The Fallout 4 Seasons project provides seasonal landscape overhauls for Fall/Autumn, Winter, Spring, & Summer.
Automatic Season Changes are a technical impossibility at this time.
We've asked several prominent F4 scripting experts. Not even F4SE can do it currently. Yes we know about Powerofthree's auto-changing seasons in Skyrim. Fallout 4 has a precombine system that makes things a bit more difficult. Please don't ask for auto changing seasons.
