I really like the last photo!
On the western coast form Pori to Kokkola at the least, they celebrate the end of the cabin season in a festivity called Venetsialaiset at the last weekend of August. There are bonfires and fireworks. That last photo reminds me of the final weekends of the summer when the air is still relatively warm but the evenings have become notably darker.
I’m pretty sure they do that all the way up the coast. I was in Raahe :)
That last photo is taken while I tried to sneak to the huussi without waking the baby that slept in the same cabin 😁
