summer conditions usually start before May is out, some cooler years have had spring-like conditions into EARLY June but they never get close to the 20th. Most years, the beginning of June is full-on summer with high temperatures near 85 F / 29 C on average, sometimes getting into the 90s / 32+ C. By June 20 (the summer solstice) we're averaging highs close to 90 F / 32 C and it's almost indistinguishable from the height of summer in July and August.

I'll give you the fall equinox, our summer conditions seem to go later than September 1 usually, a lot of times right up to the fall equinox and occasionally into early October (gasp). But fall is over WELL before December 21, December is quite a cold month here and even late November is quite wintry.

The way I look at the ridiculousness of the equinox system (at least for where I live) is to compare the conditions at the start and end of the astronomical seasons. The idea is that winter and summer SHOULD have similar conditions at their ends (e.g. the first day of winter and last day of winter should have similar averages, ditto for summer). But December 21 is MUCH colder than March 21, and September 23 is cooler than June 21 (although not as drastic of a difference).

Agreed. June has more 90F+ days than September and is more likely to get 95F+ days. Also, it's often felt like winter for almost a month by December 21 and spring for over a month by March 20.

We did get a lot more 90F+ days in September this year, but we had a high-pressure system causing a heatwave and drought, while we had a random mild spell in mid-June that made it feel more like San Francisco and sent lows below 50F.

Europe also had a hot September. Italy certainly did anyway, based on my travel experience!

Yep, this part really does depend. In southeast Michigan your description is accurate, but where I grew up in the PNW this was actually the stage where grass started to turn GREEN again, from being brown all summer.
