Wait.
What is this secret, arcane knowledge and why does it explain so many things? Like how it never seems to rain in my playthroughs, especially in Summer as it's too hot out to take care of more than maybe a Chicken or two. If I don't have Sprinklers yet, I just skip to a time where Farming is discouraged, like Winter or Year 3. Just check under each Tree in the Valley for the skip button, one snoozeundertree per day, it's totally there.
But now I know it is my own private perspirations that seed the clouds of Stardew, that control the old growth of Trees and Flowers around the Valley that I must Chop and Forage. The sweat of my hard work and personal peripatations are the drivers of Pelican Town's climate and ultimately whether I'll finish the stinkin' Fish Tank Bundle with that blasted Eel and Walleye. After which I'm reminded of my hard-earned reward:
A Copper Hat
Wow.
Ok, shouldn't complain as it's technically Clothing that I can wear at Spirits Eve to look like part of the Very Large Array in New Mexico.
