Word sleuths: trying to recall a word for cool early fall weather, or the change in weather?

Maybe it is in this list?
Or you may try reversedictionary?

Not sure why the word fluvial comes to mind.

@mazingerz88 Fluvial means ‘of a river’. A fluvial plain means an area of river bed and the section that often floods. I love those words. Fluvial and alluvial. They sound so rich. I wonder if Kate Bush ever sang about them. They sound like words Kate Bush would use.

How about autumnal?

Well, that would be too easy to remember and not be much of a new word for me

But that might be a good word to begin with if I can get my hands on a GOOD thesaurus.

Are you thinking of Indian summer? It’s an unseasonable warm spell after the weather has already gone chilly.

No—and its definitely the cool snap that comes in early fall.

Thanks

@Jeruba I was trying to think of the opposite term of ‘Indian Summer’... but I haven’t found any. but I did find a lovely reference involving some terms I vaguely remember hearing…..

Autumnal Equinox, doesn’t sound like what you’re thinking of but it’s all I got.

serotinal?

If only @gailcalled were around to answer this for us….

hoarfrost?

@omfgTALIjustIMDu hoarfrost means ‘hair frost’ and another name for a frost formation is rime frost. I keep running into the Langston Hughes poem, Early Autumn, but I still can’t find any particular word for an early fall. A ‘fall front’ or a ‘cold front’ in weather terms, maybe?

I think eventually someone will find it so lets keep the question open. I stumbled across it actually over thirty years ago in an old dictionary and wrote it down. But I wrote down the wrong word somehow and the wall map I wrote it on is long gone. ’

Then, Someone introduced an essay using this word and definition about a month ago and I recognized the long-lost word and its definition instantly but I didn’t write it down and don’t even remember the source. I cannot believe I let it slip by me. Its no common word.

Thanks for all your help and intellect involving word knowledge. If I can get my hands on a really good Roget’s Thesaurus (which used to be considerably bigger than the ones today, if you can even find one) there is hope still.

I admit I am a little obsessive/compulsive, I love words and I love the cool relief of the first autumnal nights after a hot summer – cannot stand not having the knowledge of what this word was. I appreciate greatly all your efforts because no one has to answer anything at all. That’s what I love about Fluther.

edit, sorry, what I found had to do with spring cold snaps. There are some cool ones, though like Lindsey-Woolsey Winter, and Blackberry Winter.

I didn’t see what was deleted or moderated— but even ‘wrong’ answers explore new words and concepts. For instance, I discovered my favorite time of year is PREVERNAL—that time between Winter and Spring,

I almost wonder if I heard the word Serotinal for my famous missing word. But two things make me think not: (1) Serotinal is still high-summer and not cool weather, even though it comes AFTER the summer. (2) I probably would have recognized the word Serotinal from the six season “Estival / Hibernal” model which I was already familiar with I called the Serotinal season the “Back to school” season, where, as a kid, there is still a week or two of summer but you know Summer Vacation is almost over and there is definitely a change in the air, the sunlight and shadow, And all the “back to school” sales. All of this has been rendered null and void now that school starts in early August where I live.

What about a Florida Winter?

I’m not sure any of these are the word you’re looking for, but here are some things I found:

“Katafront” and “anafront” as two different kinds of cold front? I guess katafronts are generally drier, and anafronts generally wetter. The explanations I read were beyond my knowledge of weather patterns (which isn’t hard, I don’t know much about weather patterns), so please do look them up on your own to see if you can make more sense of them. They’re not autumn-specific, from what I can tell, but since autumn is a transition from warm weather to cool weather I thought there was a chance they were more common during autumn? Really not sure, though.

Canicule. While this is a heat spell (the dog days), I thought the origin of this term might be helpful—that it comes from the position of Sirius during a particular time of year (or at least where it used to appear). Perhaps the word you’re looking for also comes from an astronomical pattern that people observed and named (or some other natural pattern that recurred as the temperature began to fall)? Not sure if that helps with the search, but I thought there was a change it might, so I thought I’d share it.

I have heard some say that the ancient Egyptians named the star Sirius, or the dog star, for the ‘dog days’ (Canicule) because it was the hottest time of the year when the star first became visible again before the morning light. Or, maybe perhaps when the sun eclipses Sirius earlier in the summer. But even in the dead of winter, when Sirius is most visible, it could be named for its ‘searing’ light.

We always say that autumn brings a little nip to the air. We also describe it as crisp, fresh, light, and clear. Where I live now we have summer 12 months. I really do miss the seasons.

Gettin’ a might nippy? ( Don’t think there is one word but “autumnal” is probably the closest.)

Yowe tremmle?

It’s a cold spell in summer.
Does that count as early autumn?
