San Myshuno weather always warm and partly cloudy

You could try moving your Mods folder to your desktop and repairing your game. In Origin go to My Game Library and right click on The Sims 4. You should see an option to repair the game. Then place your Mods folder back in your Sims 4 folder and delete the cache and localthumbcache.package files (this just eliminates temporary files for animations that may have become bloated, the game will generate new versions) Restart the game and see if the problem persists.

Ah, thank you for the quick response. I wish I could say I did the same haha. Well after playing for a couple sim days I found out that it was just a crazy coincidence that every day that week was warm and partly cloudy because after a few days, the weather was actually something different! I am honestly so relieved because I was stumped on what it could have been. Thank you for trying to help. I appreciate it!
