I don’t think this will be much comfort, but I’ll say it anyway. Here in Finland, you can’t do any astrophotography at all between the beginning of May and the beginning of August, because the sun never goes more than 12 degrees below the horizon. In autumn and spring, there’s a two-month period when you get properly suitable nights for photographing only every third night. From November to January, the sky is often continuously overcast, and in February, when it clears up a bit, nighttime temperatures are nearly –20 °C. Greetings from Finland!
I can confirm this from having lived there many years. Finnish astrophotographers have it tough! Sisu my friend!

Lately, Ive been inundated with "crappy" skies. We had a few good weeks with decent seeing, but lately it's been abysmal . First the high humidity midnight moisture, then there blazing heat (making it an hours long mandatory OTA cool down). Now it seems half the state is on fire, AGAIN! Just when I get my system and gear all dialed in I get this, Im very frustrated. Anyway, I guess Im simply sharing frustration over one of the things we have zero control over; the clarity of seeing and the sky. Check this out:
It’s been unusually cloudy here in Oklahoma this summer as well. It started off very wet with tons of rain and now it’s high humidity and persistent clouds. I’m hoping this will get better as we swing into fall.
Interestingly, I have a remote site just north (50-60 miles) of the fire and only last night did we not image because of smoke. Plus the seeing last week was quite spectacular, at times sub arcsec… But it is only 30 miles inland and not near any cities….

Southern Ontario has miserable weather at the best of times. Usually northish winds give clear skies, but the past couple of years it’s brought wildfire smoke. My area is notorious for rapidly changing weather due to the collision of southward and northward moving air masses. So the clear sky chart looks like a dream a couple days out, only to change the next day to clouds.
Southern Ontario has also been mostly rubbish this summer, on top of an already brutal Bortle 8, we’ve either had streaky clouds, bad seeing or smoke, and of course the smoke always is at its worst during otherwise clear nights!
This summer has been a complete bust here in the Midwest. Either smoke or clouds or both. We just had 10 inches of rain in a few hours leading to massive flooding and people’s basements flooded and belongings damaged. So I guess astrophotography takes a backseat compared to larger problems people are facing due to the the weather.
