are there any places up north that, on a particularly cool year, get autumn leaf change in August or so? I'm of course referring to METEOROLOGICAL summer only, so seeing the leaves change on September 15 does not count. We're talking about weather, not the position of the Earth's tilt. So I mean places that at least on one occasion, have seen autumnal conditions in vegetation before September 1st
Interesting you chose Meteorological Summer vs Astronomical. See below if it counts.

Here too. Late August-Early September if conditions are right I "START" to see signs of changing colors. (no its not stress for those that like to use that excuse). I thought it was, but it wasn't. It's nothing crazy but you can see the changes starting in August.
By Mid September its more noticeable. By Mid-late October we peak.

Seeing so many more changing colors out there now.
Pound Ridge in southern NY near CT border this morning
RT 123 in New Canaan, CT.

This is 250' elevation in SW CT near the coast. Nice cool fall day.
Yeah, that's what Småland looked like in mid-August as well.
And also, in the July/August shift I was in Stockholm, and there were a lot of yellow/brown trees. I was surprised because there were none in Umeå. I guess it had to do with sickness though. Still, it was interesting because there were loads of seemingly dying trees whereas I've never really seen that in Umeå.

Aargh, not this again, and you're correct.
There are many fungi which makes the leaves yellow or dead, it's called tree rust.
Yeah, the Stockholm thing was probably something like that, but in Småland in mid-August lots of trees, maples especially had large red and orange sections on them.

It's also a fungus and the leaves change colours due to stress.
I took these on 24 September 2014, not much fall colours there. And I'm at 60N:
Hilarious seeing people using stress and fungus as an excuse. If that was the case it would be a select few trees, not widespread in entire area and multiple trees which then others follow with the changes of colors.
Its the beginning of changing colors. Fall.
Brown, droopy, thinning, dark spots, falling leaves is an easy sign stress. When trees are changing colors just weeks before the rest usually does, you cant jump to say its stress. Lol. In July you can.
Hmm, I guess so. But why would it only happen in August-September and never in July or earlier in the summer?
If you get HIV do you die instantly? No, you die when your immune system and strength collapses.

These fungi spread, and fast. The ash dieback I mentioned contaminated almost every ash in my city in 3 years. Now the city gardening section is prohibited to plant more than 3 ash threes in one spot in order to prevent the disease to spread.
